Beautiful Vicoustic's flagship Wavewood panels for room tretment. Anyone?

 Another vote for Vicoustics. They transformed my room from
average to outstanding. They give you the option of using
their computer software to map the room. I preferred that
method versus guessing as they have specific measured areas
to place each specific panel. I heard the biggest
improvement with the diffusion/absorption panels on the
ceiling which usually gets overlooked.

  I use a product from Vicoustic, Wave Wood. It is similar to the new GIK diffusort panel, the Wave Wood is wood over absorbers, and serves as both a diffusor and smaller absorber. All I can say, after may years of experimentation, this is the best combination that works for me. Of course, some environments will require a lot more absorption than others and integrating diffusors into those types of room may be challenging. I would strike a balance between the absorbers and diffusors. In most rooms I have treated, I have had positive results using this formula.

Have you tried RPG Expo ? 

This type of panel based on a perforation pattern is a tuned absorptive product.RPG Expo is design around optimal binary sequences – these begin to scatter frequencies above ~4KHz.RPG is the only company that has a method behind this type of digital surface approach.With the right mounting condition they are excellent for the right application.
