Jon, Would using diffusors (with absorbant properties as well) have a better effect than just the fiberglass panels that you describe? After reading through The Master Handbook of Acoustics, I am very excited about the concept of diffusors. I have no asthetic concerns (bachelor pad) and am interested in getting the best performance.

I am currently envisioning an absorband diffosor if this design:

purchase Owens-Corning 703 board or equiv. Critically measure the thickness of the panel. Use this thickness as my well width for devising a primitive root sequence. (have yet to determine the well divider material...any suggestions?) Use the sequence to create onde dimensional wall panel diffusors. I will make each diffusor around a target frequency similar to Steve Dekert's SWAL and DWAL (www.decware.com).

My hypothesis is that by using the 709 material from the "bottom" of each well to the back of the diffusor will create an absorbant property (proportional the the specific thickness at that point of course).

As you can tell, I have left out a lot of details, as I am still in the formulation stage. I am wondering what you think of this aproach. BTW, the diffusors could also be placed on cieling at reflection points.

Thanks for your help in advance:
-Juan
