you mean pure/raw wood boards ??
It is overkill for a speaker cabinet IMHO
Moreover, pure wood boards are not adapted for speaker building because their properties change with time due to the water remaining inside them, a problem you won't get (or you are not likely to get in "normal" conditions) with MDF or plywood board.

Ooops sorry I don't have the english skill necessary to talk about this stuff 😀 I should have searched a translation before
Never tried this so I cannot say anything.
It should be OK if you find thick enough boards, as it has a well damped sound when you knock on it.
But maybe the hardest part would be building a neat cabinet with that. 🙄 Good luck !
Greets !
It's very stiff, (good 🙂 ), but very porous to air, (bad 🙁 ). If you laid it up with another material it should work well.
I'm not sure how stiff it is... Try picking up a sheet of it-its as flexible as plywood I'd say. The fibers make it similar to ferrocement which can be surprisingly flexible. It may still be a good material, but people tend to assume: cement= stiff
Chronic resonance at low[ish] frequencies alone. Only suitable for killing MDF resonances as a compound panel as far as I can see (I believe Bob Brines does this, or something similar to good effect)
The stuff, (known as blueboard in the building trade), we get over here in the UK, is usually used as tile backing and is very stiff, much more so than plywood.
Thanks for the replys.
I used the wonderboard under ceramic tile in my house and was courious how the 1/2 inch thick board would work with the fostex 108s
One problem would be building the cabinet. Connecting the boards to each other.
I just wondered if anyone had tryed to use the concrete boards before for cabinets?
Thanks again.

No idea about the attachment issue I'm afraid. Some sort of glue or bonding agent, or even a small amount of cement might be the way forward. Then again, audiophiles in the great mono era of the 1950s used to build H-U-G-E concrete enclosures for a Tannoy 15" DC Silver, so it's not all bad.
As regards stiffness though, something to think about: remember that stiffness in speaker cabinets is not everything. Think of them like a sword -what is very hard is not always much use, because it has resonance problems. A compound structure with MDF and this stuff, as Bob Brines uses is good. Alone -I wouldn't bother.
