    Default Using Bituminous Material (such as Dynamat) to Dampen Loudspeakers

    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

    Great engineering/bracing.

    Have you tried the knuckle test on a Sierra?

    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.
