Description
This is a sealed box for 8 pieces of this woofer which is possible to build / use like a wall even in a normal sized, or smaller car. I added displacement for 6 pieces of braces with a diameter = 50 mm. The box's Vb is the biggest possible Vb which gives the lowest possible F3, it have ideal RMS power handling down to 10 Hz, and 130+ dB SPL down from 41 Hz at a cabin gain like 60 Hz / 12 dB. The group delay is super low as at any other sealed boxes for any woofer - so it have very fast and clear sound.
