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!
