Hello,
Look at this board. It is some kind of epoxy, carbon fiber resin construction. 1/2 inch think. Very heavy. I was wondering if this could make for a good compact speaker cabinet? Anyone have any idea as to its resonance characteristics.
Also...this material is used to prohibit bullets!
I'm not sure...but it may also have Kevlar in it.

If it feels solid it's probably fine. May be hard to saw though.
Its definitely hard to saw...but doable. Is there a way to measure the resonance?

Yes, but if you ask you probably haven't got the equipment necessary to do it 🙂
I wouldn't worry about the resonance, knock it with your knuckles and see how dead it seems.

A very interesting material. Do you have a link to a source?
Stiff is good. Light & stiff is better. Every panel will resonate. What you want is a panel that resonates at a high frequency (where it is less likely to be excited)
Some background in this thread.

You aren't looking for dead. You are listening for high-pitched resonance and if it dies quickly that is better. A dead, low frequency thunk is a bad sign.

As i imagine a tink, tink, that is good. HF and fast decay (ie high internal damping)
What size are the panels?
