Subwoofer for Beginner


I thought I'd experiment with a subwoofer with my Audience ClairAudient 2+2s. My room is an odd shape and bass is getting sucked out around a room divider that holds our TV. Can someone recommend a low cost small footprint (our place is small) subwoofer that would give me a taste of what a subwoofer can do? I want to see how it can work before I drop a bunch of money.

Just a word of caution ... subs are speakers too! Don't cheap out too much. Matching a $200 fart thumper with your $5,000 main speakers might just work out fine, but if not, I'd blame the pedigree or implementation more than the concept. (For all of those who spent $200 or less on their subs which work wonderfully for them, please do not take offense. Not all $200 subs are made the same. I am not inferring about any specific sub mentioned in this thread.)
If not confident in your purchase, buy used so you can re-sell at little/no loss if you do not like.
I'm with Wolf and love REL subs. Find. b2 for under $1200 and experience what a sub can do for you. You'll be able to sell it for what you paid for it.
I have a Martin Logan Dynamo 700 that packs a pretty solid punch for its size and it wasn't too hard on the pocketbook. REL has some small footprint subwoofers that are generally well received.
Okay, so now I understand better why sometimes you need a sub. If you' e landed a pair of speakers that have incredible mids and highs which you are not willing to give up, but no deep bass, well....here we are.

Keep us posted about which sub you go with!
