Hey guys, was just wondering how you feel about using bituminous substances (Dynamat comes to mind) to dampen loudspeakers against cabinet vibration. I think Spendor uses it, but I am not sure.

All kinds of stuff can be used to dampen loudspeakers.
It is all about achieving the desired cost/effect.

A bunch of DIYers use roofing shingles to line the inner walls and I personally have used non-drying clay before as well as Aperiodic membrane baffles. I use my father's ability to source architectual products used to control sound and vibrations. Like Curtis said, there is a bunch of products available that one may never consider or even know that it could be used for loudspeakers.
Speaking about enclosures, when I knuckle knocked the 340 I would swear that was HDF. How in the world is that so rigid :D

Great engineering/bracing.
Have you tried the knuckle test on a Sierra? :D

I did yours so gently when you allowed me to audition a couple years back. I didn't want you to back hand me, so gently I did before we listened.
