Are exotic speaker cabinet materials overrated?

@pindac   Watching the Youtube video on the 'B&W factory tour' building the 800 series they use their own fabricated version of Panzerholz. Muti layers, pressure,heat. Amazing construction process.

Forming the shape is something special that can't be done using flat panels. Most manufacturers and DIY'ers are restricted to box shapes. Rounded smoother shapes are desirable. For this reason I do find the croncrete speaker a very worthy experiment over the added cost of Panzerholz and shape limitation. Concrete  (or a blend thereof) of might even be superior!

Everything matters in audio. 

@mark200mph how do they resonate when pushed hard with boosted bass?

@gdaddy1 800s still resonate and sound woody when pushed hard.

@foggyus91 all the supposedly inert materials assume recordings are perfect, which they aren't. The treble is rolled off, which is a miscalculation for flat speaker theory and why they sound dull, lifeless with no detail. Additionally, recordings don't capture the full sound, resonance and attack as when instruments are played in the living room. It doesn't make sense to me to reproduce and restore the sound of wood by converting it to concrete or any other material. You have metal domes to reproduce metallic instruments but you still need a wood cabinet to reproduce the sound of wood instruments.

"you still need a wood cabinet to reproduce the sound of wood instruments."

My speakers don't have any wood in them and yet I can still tell the difference between a guitar, violin, etc. 

I push mine with hegel h 30 a mono, mcintosh 2kw with 8kw transients ,krell 700cx 4kw transients and the magico do fine . I guess like jbl these guys have software and engineers that do all the calculas as I hated that class but scored the highest.dad was a nuclear physicists that did operation red wing look that up. I did 4 years of machine shop in highschool.that helps when I have to put ti plates in people's head. Those amps are on the q7 magico there power hungry. Now my focal are wood but thick some of the wood is 3 inch thick and I have many wooden speakers weigh > 500 lbs. Internal bracing.
