I had a fixed screen for years and it drove me crazy for years. When playing vinyl or CD's through the 2 channel system the center image moves as the screen vibrates with the music. It does effect bass also but in my setup it was for the better, made it harder to locate the subs in the front of the room and the bass seemed to be better controlled. I think fixed vinyl screens act like a drum skin.
I finaly purchased a retractable and will never look back, all is good now. Do have to treat room more now for bass but that is easier to deal with.
