Actively bi-amping B&W Matrix 800's

I read somewhere that B&W allows you to Bi-Amp but you still go through one half of a passive Xover...at least you reduce IMD distortion that way but you don't make it a whole lot easier of a load to drive.

Full Actives are possible but are probably best left to be designed properly by the manufacurer besides if you monkey around with the internal guts of the speaker then surely you will affect the resale value (if you are honest about it when/if you come to sell)

The mid and hi pass filter for the B&W Matrix 800 are of very high quality. The mids and highs sound very transparent even when driven passively.
IMHO, the majority of the current drawn from amps goes to the woofers therfore just going active with the 'Bass' is an effective and wise move.

BTW, does KBX have both RCA and balanced in/outputs ?

I have the 800's actively biamped with the KBX. The best improvement that I ever made to my system. I upgraded from the regular 800's. I did the conversion myself using Dan's directions.

Unfortunately, the KBX is no longer made, but you can find used units. I think Krell will make the board for it, but you should ask them.

I have never heard a speaker under $75,000 that bettered my 800's.

Feel free to contact me for any info.
