That is a very insightful observation!You will just buy everything with "tube" in its name Ron !
Unfortunately this thing apparently does not actually take a tube!

No. The AVAAs are great. I still would like a fourth one.
These new TubeTraps will replace the standard TubeTraps presently in the front corners of the room.
Yes, but isn't this countered by softening of the brain?
If only it was just the brain that went soft.
I just realized a question:
I have two room modes, one at 45Hz and one at 60Hz.
One pair of Helmholtz resonator TubeTraps is tuned for 45Hz and the other pair is tuned for 60Hz.
Part of the ceiling is 9 feet high, and the other part of the ceiling is 14.5 feet high. One part of the ceiling is causing the 45Hz room mode and the other part of the ceiling is causing the 60Hz room mode.
How do I figure out in which corner of the front wall does each pair of tuned resonators get located?
Can I assume that the 9 foot ceiling is generating the 60Hz bump, and that the 14.5' ceiling is generating the 45Hz bump?

These modes are more likely the length and width of the room related. You will get other complex modes taking the height dimensions. The length and width usually cause the lowest frequency modes as these are the longest dimensions
Thank you.
The length and the width are the same on both sides of the room. The only asymmetry is the ceiling height.
find a nice double bass or cello recording with lots of growl and play around with it. something that got too thick as you pushed it before. especially the transition from behaving to breaking up. see if you can improve that musically. find something digital to allow for speedy A/B's.
or measure.
or do both and compare results.
Your room is a square? That is geometrically the worst shape for a listening room.

No, it is a rectangle. The front wall and the rear wall are the same width; the left sidewall and the right sidewall are the same length.
Ok, not what I was talking about. The long wall is likely responsible for the 45 Hz mode and the short wall the 62hz. These are standing waves based on your room length and width. There will be other modes related to ceiling height but it gets complex quickly.
So does this mean it does not matter in which corner I put which pair of tuned TubeTraps?
The new ones are definitely staying in the corners. The question is whether I want to play with diffusion side out positioned old, conventional TubeTraps behind each panel and in the center of the front wall, or just sell them.
Hmmm...interested to see what you find!
The standing waves created by the length and width dimensions likely coexist together rather than in a separate place. It is complex though and placement may make a difference. It seems to me that there is also research somewhere that says while the most dominate standing waves are said to be found in the corners that may not always be the case.
Ron, have you considered putting one of each type into each corner, i.e., the 60 Hz tuned TubeTrap on top of the 45 Hz tuned trap, or the other way around? What does Art Noxon at ASC say?
As for the old traps, have you tried putting them in the back corners of the room? (Honestly, I forgot what your room looks like in the back, if it even has such corners or if it's more of an open layout.)
No doubt the vinyl's piano "banging" is accented. The tone richer throughout especially the mid-lower range. Her voice is very thin in both recordings however. I'd say I enjoy the piano much better on vinyl. Thank you for sharing.
No, I did not think of this, thank you! This is an interesting idea, if there is no discernible area of greatest pressure for each of the room mode frequencies.
I did not ask him about this, but I should.
There is really no room in the back corners.
