Question: Sound Treatment behind the Listener?

Thank you that is very good advice.

You are right on. I like the sound I have but am concerned that when I remove the Cd's/rack the sound may change.

What about Stillpoints Aperture ll's. I already have 6 in the room, would a couple more of them behind me work well?

I believe if you place one Stillpoint Aperture II on each side of a 6" thick absorption panel that is set directly behind your listening seat on the back wall you will be set perfectly and won't notice the CD racks as being missing. Mount them so the centers are in line with your ears. The sound probably will be even better. This assumes you have those bass traps in the corners of the back wall.

You think I will still need the 6" absorption panels even if I use the Stillpoints Aperture’s?

Here is what Stillpoints Aperture Panels claim:

"The Stillpoints Aperture is the only acoustical product that will give you both absorption and diffusion at the first reflection points of a system. And you want both!"

• The Aperture’s unique trapping system captures an area of waveform much broader than its small surface area would suggest.
• The Aperture can be used to trap waveforms either facing the wall or, facing away from the wall.
• The Aperture effectively increases soundstage width and depth. This is especially true for smaller rooms. (See the Michael Fremer review in Stereophile, Feb 2016.)
• The Aperture will increase the dimensional perspective of the image structure.
• The Aperture focuses music and voice without room boundary.
