forgive me for budding in,
the bass of the vsm is partially controlled by the bandpass filtration in the bam. since the woofer's fs is 28 hz and x-mechanical is one full inch, there is a great and obvious potential to decrease power handling/increase distortion through excessive cone excursions. filtering out of band energy decreases im distortion in the mids while reducing 2nd and 3rd order harmonic distortion by keeping the driver in linear drive longer and at higher levels. the latter distortion sounds like boomy bass.
