whoom instead of BOOM

thanks guys. just to clarify a bit. "whoom" is trying to describe lf passages that are lacking attack. they're loud but have no definition and totally drown out other lf tones during the passage. i'm just wondering, does everyone have a volume point at which their room acoustics and or equipment turn to this type of response, instead of detailed well defined bass?

everyone thank you for your input. i think i may have led us all down the wrong path. 10x18x7 are the exact dimensions of the room, so it is not very big at all. even though a $5000 velodyne dd18 may be a solution it isn't quite my cup of tea. i'd go to a vmps or bag end type. however, i was more wondering if you all knew wether or not, despite decent quality subwoofers, is there a point where they may just get boomy and undefined sounding or is it my room, or are they really not that good. the mirage does sound fantastic at lower volumes. the best i've heard in my limited experience. i am lrking everywhere i know of to try and catch a vmps used for sale. it is tough unting ou there for one on the cheap. i may also go with a clark synthesis. thanks again guys.

HA! very clever mr. bond.
