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.
