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.

Peter is absolutely correct, maple with a bit of bracing is very non resonant and does a good job... I am actually refinishing the front of my cabinets now in Maple... the problem with maple is that it is tough to stain... that's why you will find it isn't used much.

I haven't done this, but with so many responses, I'll throw it in, maybe someone can try it. For the past several years, I've been thinking of trying small Styrofoam balls, mixed with concrete and epoxy, poured in a mold and sprayed with an automotive finish... Still may try it someday.

I've seen a few concrete enclosures. My thinking has been that the Styrofoam will significantly lighten the concrete while not losing anything in strength. Then I think of stacking different materials... one dampens the next, dampens the next etc...
I believe that the epoxy will be another dampening material and equally strong, the enclosure should be very dense and as well damped as any material out there.
No testing, nothing scientific about it, just a hunch that I'll have to try someday.
