The living room sub is great I tried it in the bedroom though & that was the problem, it was too loud acousticly & there really wasn't anything I could do but try it with lower volume which made it ineffective That sub was around 450 watts 8" So I went back to use my 8: 125 watts Acoustic Research Sub whose sound blends in the room & is fine for DVDs & TV but just so so for CDs. I'll see what happens with the M&K K-9 sub I'm getting- the price was right, it was $185 or so with shipping & sells new for $500 & is also 8" 125 watts & the aurelex carpeted isolation riser for a sub. I'll also probably try my living room sub on the isolation riser in the bedroom & see if it makes it any better.
