Description

This is a similar working and sounding 6th order bandpass box like in my previous project - those tiny differences at Vbs and Fbs (low-chamber: smaller Vb/higher Fb, high-chamber: bigger Vb/lower Fb) at these aspects are almost not noticable comparing it to the box in my previous project. Still matching the needs on outer dimensions, just not all port parts are identical. The reason why I made this project is to make bigger distance between the high-chamber's port and the woofer to reduce the distortion.

Description

This 6th order bandpass box for this woofer is the loudest at low Hzs all of those boxes which have identical all port parts (in both chambers) + matching the needs on max outer dimensions (900x300x250 mm) + matching the needs on working and sounding: ideal power handling / reach but not overpass Xmax down to high 20ish Hzs, acceptable vent air velocity and group delay at 20 and higher Hzs, ideal linearity around / below the low-chamber's Fb on amp. resp. and SPL graphs using +3dB=60Hz/12dB cabin gain.

Enclosure

BP6, Vbfront: 8.6l, Fbfront: 34.8Hz, Vbrear: 1.9l, Fbrear: 187.1Hz
