The Battle between Stiffness And Damping Of The Speaker Enclosures!

And what will we do when we get this super stiff highly damped speaker? Put it on springs.

As the chart shows plywood has a stiffness of 8 and diamond has the highest at 1050. 

The perfect speaker would therefore be made of diamond. Why hasn't anybody done it? Or have they? 

Here's some feedback on the Aequo Audio Ensis speakers!

Well you would need diamonds bigger than the Hope Diamond  but you could ask Howard Rather from Uncut Gems to get some ...Oh wait he's dead.

Some say these Volya Bouquet Loudspeakers could be one of the very best on the market right now.. 
 
I've never heard these speakers yet but a friend of mine up north replaced his big Soundlabs with these and never looked back!  These are way out of my price range though!
