Question: Sound Treatment behind the Listener?


I have treated the 1st and 2nd reflection points and I have sound panels between my speakers. I also have tube traps in all 4 corners, but I am not sure what (if any) should be done with the wall behind the listener.

That wall presently has a DIY rack system that holds about 5000-6000 cd’s. I believe it helps scatter the sound. But I’m not sure if that is the right approach.

So, what are you guys using on that wall? Diffusion, Absorbtion, Reflection? Anything else?

I would appreciate your thoughts.

@ozzy I'd be curious to hear what GIK says. That's a great service they provide - it was somewhat of an education to me in terms of the information they provided (and why). 

The best situation is to have no wall behind the listener. An open concept situation open to the rest of the house. The rear is then open between various rooms. This keeps reflections as late as possible and fractured as much as possible.

I have open book shelves on my back wall. They hold my technical books and years worth of audio magazines. Also a few diffuser/absorption panels and record cabinets.This has worked very well for me. I will add 2 bass tube traps soon. At the moment I prefer diffusion on my back wall. I’m 99% done with my room, not sure when I’ll get to the last 1%.

My head is 6 feet from back wall.

Maybe repositioning your CD’s in a random pattern might help? 6000 CD’s my goodness. Good for you.

Christian5s4,

How many of the GIK 6A Alpha diffusor/absorbers did you use?

I haven’t heard back from GIK yet, but Stillpoint’s says behind the listener treatment is not really necessary.

joenies,

BTW, the cd rack has many spots where there are few/none cd’s which creates alot of voids etc., in a random manner.

@ozzy Give GIK a few days. Their recommendation for my room was pretty accurate.
