So they preach room treatments
Let me tell you it's true. I really knew that, I was impressed some years back at the improvement when I placed a tapestry on my wall to damp reflections. However, having both HT and stereo in same room brings on compromises. I have my 62" TV center of my speakers, back some but still not a good thing. My Dyn's I fired forward so this may not have been such big deal. My F52's fire toward the sitting position due to the wave guides on the tweeters, this is recommended. I was sitting and listening, it just came to me, I began thinking of how the reflections of the inside radiation would be reflecting right off that TV screen. There happened to be a quilted throw on the sofa my wife or girls use when we watch movies, I grabbed it and threw it over the screen, sat back down and, holy cow, what a difference. It was a large improvement, background was quieter, more detail, highs cleaned up, I was just amazed. I am just kicking myself as to why it took me so long to realize I should try something there. Any way I wanted to share the experience, the improvement was huge.
