I'd always figured that granite enclosures would rule audio-wise - they'd
look nice too. All other things being equal, I suspect that the higher the
density of the enclosure material, the better the sound quality.

Mebbe but it's not so much the density as the damping. Some of the
best enclosures were made of Aerolam damped with bituminous felt.
Many modern enclosures are made of synthetic laminates with internal
damping layers.

One might check the archives of speaker reviews at www.stereophile.com
(shameless plug) to see the bench tests of speaker enclosure
resonances. Fewer and shorter is better.
