Filed in Speaker Building Comments Off on Subwoofer enclosure Dayton II ST255-8 10”

This is a relatively small enclosure that is relatively small and easy to build.  This enclosure uses a 10″ down facing sub so it can work well as a hidden sub.

Parts List:
1 Dayton II ST255-8 10” Woofer – Parts Express $76.78
1 Dayton SA100 100W Sub Amplifier – Parts Express $109.88
1 Acousta-Stuf Polyfill 1 lb. Bag – Parts Express $9.25
2 ft of 1 ½” Inside diameter PVC pipe – Home Depot, Lowes, etc..$2-$3
3 Sheets 2’x4’ MDF – Home Depot, Lowes, etc.. $25
1 ¼ “ or 1 ½” drywall screws
Wood Glue
Paint/veneer/vinyl optional
Total Cost: about $250
Plans: all measurements in inches


Estimated Response



-Predrill all holes for assembly, use wood glue and drywall screws
-Use router and Jasper Jig to for speaker cutouts for fast and easy cutting. Jigsaw will also work.
– For cabinet legs, you can use 2” PVC but can be tricky to attach to the enclosure. If you go PVC route, you will have to cut MDF endcaps with a either a hole saw or a router, epoxy those to the PVC then screw them onto the enclosure. The easiest way is to glue stack your choice of either 3 2.5”x2.5” square or 2.5” diameter (cut with hole saw or Jasper Jig) pieces of MDF. Square is easiest but round probably looks nicest.
Good Luck and Enjoy!

Whole Peanut Wreath Feeder Tips, Review and Squirrels

Filed in Birdfeeding Comments Off on Whole Peanut Wreath Feeder Tips, Review and Squirrels

wreath_peanut Always looking to add new treats for our bird friends, I thought introducing whole Peanuts would be a great idea and surely a treat they would love.  After a bit of Amazon browsing, I though the  whole peanut wreath feeder looked like a great one to try. I then set out to find some whole peanuts which are quite expensive by the way, expensive for bird food that is, approximately $3 a pound. The link above was one of the cheaper options for a 5 lb bag. At any rate, received the feeder and peanuts after a couple days wait and set it out next to our other feeders which consist of black oil feeders.

For the first couple days, not a single taker on the peanuts. They sat their all alone with no love.  In fact, the sunflower feeder was not being rate at its usual rate so clearly the birds were not sure what to make of the new introduction. Birds are creatures of habit so it was not surprising at all. After day 3 and no takers, I took a few out and placed them on the old feeder. Sure enough,  after a few minutes the always save Tufted Titmouse  approached the new treat and made off with it. Next, the clever Downy Wood pecker tried his hand it. By day 4 , the Downys and Titmice were regular visitors to the wreath. I guess after figuring out it was food, they had no problems.

All was well for the first week. Birds regularly feeding on the wreath. As the days went on, the feeder started being drained faster and faster. Finally, on the weekend I was able to observer the peanut bandit, a squirrel of course! Not a bit deal at first, I would add another handful to the wreath and the next day it was the same thing. Then the damn things suddenly got super greedy and the squirrels started draining its entire contents daily. Suffice it to say, I am not going to spend $20 a week for peanuts so peanut wreath feeding ceased once the 5lb bag was gone, essentially in about a weeks time. I will need to try a pole and baffle setup next time as the wreath is hanging from a tree. So now for some lesson learned.

Whole Peanut Feeding Observations

1. Have patience as the birds do not automatically know what a peanut is. Introduce it on feeders that they have been using.  No need to remove the shells, they will figure it out.

2. The Wreath seems to be a popular feeder but it has some drawbacks. If only birds are eating from it, then be prepared to remove empty peanut shells on a daily basis. The birds will peck a hole on the peanuts and take the peanuts whilst leaving the shell. Rarely do they take the whole thing.

3. If you have squirrels, don’t event even bother with the wreath unless you have some sort of squirrel deterrent such as a pole and baffle set up. They will drain all peanuts on a daily basis once the catch wind of it. They will easily eat 5lbs of peanuts a week not leaving the birds much.

4. If you do not have the afore mentioned squirrel deterrent, try other peanut feeders which have a finer wire mesh that does not allow for the whole peanut to be taken it out. Doing so will allow the birds to peck out the peanuts and slow down squirrels. You will of course have to take out the sells every time you add new peanuts.

