Does anyone know the crossover frequencies for these speakers. I meant the matrix 804

Service manual, owner's manual and brochure- no XO points data.
Let me guess. With those XO parts maybe 200 Hz and 3,5 kHz.

Listed on the spec list for current Diamond series, the XO for 804 are 350Hz & 4KHz, and googling around would quickly find a review from 2000 (long before diamond tweeters) with the same figures.
matrix 804
It's amazing that B&W never listed the xover frequencies. The reason I'm interested is that I want to build outboard xovers for my B&W P6 speakers based on the matrix xover design.
The P6 xover frequencies are listed on the B&W site as 150 and 3000. However all the P6 xover components are squeezed together on the inside back surface of of the binding post plate while the matrix xovers look more thoughtfully designed.
I was thinking of reproducing the matrix 804 xovers, in outboard enclosures, with better quality components. The only difference between matrix 804 and P6 kevlar and cobex drivers are the coil and cone part numbers. The size and all other components are the same. All thoughts on this will be greatly appreciated.

Based on 4.7uF/0.15mH/10uF tweeter filter, about 3.5 kHz for the tweeter crossover. Bass is whatever it is. It's a 2.5 way. so maybe 150Hz.

Bit hard to say how different the drivers are.

Interesting. The P6 was also called 2.5 way and, based on your 150Hz guess for the matrix804, that also matches the b&w specified P6 bass xover. I'm thinking the matrix xover, in outboard enclosures allowing ideal spacing/positioning of components, may work with the P6. I removed the P6 xovers last night and all caps are cheap electrolytic and poorly spaced and positioned inductors, two with iron cores, and all with small diameter wire.

Hi system7,
Good guess. I contacted B&W support and they verified the xover frequencies as 150Hz and 3kHz. That makes me believe it will work with the P6s. Thanks for all your replies.
