Folks: I currently have a HSU VTF2 that in my small media room (13' X 11') works fine for movies and music. However, I am moving to a house with a much larger space - the media room is 30' X 17' - and I have upgraded my L & R main speakers from box speakers to Magnepan MG 1.6QRs driven by a B&K 4420 amp. My concerns are filling up the larger room with bass and having a subwoofer that is "quick" enough for the Maggies (for music). So, my strategy has two possibilities: One, get another HSU, probably the VTF3-MK2 and between the two of them, I should be fine for filling up the room with bass but will these subwoofers be quick enough for the Maggies? I don't know... Two, get another subwoofer that addresses both concerns and sell my current VTF2. One is easy as long as I can get some confirmation that it will address both concerns; Two is more problematic - which subwoofer? The SVS PB12-Plus/2 looks good for filling up the room but can 12" speakers be quick enough for the Maggies? Please advise. Thanks.
