What You Can Do With a 21.25" Cube
This is a sub I built for a friend from work.
It's a 15" TC Sounds TC-3000 subwoofer in a 100L sealed enclosure with Parts
Express's HPSA1000 plate amp. The box is built from 3/4" MDF and covered
in 1/4" oak veneer. There's 4" of R-11 fiberglass insulation lining the
sides and bottom of the cabinet. The front baffle is 1.75" thick and the
overall box is heavily braced with window-type bracing and cross bracing using
3/4" MDF. The target Qtc for this design is around 0.65.
For now I'm just going to put up some build
pics. I'll try and write something up later when I get a chance.
