November 18, 2010 DIY subwoofer for home theater.

I wanted a great sounding subwoofer for my home theater setup but I was never pleased with anything that I saw in the stores so I decided to go the DIY route. At first I was going to have a cabinet maker build me a box but when I found out how much that was going to cost I decided to just use a car/van box and save the extra cash to get a good amplifier.

The 2SL12-2.7 (Black) is well made and has worked perfectly with a pair of Peerless 830952 for three years now. The recessed ends add strength to the box and make it easy to move. The money I saved by buying a 2SL12-2.7 from Sonic Electronix.com got me a B&K ST-2140 amplifier on eBay. I also added a set of carpet casters from H*** D***** to make it easy to move around and help with decoupling. I only wish there was an option to get the box terminals on the back instead of the sides.
