Description

In this project I designed 2 relatively compact boxes for this woofer: 1 closed, 1 vented. My rules for closed box: ideal RMS power handling down to 10Hz, and reach but not overpass the Xmax. For vented box: at 60Hz/12dB cabin gain no double peak on amp. resp. while increasing the Hz, ideal RMS power handling + acceptable group delay (less or equal to the half of actual Hz's time in ms) down to 20Hz, low vent air velocity. On 3D you can see the louder (vented) box.

Enclosure

Vented, Vb: 30.5l, Fb: 24.3Hz
