Room treatments behind or between speakers?

Nothing between the speakers? I don't think so. It should not be your components, including a TV. Some years ago I added a free standing Furtech Room Diffuser to fill the void. Does wonders. Plenty of stuff on the net about that product. Behind the speakers? Depends, its complicated. With out knowing how your speakers are 'ported', if at all, can't provide advice.

Samhar...yes I am still behind the Orange Curtain in south OC.

I'm still in the process of deciding which room will be "The" listening space. I'm not currently using many of the treatments from my last house and was wondering if you'd be interested in using them for the purpose of evaluating your space/needs. I'm not offering this to sell them only as a short term loan and the Phonics Real Time Analyzer and test CDs, if I can find them !!!!! I'm in Torrance three one zero four nine zero zero eight eight eight. Using the RTA you can install, move or remove traps and view the results. If you go to my system and open the Real Traps and ACS Tube Traps every thing I have is listed. I'm currently using the ASC 16" in my front room. I've been recovering from a surgery and haven't been able sit and "tune" my system.

Bucanero....instead of thinking, remove anything between your speakers except the amp on the floor, and hear the speakers open up with added clarity. I never heard a system that sounds better with something between the 2 speakers.

Samhar, thank you for the generous offer. Let me check my schedule to see when i have some free time. Thank you again!
