I would think the heaviest ones would have the best acoustic properties, and they may be a more cost effective solution than velour. By the way, I found an excellent resource on rooms and acoustics: Everest and Pohlmann, "Master Handbook of Acoustics", 6th Ed., available at Amazon. There is data on the actual absorption characteristics of different curtains, along with a zillion other things. The chapter on Comb Filtering is worth the price of the book. Comb filtering will also affect imaging.......Charlie

You're welcome, Charlie. And thank you for the resource on rooms and acoustics information. At the moment, the idea of further room treatments in my case is something in its infancy so I honestly don't know when/if I can/will do anything in that regard.I do take solace in knowing that the sound and video I already get/have is top notch (IMO) and that improving the room environment would theoretically/supposedly only serve to make it even better. Perhaps some day.....

Charlie,

Just received the Master Handbook of Acoustics. Thanks for sharing! A lot to go through. Fascinating stuff!
