Hello to all, I have finally received the blessing from the family CFO to update my sub. My sig has the hardware list that I mainly use in this 14 x 24 x 8' finished basement room. The room can be closed off from all others. Use of room is 75% HDTV/DVD and 25% music CD/vinyl. Depending on the mood it be anywhere from 75-100db. Due to dealer choice and budget constraints I am limited to the following 3 subwoofers: one Velodyne DD-12 or one SVS PB12-Plus/2 or 2 HSU VTF3 MK3s (non-turbo). I can not audition any of these except to use the 30-45 days all bets off return on all 3 of these subs. I can't have them here all at once. I guess I am looking for anyone of ya'll that may have been fortunate enough to have heard at least 2 of the 3 to compare the following qualities: HT use to musicallity (is that a word), tight sharp bass vs non-distinct muddled sounds and SPL. 'preciate any insight you may have.