5. Needless to say, peanuts will make a mess so be ready for that.

Birds Choice Upside Down Grackle Resistant Suet Feeder Review

Filed in Birdfeeding Comments Off on Birds Choice Upside Down Grackle Resistant Suet Feeder Review

upsidedown-suet-feederBefore I review the Upside down Suet Feeder,  let me give you a little background. I have been feeding woodpeckers now for just over a year now. The first feeder I purchased was a tail prop style feeder. I will admit to not knowing the first thing about woodpecker feeding and I was like “If you build it they will come”. After about a week, sure enough they did. All was well until the dreaded Grackles showed up. Now, I don’t have anything against them, they are a lovely bird, that is unless you are trying to feed woodpeckers and other varieties of birds. You see, if you are just getting into bird feeding, whether it be suet for woodpeckers or birdseed for song birds, you will fast discover that Grackles will put you in the poor house. These birds will consume VAST amounts of food. Once they got a hold of the suet feeder, they were devouring no less than 1 entire suet cake DAILY. Not only that, but woodpecker sightings were few and far between.

In frustration, I took the thing down and said forget it even though I still had a full box of suet left. Fast forward to the winter when I noticed the Grackles were all but gone, so I decided to put the feeder back up and lo and behold, the Woodpeckers came back and were regular visitors all winter with 0 Grackles. Fast forward again to the spring and the darn Grackles are back and at it again consuming all the suet. This time, I decided to try something new…


Enter the Birds Choice Upside Down Double Suet Feeder which retails for around $28 on Amazon and is Prime eligible. After some research, I found that Grackles were said to not be as much of a problem if using the upside down feeder. With that I decided to give it a shot, so i opted for the afore mentioned Birds Choice model because it was fairly affordable, it was made of recycled material, it looked fairly nice and most importantly, would deter Grackles.


Before I go any further, let start by saying THERE IS NO SUCH THING AS GRACKLE PROOF! That goes for this and all upside down feeders for that matter. That said, this style of feeder will stop them from eating continuously. It appears they can only hang on upside down for a short period of time, though truth be told, it is much longer than I would have thought possible. Lazy Grackles can only try to feed hummingbird style by pecking while they hover. Luckily they can only do so for 1 peck at most. Another plus is that this one keeps multiple Grackles from eating at the same time.

Construction and Build Quality

The construction and build quality are excellent. The feeder is made out of recycled plastic and claims to be made of 28 recycled containers which I can believe because it is quite heavy and dense. The unit accommodates up to 3 or 4 cakes at a time but unless you have a swarm of woodpeckers in your back yard, i would only do 1 at a time.  and it will accommodate up to 2 cakes at a time.  Screws are all stainless steel as is the cable that holds it up. Overall, it is a well built unit that will last a long time.


Locating Your New Feeder

If you are a seasoned Woodpecker feeder and are replacing your tail prop style feeder with one of these in the same location, then the Red Bellies, Downies, Chickadees and the like will figure it out immediately. If you are installing one for the first time, I would highly recommend NOT installing it in a tree where it will have near by branches below it as Grackles will have absolutely no problem getting to it. Grackles seem to have a harder time getting to it the higher off the ground and away from branches it is.  Mine is installed off the overhang of a pergola and the only way the Grackles can get to it is from the ground.



While this will not stop Grackles, it will slow them down. Your suet cake will probably last 3-5 days vs 1 day in a regular vertical feeder. It’s also worth mentioning  that I have observed more Woodpeckers with this style feeder. Woodpeckers are careful diners so they seem to like the protection from above. Overall, I highly recommend one of these when Grackles are a problem in the spring and early summer. At $1 and change per suet cake, this one will pay for itself in a couple of months.

Jet JFR-12 1/2″ Air Regulator with Built in Filter Review

Filed in Tools Comments Off on Jet JFR-12 1/2″ Air Regulator with Built in Filter Review

If you’ve just purchased a 60 gallon+ air compressor you’ve no doubt discovered that you will now need an air regulator. Unlike the smaller 20 gallon units, the larger ones do not typically come with an air regulator. This is where the Jet JFR-12 air pressure regulator with filter comes into play. This unit has 1/2″ inlet and outlet ports for use with 1/2″ air hoses. The regulator can be had for around $50 for Amazon though you will need some additional parts for wall mounting (see below). Similarly units are priced higher and aren’t quite the same quality as this unit.

