"Exactly where you want it"is not a bad outcome !Hi Phi!
I don't think reverberation time was a problem. Jason found the room overall subjectively to be on the "slightly live" side, but that's exactly where I wanted to end up.
A certain electric keyboard key in Sarah McLachlan's "Witness" lit up the room boom like a Maglite. I have to check to see how that song that sounds now.
Most importantly how is Lola
Did Jason comment on speaker positioning? I suspected issues with that dropped soffit
I forgot to mention that achieving this bass boom improvement required moving the listening chair forward four or five inches. I have to see if this has screwed up the clear center imaging of a solo vocalist.
Peter, pink noise is not flat .. it drops 30db from 20 hz to 20khz so that plot actually shows a quite flat response which is a very good result.I suspect listening seat location has a great deal to do with the improvement. Now the question is: how much is the result of the stuff he brought into the room and how much is simply a new seat location.
I appreciate the asymmetry of the upper half of the room and having to deal with that imbalance. I am glad you are noticing an improvement. It seems as though you’re high frequencies start falling off a little bit later also. Did you happen to show him the frequency plot and ask him if he thought that corresponds to what you are hearing from the listening seat? It seems to me that the 40 DB or so drop from 50 Hz to 15 K is a lot.

Peter, I guess they suggest a emphasis in high fr ( or rolled off bass) but I am not sure how accurate the ipad is .. or if folks have a consistent method of measuring ... as I write this I wonder if pink noise is 100 percent consistent in its slope accross the various sources !Thank you Phil for explaining that. So what are plots that indicate only a 10 or 20 dB drop from 20 to 20K telling us that is different from what Ron’s plot shows?
It would be helpful if Ron optimizes the back wave from his panels on this front. He has been hesitant to do so due to weight, but sliders with Dons help will solve that issue.I suspect listening seat location has a great deal to do with the improvement.

This is sounding better than I remember previous videos having. Will be interesting to hear how further changes are shaped by introduction of a different TT.

With Dipoles, I would definitely AVOID absorption behind the speakers and OPT FOR diffusion.This is true.
But I like the depth I am getting with the speakers about 8 feet in front of the front wall.
Even though I have never before absorbed or diffused the back wave of any planar dipole speaker I have ever had, I ordered four 96" x 30" x 1" thick absorption panels to experiment with different levels of absorption of the back wave.
