This speaker is a work in progress. I have posted my final revision, but it may still require some minor fitting.

These are small computer speakers that are a modification of an existing “boombox” design. I used the design by Tom Zarbo found here https://www.youtube.com/watch?v=zCrpgpnYlOo and made them into separate speakers.  I used the same box volume, port dimensions, driver, and filter.  The walls are filled with sand and topped with CA glue to keep it in place. Use a layer of thin foam to seal the back to the cabinet.

There are two files for the back. One is solid, and one has a hole if you want to use a terminal cup (260-297) from Parts Express