Customer Reviews

Build Quality

The Jet JFR-12 Air Regulator is an excellent choice because it’s got all of the features some of the comparable units such as the Ingersoll Rand units do not have. For starters, the Jet JFR-12 comes with a wall mount bracket which is a nice feature to have. By the way, the bracket is the right size such that it fits on just a single wall stud.  The Ingersoll Rand units do not come with one so this alone makes the JFR-12 a better choice. Another reason to pick the Jet JFR-12 is because it has an all metal body construction for long life. The air filter is made of polycarbonate with a metal protective cover. Additionally, the filter has an easy to use moisture release valve that you simply pull to let the moisture out. The top mount pressure control valve is easy to adjust and is made of a durable plastic material.  Assembly is quite easy as all you need to do is attach the air gauge. Doing so is quite easy but you will not be able to use a wrench to tighten it since there is not enough clearance between it and the unit body. Be sure to use some teflon tape on the fitting since you will have to simply hand tighten the gauge to the unit body. Overall, this unit has an excellent build quality and will last you for many years.

Required Parts for Wall Mount Installation

If you plan on wall mounting, you will need a couple of items. Namely, you will need two hoses. I went with a 6′ Goodyear unit for the compressor side, other lengths are available if you need them.  You will need a second short hose if you plan on using a hose reel such as the Goodyear 46741 Retractable Reel. This second hose will go from the Air Regulator outlet into the hose reel inlet.  You will not need this second hose if you are attaching a 1/2″ hose directly to the regulator. You also need some lag bolts or screws to attach the wall bracket to the wall because it does not come with any. Finally, you will need some teflon tape of course to avoid any air leaks.


The Jet JFR-12 is an excellent air regulator for you large compressor. The unit is well built with all metal body and comes with a handy wall mount bracket. Assembly is minimal and performance is excellent. For the price, this is possibly the best air regulator with built in filter out there.

2 Channel Audio Source AMP100 Review

Filed in Home Theater | Speaker Building Comments Off on 2 Channel Audio Source AMP100 Review

dayton es65wThe Audio Source AMP100 is an awesome little amplifier if you looking for low cost amps to go along with your preamp processor such as the Outlaw 970. The Audio Soure AMP100 features 2 channels rated at 50 watts RMS on an 8ohm load , 60 watts RMS on a 4ohm load and a nice 160 watts RMS bridged into 1 channel mono all with great sound quality. This is more than enough power for your surrounds and will work great for a center channel. This amp can also be used as a sub amp if you are powering a small to medium sub.

Audio Source Amp100 Vs Dayton APA150

Though it pushes out 15watts less per channel, the Audio Source is comparable to the Dayton APA150. The form factor is ideal for rack mounting where the Dayton APA150 is more compact and can be placed side to side on the same shelf or rack. Perhaps one of my favorite aspects of the AMP100 is that it is 4ohm stable so you can power just about any DIY speaker you can build. This is a great feature because most home theater receivers are only rated at 8 ohms.

Overall, either the Amp100 or Dayton APA150 would make a fine amp. The power difference is really negligible this just boils down to whether you need to rack mount the amp or simply shelf mount such as home theater applications. I myself have 3 APA150s side by side on shelf for my home theater and they fit perfectly fine. I would have a hard time finding space for 3 Amp100s in my application.

Find More info on the Amp100


The Audio Source Amp100 is an excellent amplifier for the DIY speaker builder in that it can run just about any DIY speaker system you can come up with. It’s also an excellent amplifier for use with a separate preamp processor in home theater applications provided you have the space for 3 or maybe even 4 of these guys. It’s robust enough for most most HT applications and you really can’t go wrong with the price. The only downside of course, is that you would need 3 or 4 Amp100s to power your entire HT system. Considering the price, this is a small sacrifice to the 7 channel units that can cost at least twice as much. So my final conclusion is to go for this amp for rack mounting or go for the Dayton APA150 where space limitations are a factor. You can’t go wrong with either one and the price is right on both!


