PVR Rear 21 inch isobaric subwoofer NOCHTI

Heres a video of the rear 21" Isobaric sub in the private viewing room theater. Each, enclosure has around 1200# of concrete in them and they have zero resonance. In some spots the walls were over 3" thick. The subs are seperately EQ'd with a 1/3 octave EQ (DBX 2232) to rear to handle 40hz and below and the front 21" effectively handles up to 100hz. The subs are crossed over using my Theta Digital Casa Nova pre-amps "phase perfect" crossover at 40hz. The 5.25" mid woofers see a 24db slope and the subs see a 6db slope. By basically using the mids full range with a subsonic filter at 40hz the 21" woofers never announced them selves untill needed. Never boomy or overblown untill and explosion rocks you or a Bass pedal tone throbs to life. Using two QSC USA-1310 amps, each sub received 1200watts and produced 120db+ down to 16hz in the listining room when sealed. Stunning, musical bass!
