Default empty b&w 805matrix cab, what to do?

So i got a pair of b&w 805 matrix enclosures for free, no drivers, no xover just the empty shell for the bass/mid driver. its a nice, heavy and wibe dead enclosure.

original driver was a mid/bass 130mm (5.4"), enclosure size 10,5L acording to review on stereophile.
B&W Matrix 805 loudspeaker | Stereophile.com

was thinking of entering the one driver world

What driver availeble in eu would you put in those two boxes? doesnt have to play very loud or very low, will be uses as a bedroom speaker with holfi cd and 45W integrated amp.

price 2 drivers: hmm max 270euro/350usd, less is also good

best regards

bent

165mm (6.5") Kevlar-cone woofer with 3" voice-coil.

I had m805 for many years. Great speakers.
Much better than the later iterations.

thanks for your reply,

hmm refering to original driver? the cutout for flushmounting of the driver is 17cm and the hole is only 14,4cm so a 16,5cm driver woudnt fit

had original m805 ten years ago, and it was a great speaker.

best regards

A new cutout can be made with the usual tools for these tasks if you have them. Going bigger from smaller is easier. A new baffle front can be simply glued in place or used as a guide temporarily. Then use your cutout device whether it be jig saw router or zip tool with cutting blade.

The drivers and crossovers are still available from B&W.
For about $700-800 you could make them whole again.
For ~$500 you could get the woofers, run them full range and save for the rest.

10 1/2 liters. I'd somehow actually measure the volume, i wouldn't take Stereophile's guess as gospel.

From the drivers i am well familiar with a tiny bit big for Alpair 7.3, Fostex FF125wk, CHR70, CHP70 (easy enuff to add some solid fill), a bit small for Alpair 10.2, EL70, CHP70.1, but can all be made to work. TB W5-1611 might work (i haven't looked into boxes for this one yet)

Hi tom,

thanks for your suggestion,

2 tweeters 490usd
2 tweeter housing's ???
bas/midrange drivers ???
xovers

i will ad up to more alot more than 800usd, its a bit more than my 350usd limit .

any suggestions on fullrange drivers that would be worthy of these enclosures?

Hi planet10,

first of, the part of the baffle where i can mount the driver is 22cm(8,6") wide.

second, im looking for something that is easy, so not sure if can be made to work is something i should be after .

The matrix structure makes it very har too measure accurately.
the enclosure with wall thickness(16mm) deducted is 18L, the matrix structure is 6mm thick, some has holes in it, some doesnt and it fills the enclosure...
but youre right, 10,5 does sound a "bit" of

any good suggestions?

best regards

i can only buy the tb driver en eu e-shops(i think)


what can i expect from a fullrange driver this size?

tb- sealed 11L, qtc 0.65, f0 apr.200 f3 apr 100hz f5 80hz almost "same" in 15L.

ported: only way to get it "flat" before roll of is to tune it below its fs, thats no good right?

best regard and sorry fore the newbee questions
