heres an elegant approach..
US7270215B2 - Loudspeaker enclosure with damping material laminated within internal shearing brace
- Google Patents
Looks like it expired so I guess you can play
IMO it should be quite effective if done right. Sheer mode damping taken advantage of.

Yeah. I had a look at their patent. Good way to include cld in bracing.
While thinking about new ways to dampen my loudspeakers I realized I had come up with what is known as Negative Stiffness Mechanisms (NSM). This could be applied to Driver decoupling from cabinet. For whole speaker cabinet design I think it would be possible but a lot more trickier. I came up with constraining walls in a state of buckle (when they are in negative stiffness state). A simple S shaped thin wall of metal that wants to bounce back to 2 possible curved stable forms. I wonder if you can tune such a system to damp from say 100 to 400 hz which would be ideal for a 2 way system where the fundamental frequency lies in this region.
