The DSP sub is two 6.5 woofers in a sealed box, firing into a 3mm thick ABS plastic panel with no grille. The crossover is 80 Hz and down, and the resonant frequency of the 6.5 woofers is 80 Hz.

Basically, it's pathetic.

And MB Quart does NOT make great acoustic speakers, and JL Audio is most emphatically NOT the best in amps or subs. Competent. Not "the best".
