I just moved in to a small place that has a cabinet in the corner where I've been told by the wife is the only place a subwoofer can/will be placed. Either something goes in there, or no sub. I'm easy either way, and right now I'm leaning towards no sub, but thought I'd fire this out there.
The cabinet (I know, bad idea for a sub; work with me here) is 9 5/8" deep, 22" wide, and 12 1/2" high. The last guy must have either had a sub in there, or took the door off (not an option for me I've been told), because there is a power jack and a sub cable. There are 3x in-wall 6 1/2" monoprice speakers that I haven't tried out yet, and I'm thinking that an 8" sub probably won't give me that much more than the in wall speakers.
I found one 8" sub that was a 10" cube, and it's soooo close, but no cigar. I'm open to options - a car sub, a tube design, etc. I'm not an audiophile by any means, but wouldn't mind hearing a boom every so often. So, does anything exist that would fit in there that is "ok"? Budget is a consideration - max $500.