-50 watts RMS per channel @ 8ohm
-60 watts RMS per channel @ 4ohm
-Bridgeable outputs for 150 watts RMS total power @ 8ohms
-2 stereo inputs with automatic priority override
-A, B, or A+B speaker selector switches
-5-way binding posts
-Frequency response: 20 Hz-20 kHz
-Dimensions: 16-1/2″ W x 2-7/8″ H x 9-1/4″ D

Dayton PM105 Universal Projector Mount Review

Filed in Home Theater Comments Off on Dayton PM105 Universal Projector Mount Review

The Good

Dayton Universal Projector MountThe Dayton PM105 Universal Projector mount is an attractive and affordable mount that fits most projectors. At first glance, this projector mount as with all Dayton products that I have tried to date features high quality construction and offers both swiveling, tilt and yaw capabilities. Another cool feature is the separately available extension which works great on high vaulted ceilings or if you have an obstruction in the projection path. Installation is a breeze and  can be installed utilizing just one ceiling joist for bolting. It’s easiest to mount the base, followed by the projector attachment. It took me less than 30 minutes to have it up and running.

The Bad

There is much to like about this projector (especially the price). That being said, it does have 1 critical issue – and that is that once adjusted, the adjustments cannot be locked into place. While this makes adjusting it quite easy, after a while gravity works its magic and depending on your projector’s center of gravity, the mount will tend to self center. This causes your projector to get out of alignment with the screen. With my projector, it tended to point down and tilt so the image which would cause the image to be off center on the screen.  By the way, none of the screws in the picture are actually used for the adjustment as the whole thing adjusts on the ball joint you see where the downpipe attaches to the mount part. Another thing that causes it to get out of alignment is heavy bass if you have a good subwoofer. Because of this flaw, I cannot recommend this projector to most people because the lack of locking capabilities will drive you mad every time you have to readjust it. This was really disappointing because I really liked the quality and looks. In the end, I had to get a more expensive Sanus Unit so I would recommend you skip this mount and look into some of the Sanus units offered by Parts Express.

Parts Express Dayton RSS390HF-4 15″ Reference Home Theater Subwoofer Review

Filed in Uncategorized Comments Off on Parts Express Dayton RSS390HF-4 15″ Reference Home Theater Subwoofer Review

If you are in the market for an affordable yet high quality 15″ subwoofer for your next DIY project, then look no further than the Dayton Reference 15″ subwoofer. While Dayton may not be a household name, they produce some of the best affordable speakers, subs and amplifiers on the market. This sub is perfect for the DIYer looking to get extra clean and extremely low bass yet has the space for a large cabinet. With a 4.5 to 5 cubic foot cabinet, this sub is more than capable at producing sub 20 hz frequencies that can that can rival $1000+ commercial subwoofer systems. This sub makes the perfect centerpiece to any high quality, high output home theater system and you will be hard pressed at finding anything else like it at this price.

Build Quality

To be honest, this is one of the highest quality subs I have seen to date. While I didn’t have a chance to weigh it, this thing easily weighs in excess of 20-30 pounds. The cone is very high quality and very attractive. The rubber surround is extremely heavy duty and very durable. The basket is a first rate heavy duty cast piece. The sub features heavy duty push type gold connectors so no soldering or crimp style connectors needed here. Simply push the connector open and slide the speaker wire in. All in all, everything on this sub screams high quality. There is not a single part I can point out as being cheap in any way. Build quality is a perfect 5/5. Click Here for Additional Information on this subwoofer


Specs on this sub are very impressive and easy to work with. The sub will work in both ported and sealed cabinets so any DIYer can easily build an enclosure to get massive amounts of bass. This sub can also be used in an existing enclosure provided it is large enough. Specs feature:

-500 watts RMS and 800 watts MAX for high output
-Frequency response of 18-90 hz.
-FS of 18 hz for extra low frequency reproduction
-14mm XMax for high excursion
-2.5″ voice coil diameter
-4ohms impedance for getting the most out of your amplifier
-150oz magnet
Click Here for more Specs

I would say the specs on this sub are easily a 5 out 5 which makes it easy to build an enclosure for provided you have the space for a large cabinet.

