Best products for baffle material s ?

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.

Mr C- Thank you. Never heard of that company. I'd be interested in comparing the sounds of the various species of wood they use(same models/internals/drivers, but different woods).

Thanks Zd. I think the screws on 'virtually' all cabinets loosen over time due to the laws of physics. I am a fastidious about maintaining screw tightness on my cabinets and drivers as I also own a pair of heavily modified JBL 250Ti"s which have a 14 inch bass driver with an ~ 22 lb magnet that has real propulsive force! I'm with you that loose drivers means loose sound. (I am very fussy about stringed classical instruments clarity). On my B&W Concept 90 CM1's one must tighten the entire, unique, one piece baffle to the box as well as the dome tweeter to the baffle. Both loosen even though obviously they're not played that loud. (Yes I take off the baffle from time to time to check the 4" driver.)
