This might be a stretch, but worth a try! We just built a dedicated room for movie nights and have been happy with our CineMate Soundbar's performance for years, so we'd like to keep it. However, the room does echo quite a bit so I'd like to install acoustic padding to absorb sound.
Here's my question: given that the soundbar uses walls to throw sound around, are their guidelines about where to install/not install acoustic materials to maximize the performance of the soundbar?
I've never seen such as this from Bose. As far as I know, the only sound reflection you want/need it that of the left and right soundbar speakers bouncing off the walls back to your seating location. So, I'm thinking any sound deadening materials placed anywhere but there would help, especially carpet and furniture, etc.
You could probably find the location on the side walls where you don't want padding by finding where the angle of the sound is equal from the Bose and back to your location.
