that's simply economy issue

Heat issue too.
Of course the bass amp have to meet the requirements, but classA is a waste of money and energy.
Just my opinion.

I now use an Aleph60 for driving two parallel scanspeak 21w8555 and I like it a lot
(crossed @ 350Hz)
And remember; no filter(read losses) between speaker and amp.

I'm not disagreeing with you ; just complementing the puzzle .

to each his own .......... my speakers don't need multiamping , same as they don't need more than few W for proper singing

I find the difference between 'normal' speakers and multi-amp really dramatic.
And money and energy are never wasted! They are both just in another place.... ;-)

I agree. Just having gotten MOX II up and running, I can say there is a big difference between bi-wiring a passive XO to a bi-amped active setup.
My monitors sound like towers now. Just huge!

Just a pretext to build more amps.

too much talking, not enough picture posting. there's an off topic meeting of the audio knitters society on the top of the page.

Here is my Balanced F4, I drive a pair of them with a Pumpkin and Impasse the Pumpkin is faster the Impasse is laid back. I have been holding on to a set of SIC JFETS waiting to build J2 clone if it ever comes out, and would like a build a B4 and a pair of OB. Since Mr Pass seems to be holding those designs close to his chest I have had to resort to brewing beer. The wife is much more prettier and the sound system sounds pretty good.

So you confirm that it is, in fact, just an economy issue.
