SO my understanding is rear wall priority adding as many bass traps as possible. And its suggested that on the front a wall a 4 inch thick panel might help with boundary interference.
No recommendation on size and where?
Could a typical 2 by 2 panel (4 inch) directly behind the speaker provide results? I'm presuming larger the better but is behind the speaker the goal?
Regards

I'm sorry but I can't give you a definitive answer. The running joke is that bigger is better. Ethan has first hand knowledge of it In my case, I have my stereo monitors sort of "cupped" by my panels. I have a super chunk behind and then, effectively, a two 24x48x96" "ears" on either side of the speakers. One is for RFZ and the other is for modal/maybe sbir. You can try that out; no guarantees. Pics in my book. hexspa.com/listening-room-ebookThe only testing I've done involved moving a panel from one location to another. It was moved from behind me (on a corner) and to behind my centered mixcube. The measured response was worse. Whether this was because the panel was more effective in it's original location I cannot know for sure. That's why I'm being a bit unhelpful, because I don't actually have concrete facts to back me up. Thanks, -m

SBIR is why I suggest road band bass trapping rather than tuned absorbers. My recent article explains more about this: Bass Trap MythsEthan - I hope you meant "Broad Band", because I'll tell ya' - I was in a "Road Band" in the late '60's, and we didn't have much luck at all trapping Bass.

That's a beautiful kitty you've got there. Boy? Girl? Age? Name?

That's Noah. He had FIV (kitty AIDS) and died a few years ago from a stroke brought on by complications of the disease. But he still lives on in my avatar. Then we got Emma from the shelter, an older classy lady kitty, and Annie (RIP) who was even older. Emma is still with us (my favorite cat of all time), and more recently we got Bella and Lily as kittens, now ten months old. I know none of this has anything to do with SBIR. But if you care, all of my kitties from the past 20-odd years are shown in order on my Family web page: ethanwiner.com/family.html

He was a beautiful boy.
You're a good guy. I'm going to check-out that link.
That little sweetheart in my avatar is Sweet Pea, our ghetto-rescue girl, from one of the worst parts of Detroit I've ever seen - and I drove a taxi in Detroit as well as lived in the city through the '67 riots - so I know a bad part of town when I see one. Surprisingly, and counter to everyones' assumptions (including ours) this is the smartest, cleanest and most fastidious kitty we've ever had.
Thanks for the links.
Well then... we seem to have wandered off-topic.
Back to Boundary Interference!

Good on you Joe, I too always get shelter kitties, or kitties that need a home.

That's a great pinball vid. No vids here - just these two pics from Sweet Pea's first year. She had this total fascination with all things water when she first got here.

Adorable! Yes, some cats love water faucets.
