I have a small little entertainment room, aka my room. I have a 5.1 sony receiver, 50 inch plasma tv, 4 sony bookshelf speakers, and at the moment I lack a center channel and subwoofer. The receiver I received as a gift and its a bit old, my sound is good enough for me and by all means it isnt the best, an audiophile may listen to it and puke, but I love it for my own little deal. Just picked up a new job, and getting my paycheck today and wanting to pick up a sub to add to my system, the thing is that the receiver only has a RCA jack for sub output. Looking for up to $250, an everyday sub, I Dont need to crack my walls as I just fixed them. I listen and play movies, rap, rock, techno basically everything. Iv been interested in BIC americas v1220 and f12, they seem to be a good deal for the money but I can't really say as I'v never listened to them. I need something for a 18x18 room thats nice and pretty clean. If it cant make the windows rattle I dont want it. I want to be able to feel the hard earned money haha literally. I can possibly wait for my next paycheck to lift my price to about 400 but im not sure if its really worth it. Any opinions would be great and thanks.
