At @paul172 house, the system sounds terrible without one Black Box. Itās not really terrible until you hear it with the Black Box. His room is the most convincing I have encountered. Weird.
Coffee.

Very promising, my box should be here tomorrow and I hope one could be enough, if I understand well the best positioning is centered between the speakers, on the same line or slightly forward it. If it works (Iām not a big fan of SR products) I could consider also the HFT standard, X and Wide Angleā¦ only if Al will approve them.
The Box is Black, of course, like coffee.

Start there, but be adventurous. Move it around. You never know what youāll encounter. I was most amused at how much I like two in my SUV.

The box is made in white also to coordinate with decor or speaker color. I didnāt want the black box but once I heard in my system I couldnāt unhear it once it was gone.

Did you ever tried the PSI AVAA C214?
I hear good reviews about them.

Never heard about it, thanks for suggestion. Let me see (hear) how the Black Box works before, I like the idea of a passive resonator but who know?
If the black box works in Lucaās room, then it may push me over on a white box. I donāt think I can hide either one from my wife though. That could be a problem.

It should work on ceiling as well as floor. She might not notice it as soon up there. Seeing it will not be underfoot. That be a bit better than mounted to a Roomba Robot.

The last bit of clarity I have left leads me to make a proposal: letās detach ourselves from this forum for two weeks, in an attempt to try some sort of rehabilitation!
At least until the new year!

I believe it. Itās good you do not take hallucinogenic mushrooms for tweaking idea generation . Thereās no telling what you might try next.

PSI AVAA seems best in high end class, as long as getting bass and bass room nodes to work are discussed.
SR blackbox are probably the second best product out there.
Where SR BlackBox only works on one node with 2nd and 3rd harmonics (like 40hz, 80hz and 120hz?) and not the minor or huge other nodes that also might be present, PSI AVAA seems to do a better job with more performance and working over a larger span of frequencies (15-150hz) simultaneously.
Most important is likely that PSI AVAA is likely better at separating room bass frequency problems from what is correct true direct āfrom speaker bassā (the kind of bass you what to keep to 100 percent).
AVAA are supposed to leave direct true from speaker bass unaffected while doing a great job at eliminating room problems.
I have not listened to any of them (SR blackbox or AVAA) but have experimented a bit with 50hz and upwards absorbers behind speakers and with Accustica Applicata DAAD (used to be considered best in class regarding high end treatment where time changed diffusion and absorption could be had at the same time - Today most Tubetraps and other products have copied Accustica Applicata ideas and they are not so much known any more).
Note
PSI AVAA 20 is more known in the studio market and not so known in the high end audio market. There are many tests of performance on YouTube, but most of them in studio environments.
Note 2
PSI AVAA 20 is passive. They recently launched a second model, an active one.
One of the few high end audio reviews of the second active model can be found at Alpha Audio website. They also have got a YouTube review and gave it āTop 5 of 2023ā award.
Alpha Audios reference listening room also have got Accustica Applicata DAADs at the front wall corners (2 on top of each other) making the room sound much larger and deeper.
Getting the bass perfect and getting the room to become the perfect listening environment and then top that with getting harshness and glare down can make midfi sound better than ultra high end.
Thatās indirectly what this grounding thread is all aboutā¦

PSI description alone will make this a must try for Al and Lucaš
I donāt see a white one on this, and I donāt know if it works at the back corners since itās the only possible location in my situation.
Edit: seriously this thing attracts me more than the white box, and the theory is sound. The only problem is that I have too many serious upgrades in consideration alreadyš
