I'm quite interested in the results of the room sweeps/REW analysis. Are you still planning to post them as time allows?
Unfortunately unless we have access to the raw files and analyze them on REW the information is extremely superficial.
I consider that analyzing decays and waterfalls from different perspectives is a minimum. But I would surely appreciate seeing and debating them.
In a sense, I think you are correct inasmuch as what measurement information is presented in terms of value. Yet in any properly performed measurement and minimum/sufficient supplemental information, very much can be learned - and it would be very interesting (though, myself, I'm not big on debating). But, yeah, I'd be excited to see them.
yes, but both jim smith and micheal burns have told me to get at least a few hundred hours on the system before measuring
Hugh, and fellow audiophiles,
Who's planning to attend AXPONA 2022 in Chicago next month?

Fun time lapse video of Kodo install. I brushed off an old Hero4, actually worked.
We just posted three videos we shot of interviews with the install team on our Facebook page. That should provide more details on the project.

Interesting that Jim Smith set up the speakers in the middle of the room. Actually that is very telling. When you let your brain take care of the room correction by listening near-field it takes the room out of the equation. How about seeing the measurements and pictures or diagrams of the microphone placement and source set-up. Was a calibrated source used for the measurements? Or were the Gryphon speakers used as the acoustic exciter?
had Mike Burns from WolfSong Audio come by today to further measure the room.
to recap: the room is 12’ 2” high, 21’ wide and 31’ long. QRD diffusers are 16” deep.
setup guru Jim Smith finalized the speaker position. The speakers are now almost mid room. Jim was very pleased with the outcome.
software used:
Calibrated OmniMic V2 running the OmniMic RTA software. Mic was equidistant from the AMT tweeters at 13’ 7.5 “ Mic was 42” off the floor.
The graphs are labeled as to what was measured. All measurements were done at a more realistic 85db reference. 1/6 octave smoothing was used. Mikes summary is below the attachments. I dont pretend to know how to interpret all of these which is why i asked Mike to summarize for me.
Folks This is it for measurements. Not going to run anymore. I am sure this will not satisfy everyone
and i am sure the comments will be entertaining!
Mikes Summary:
Overall the Bass region runs very evenly with no more than 5 db variation from reference and the room does not hold on the reverberant notes in the 200 Hz and below region.
Listening notes: Bass is explosive and nuanced. Timber and tonal cues in the tambor are spot on. The weight is tremendous while having no negative effect on the overall soundstage during deep and loud passages. Kick drums are particularly fun with “kick you in the chest” impact.
Image size is slightly larger than life in a good way. Since the Barn is a quite large space, the image size fits with the scale of the room and the speakers. Multiple singers on stage are easily differentiated in space and tone. The system scales wonderfully from single instrument to full on live rock recordings.
