Like many (or most) people, I am using a small non-dedicated living room [11.4 W x 8.0 H 18.4 L] which doubles for home theater and two channel stereo. All too common. My floorstanding speakers are 3’ off the wall. For optimal two channel sound, it is not ideal to have anything between the speakers. I have a TV there.
Despite the TV, I get a fairly good image which seems to come from the top quarter of the TV. Both my speakers and my stereo REL subwoofers disappear. As I don’t want to destroy my decor, I have several GIK Acoustics 4" thick movable freestanding acoustic panels on order. They will arrive sometime before the end of days . I have experimented with diffusing the TV with a thick blanket during critical listening.
Would placing an acoustic panel behind the TV on the front wall, while simultaneously having a panel in front of the TV improve the sound/image?
Just as an FYI, if money were no object, Acoustic Fields solved this pretty well. But this solution is a down payment on a house!
