I recently bought some m22ti's and am quite happy with them. Now I want to buy a subwoofer. I'm trying to decide between the ep-125 or ep-175. I have an Adcom GFA 535 stereo amp. My room is about 16 x 20 ft. I like the idea of the smaller footprint ep-125 and don't need a lot of volume, but I've read some things on the internet that aren't that favorable... Any thoughts?
