Thanks John. One of the systems I was thinking of building is the SEAS KINGRO4Y MK3 which is also a 3 way with a coax mid/tweeter. Although I'd redesign the enclosure for better vibration control(keeping frontal dimensions the same) and getting the amp out of the box to minimize microphonic affects on the amp.
I investigated further and they claim Valchromat is 30 % stiffer than MDF but more importantly 3 times as stiff. If true it sounds like a great material especially since it comes in multiple colors that run through the material making finishing simple. I wonder how using it with constrained layer damping would work.
Plus their own speakers are not awesomely priced and measure superbly. I'd love to hear a set. My slight worry is wile they are dead nuts flat, that can lead to brightness as the dispersion narrows but the power response stays relatively level. That's why a flat response but with the flat line slopping slightly can sound more balanced.

  Did you mean "Heavier"?
  
  I would not bother with CLD in the sense of, say, fusing two 3/8ths inch Valchro boards together with Saint-Gobain Green Glue.
  
  GR Research's product to line the inside of enclosures has a CLD aspect.
  
  My guess is that Zinnser's Spray Shellac would give it a nice matte finish.

    Sorry my brain wandered. It's 30% denser.

      Sorry, brain fade. It's 30% denser.
      
      And I personally would gild the lily and also use constrained layer damping. But I now recall the Ex Machina owner implied it's better damped than MDF claimimg that instead of wood dust, Valchromat uses string material and the strings vibrate and that shaking improves damping over MDF.
