As the topic was what causes glare, I attempted to describe a method of reducing or eliminating glare caused by acoustics in the listening space. A 2'x4' panel will accomplish the same result but too much absorption will shrink the sound-stage and reduce the live music experience. There is always a compromise to be made in most rooms. Few homes have rooms designed with audio reproduction in mind unless the architect was working in conjunction with a sound engineer. Most rooms are merely boxes with square corners, flat and smooth surfaces which leads to excessive reflections, standing waves and nodes which all wreak havoc on recorded music playback.
The method I described will reduce what i refer to as hot spots or reflection points which hit the listener while seated in the sweet spot. There will still be reflected waves but they will be ambient room reflections that shouldn't compromise the listening experience unless SPLs in the room are excessive. Excessive SPLs are another topic for another time.
This method will cost you less than $20.00 unless you have to purchase a step ladder.
It could very well be time well spent.
Cheers,
Jon
