I have with me is a brand new pioneer pdp-5080hd. I saw on the back it has a subwoofer output. I have looked at lot of reviews of subwoofers online and many person says jbl is probably the best bu I am still confused. My living room is 30 x 20. Which subwoofer do you guys think would be best? I really liked the small SB12 Plus but im not sure if thats big enough for my living room. What do you guys suggest? Pls help
