To follow-up & clarify on some of my other questions on this topic, I basically am looking to replace my second subwoofer (Acoustic Research ARS108 120 Watts 8" Sub) in my bedroom & I'm looking for a sub that will give deep sound but not huge vibrations , as I don't want my walls to shake or boom. My regular Orb Audio Supereight Sub which I use in my open living room is great & is around 400 Watts or so but is too loud in a closed confined medium sized room. The Acoustic Research Sub actually is fine for DVDS & CD's as its not an overbearing sound & does not cause my walls to shake or anything, but when I play CD's, I'd like a better sub sound. I live in an apartment with the manager below which is why I definately do not want this sub to make the floor shake.

Someone suggested Mirage Omni & it sounded good till I read about it being able to make the walls shake. Well I don't want the walls to shake. Maybe all subs can make the walls shake so I'm over reacting.

In short if anyone knows of any 8" subs that give a nice, smooth, deep bass but aren't overbearing & powerful for both CD's & DVDs, please make me any recommendations.
My receiver is 735 watts. Thanks for any input.