Sound Quality

Sound quality is where the RSS390HF-4 really shines. I have mine in a 5 cubic foot (approx) ported enclosure using the Dayton HPSA500 500W Subwoofer Amplifier and this thing really rocks. It easily produces sub 20 hz frequencies. I have had every thing from 8″, 10″ and 12″ subs in all different types of enclosures and this 15″ in a ported enclosure produces some of the lowest, cleanest bass notes I have ever heard, hands down. I mainly use mine for home theater purposes and after building the cabinet and getting it all hooked up, I went back and watched some of my older movies , I heard (more like felt) notes I never even knew were there. I will post the plans and specs for my easy to build enclosure later for those interested in building your own. One of my favorite bass tracks is on the Flight of the Phoenix remake. The first scene where the plane is flying and about to land is simply amazing. It must be heard to be believed. All I can say is, you won’t hear anything like it from any subwoofer south of $1000 and you definitely will not hear anything like it at your local Best Buy. Once you hear this subwoofer you will be amazed at what you have been missing in your movie watching. I rate the sound quality of this sub a perfect 5/5. Click Here for Additional Information on this subwoofer

Overall Impressions

My overall impressions are that this is basically the perfect home theater sub for the DIYer wanting $2000 worth of sound quality at a quarter of the price. It produces some ultra low clean bass and will work in a variety of both sealed and ported enclosures provided they are large enough. About the only downside on this sub is the fact that you have to build or use a rather large enclosure to experience the extreme low frequencies. If you have the room though, the Dayton Reference 15″ subwoofer is probably your best choice. I give it a perfect 5/5 and would even consider any other subwoofer at this price point.

Best Home Theater Speaker System Packages with Sub Under $200

Filed in Home Theater Comments Off on Best Home Theater Speaker System Packages with Sub Under $200

I am all about building your own speakers, but I understand not every one can or wants to do that. So where do you find the best Home Theater package for not a whole lot of money? I could tell you to run down to your local Best Buy and pick one up, but to be honest, that is the worst and last place your should ever buy one. To put it bluntly, they have the best selection of over priced junk ever! Unless you have $400 to plunk down on an overpriced system, then the place to go is Parts Express. They have 3 great Home Theater Speaker systems ranging from $218-$168. Ordinarily, when you systems at this low price, you would expect to get tiny little plastic speakers and a weak no bass having subwoofer. That is not the case with the Dayton Systems from Parts Express since their smallest system comes with an 8″ sub and the largest with a 12″. Check out these systems:

Design Goals

My goal in designing a cabinet for the Dayton Reference RSS390HF-4 15″ subwoofer was to achieve sub 20hz bass for my home theater system. I was previously using the Dayto Quatro 12, and while it was a nice performer, it just could not achieve the deep bass I was seeking. Anything above 30-40 hz was great but it had some severe bottoming out in a 2 cubic foot ported enclosure. After reviewing all the available 15s it became clear that the Dayton Reference RSS390HF-4 15″ would be a suitable choice. Not only did it have some nice specs that were easy to work with, it also had a nice affordable price tag. I decided to couple the sub with the Dayton HPSA500 500W Subwoofer Amplifier. While a better choice would have probably been the Dayton HPSA1000 1000W Amp, I decided to got with the Dayton HPSA500 for price reasons as I wanted to keep the costs to a minimum. If you want to keep costs even lower, then the Bash 500W Digital Subwoofer Amplifier would provide the same power as the HPSA500 for about $100 dollars less. While I don’t have direct experience with the Bash amps, they do have some nice user reviews on Parts Express.


The design on this enclosure was pretty straight forward. Since it was going to be a pretty good sized cabinet yet still needed to maintain spousal approval, i went with a rectangular low profile design that when veneered, it could sit next to our couch and look something like a coffee table. After modeling the box in software, I came up with a 7 cubic foot enclosure (after deducting the amplifer and sub displacement), with dual 4″ diameter and 22″ length ports. This gave me an approximate tuning of 18.5 hz which was well within my intended frequency response for the project. The cabinet has the following external dimensions, 17.5″ H X 36″ W X 25″ D. I will admit that the cabinet is rather large but if you want this kind of bass without spending a ton of money on a sub then you have no other choice


The build was straight forward and easy. I wanted to keep it as simple as possible in order to expedite the build process. This enclosure is quite easy to pull off even for the most novice DIY speaker builder. Since it is a simple rectangle, as most sub enclosures are, it makes for an easy build. I used MDF purchased at the local Home Depot. I like to use the precut 2’x4′ MDF panels. This makes for easy maneuvering when cutting boards to size as well as transporting them from the store to your home. While a table saw is the easiest way, you can also either have your local Home Depot or Lowes simply cut the panels to size or you can use a circular saw. Using a circular saw is a bit more challenging as far as getting your pieces all a consistent length as well as achieving a straight cut but it can be accomplished by using guides and/or a router. I will post some circular saw speaker building tips at a later date.


