I think I got some people's attention by writing that Actually my question does relate to bose. I have a set of bose acoustimass series speakers . And yes, i am aware of the saying of bose and how you all despise bose. But I'm stuck with em cuz I didn't by them. When listenting to my HT I notice bass isn't that prevalent. My question is if I should get a sub woofer to handle bass? I like listening to music with bass in it, and I just want my room to shake. It doesn't now unless I crank the volume. I'm looking to spend about 300-400. I'm not sure if this number is low but I already have two bass modules. Or whatever they call them. If so, which one should i get? I went down to my local electronics retailer and found this one called Qwest. Anyone heard of it?? Thanks, everyone!
