This is a great real world case study Jim, thank you for sharing. I have a very unconventional room layout that I'm also embarking on a journey to acoustically treat. I'm going to try and document here as you did as this is super helpful.

Regarding your first reflection point panels, did you try the 244s with scatter plates in this position? Diffusion is still the biggest mystery to me, when to use and when not.

No, robdb2, as indicated earlier in the thread, I'd tried the scatter-plated 244s at only the second reflection points. And thought full-range 244s in that position elicited "better" performance from the system.

However, I conducted that audition before finishing up the acoustic treatment with the DIY panels covering the jewel cases...and making a number of component changes (replacing the active preamp with a passive, upgrading the adapter connecting the Uptone Audio REGEN to my USB DAC, replacing the standard USB 3.0 cable connecting the music-source external drive to the laptop with a Wireworld Starlight, slipping Stillpoints UltraMinis under the laptop, DAC, and amp, and--as of this coming Tuesday--replacing my old Tara speaker cable with Blue Jeans/Belden 10-gauge).

Once the new speaker cable settles in, I'll give the scatter-plated 244s a go at the first reflection points and maybe again at the second reflection points to see what, if any, changes I hear. I don't know the precise auditioning timeline, as I'm now neck-deep in a murder mystery I started writing in July and am spending most of my time these days working on that.

If I hear any changes that I consider improvements with a repositioning of the scatter-plates at either reflection point, I'll post here.

Jim
