Sonus Faber uses solid hardwood beginning with their Olympica line of speakers.

So, Peter- no solid hardwoods? Yes; voidless plywood(ie:
Birch) has always been a good(and expensive) option, for
speaker cabinetry. Probably the most expensive component of
any of Klipsch's early systems. In the 80's; I was using,
"47lb Industrial Roseboard," which was the highest density
fiberboard available. I suppose that would be the
equivalent
of today's, "HDF." None of my home systems were
as large as yours, hence; baffleboards didn't need that kind
of thickness to combat resonances. You guys do some beautiful
veneering. I used to order mine from Bob Morgan.

I don't know the answer to this question, nor do I even have an opinion, but will the B&Ws sound better with a less resonant cabinet or will they just sound a little different?

Daedulus Audio makes their entire cabinet and baffle from solid hardwoods according to their website.
