Building a Subwoofer

Here's how this all came about. There's a room on campus that is a performance space. The P.A. system that is flown is basically a pair of Yamaha club speakers. Nothing fancy, durable and decent for vocals when a band shows up.

Keyword; Band. However the DJ's have been feeling a little light in the low end, when the bass drops.. these poor Yamahas can't handle it. They weren't intended too. We need some bottom, we need a subwoofer.

Ok we could go the easy route and JUST BUY ONE. But where's the fun in that?! More fun to build one! So here we go!

Our basic dimensions were for two 10" subs mounted in the box, 3" of gap on each side, a box depth of 10" and the whole thing would be 32" long.

1 Crown XLS 1000 amp
1 Sheet of 3/4" MDF
1 small roll of hardware cloth
Speaker wire
Glue
Screws
Sandpaper
Primer 
Paint

Tools:
Table saw
