Love this topic as it’s not as common but extremely important. Working with the folks at GIK (or other acoustic expert) is key. REW has been a very helpful tool along with my ears, and the USB mic was a worthwhile investment as I’ve used it multiple times over my three year journey in treating my room. I cannot recommend it enough. And the GIK folks will use those REW measurements to help diagnose your room and suggest treatments. My listening chair is only 2’ off the back wall so pure diffusion wasn’t recommended. I’ve read elsewhere that pure diffusion on the back wall isn’t beneficial unless your listening chair is 6’ or more away from it. GIK instead suggested their combination diffusion/absorption Alpha series panels, as I had low frequencies that needed to be tamed along with me trying to make my room sound bigger, My last and final addition was adding 3 x Q7D diffusers to the front wall and a pair of wall hung monster bass traps directly behind the speakers. My small square room has never sounded better.
Absorption, Diffusion or a combination of it all?
Looking to add more acoustic treatment on the wall behind the speakers. Currently using GIK absorption panels (242).
Planning to add two more panels that would hang pretty much directly behind the speakers on the upper part of the wall (higher quality image on my system page).
Any benefit going with diffusors?
Thanks!!!
