Best products for baffle material s ?


Looking for the "best" combination of materials. Building new boxes for my B&W CM1 bookshelfs as I can feel vibration on the baffle and sides, with classical music, quartet, at even very modest volume. These are very small 2 ways - so I can afford to go "all-out" on the boxes. High mass, inert, shaped baffle to minimize diffraction, interior design to break up waves. I'm considering only products that can be "woodworked". More detail later. Thanks.

The front baffles on most of these are made form laminated hardwood, most from 1.625 to 2.125" in thickness. The back cabinets are made from MDF which is veneered then finished or finished in automotive paints.

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.
