How cheap?
Based on an article I read somewhere, I bought a cheapie KLH 10" powered sub at Costco for $69. Then I bought a concrete stepping stone to place it on. Then I popped it open and stuffed in more insulation material (foam). Man, what a difference!
One of the problems with cheap subs is they have lousy acoustics, that is, they don't push the sound out, rather it just kinda falls out. With the foam and concrete slab, the sound is forced into the room.
I'm not saying it's going to match the response, timber, tone, etc, of a $600 sub, but heck, it was only $69 plus $4 for the stepping stone. I used foam from a packing crate at work. Man am I cheap or what?
(Actually my wife wouldn't let me spend more, she wanted to buy food or something silly like that...imagine that!)
