One of the things that should be investigated in conjunction with higher
order Ambisonics material would be to "fade down" the higher order
components as the frequency drops, thus spreading the bass over more
speakers, reducing the strain on the individual speakers whilst maintaining
the spectral balance - hey, wasn't that Richard Lee's Powered Integrated
Sub concept from several years ago?? Doesn't help with first order materiel
but....
