Yeah, while I love the aesthetic of the GIK Impression series diffusers. They were not as good sounding for the first reflection on the sidewall next to the speakers. I put the polystyrene grid diffuser back and the magic was back! much warmer and more balanced...That is likely all you need to change if you want to try something different. How my room is currently is the sixth picture on my page. Thanks for the tip on hanging the panels.
Beautiful room @gsal Congrats! I love the way the GIK panels look in your room. I just installed GIK in mine as well. I was wondering how you mounted the panels to the ceiling, did you use hardware GIK provided or stuff from the local store?