Construction was pretty straight forward, nothing special since it’s just a rectangle. Once the pieces were all cut to size, it was assembled using 1.5″ sheet rock screws and wood glue. For a better finish, I like making the panels that make up the outside part of the butt joint about 1/4″ oversize. On this box it would be the top, bottom and the sides. This allows me to use a flush trim bit on a router for a perfectly flush joints once the entire enclosure is assembled. It is important that all screw holes be pre drilled so that the MDF does not split. Wood glue is also an absolute must for ultimate strength. Another absolute must on an enclosure of this size and type is internal bracing. I accomplished this by cutting a third panel of MDF then cutting a hole in the center (see plans). This piece was then installed at around the middle of the enclosure, screwed and wood glued to the 4 sides. You could do 2 such panels glued together for added strength but the one does the job. Since the joints need to be caulked, I assemble all pieces but one (either the top or bottom) so that you can easily access all inside joints with a caulking gun. I like to use “painters caulk” for this.

After caulking, attach the last piece. The remaining joints can be caulked through the woofer, amp and port cut outs. Once the enclosure was fully assembled, I proceeded to make all of the cutouts, I prefer to do this as the final step because I find it easier. You could opt to make the cutouts after cutting the panels . The woofer and port locations are on the plans. I left out the amp cut out from the plans because this will be personal preference. I placed mine on the side panel closest to the sub. In hind site, the side panel opposite the sub would have been better for concealment purposes. You could also do it on the rear panel right behind the sub as well. For ports, I used the Parts Express Create-Your-Own Flared Port Tube System which consist of an inside flair, outside flair and port tube. You simply cut the port tube to length , apply some epoxy/gorilla glue/PVC cement to the port tube ends and attach the flairs. I went with this port system instead of 4″ PVC to reduce port noise. If you decide to go with the Parts Express port system, you will need 2 4″ inside flairs, 2 4″ outside flairs, 3 port tubes and 2 couplers. I should note that the ports are a bit pricey but they look a whole lot better than white PVC and the flairs help minimize port noise. You can simply use 4″ PVC to reduce costs, note that the flairs do not work on standard PVC pipes because the outside diameters are different. This enclosure uses 2 4″ ports 22″ in length. Below are the plans for this build. Click the image to enlarge.


Once the wood glue was dried, I gave the entire thing a quick sanding. This is where routing your joints flush pays off. If you don’t have a router and plan on veneering, then you should sand all the joints flush. Once you have all your joints flush, you can finish the box to your preference. I plan on veneering mine but haven’t done so yet. Once you have it all done, install your sub, ports and amp. Be sure to use gasketing for your sub and amp, I recommend the Parts Express gasketing tape. I completed the cabinet by installing rubber cabinet feet, I used the Parts Express rubber cabinet feet.

Listening Impressions

Once I got everything hooked up, I went through my collection of movies with heavy bass tracks. One of my favorites is the remake of Flight of the Phoenix, the start of the movie has a VERY heavy bass track that starts with a plane flying through the sky and coming in for a landing. . All I can say is WOW! The bass coming out of this is amazing! I was hearing (rather feeling) frequencies I had never heard. I went through some other heavy bass track movies and was hearing and feeling frequencies that simply were not present on my previous sub. While I do not have any measuring equipment, the bass was the lowest I have ever heard. Not only is the bass very deep, but it is quite loud and more than enough to rattle your walls. You simply are not going to hear or feel anything like it at Best Buy. I would say that the frequency response rivals that of some $1000+ subwoofer systems I have heard during my time working at a high end AV store. Best of all you can experience this for less than half the price! I’m not going to tell you that this is the best sub system ever or that it is the best design ever but the bass will more than impress and amaze you if you have never experienced sub 20hz bass before.

Enclosure Design

The enclosure is a down firing vented 1.5 cubic foot design. It uses 4 1 1/2″ ports tuned to about 40Hz. Dimensions were kept small so that it could be used in compact spaces, it measures approximately 16″x16″x16″. One of the great things about DIY is that you can play around with the dimensions and port sizing for lower tuning and lower bass without having to spend extra money. So if you wanted more output at 35hz region you could increase the volume of the enclosure to 2.00 cubic feet by simply making it 2″ taller than the plans specify and keeping the ports the same length. In any case, the choice is up to you, I personally like deeper bass so I would go with the 2.00 cubic foot version.
