He is more than welcome to come here to make his case. As I told him there, if they weren't posting about us, I wouldn't respond.

Erin reviews GR-Research NX-Bravo

Yes, but surely you understand how Danny is? He sees any negative as "Excess criticism" and makes excuses.
My post about Erin being a bit too "polite" on this speaker was based on seeing other reviews where he "Called out" distortion that was lesser as a negative, but on this speaker he seems possibly "Less" concerned by it.
I agree Erin was fairly neutral and the measurements speak for themselves, but at the same time, his assessment of the measurements factor in also.
I feel he a "bit" downplayed the high distortion and the high price. But otherwise quite decent and fair.
While agree to trying to hold Danny accountable, AudioCircle supports his censoring of content. The corresponding AC thread has been quarantined and now only members can view. It is part of how Danny controls any content he considers to be negative and where he cannot control the narrative.
O/k, didn't knew that was possible. I do not want to infringe intellectual property rights, hence won't copy the actual graphs from Erin's site. But look into the distortion a bit further.
Close to 10% at only 86dB@1m in HD, up to 1% in higher order HD in upper mids / lower treble. I personally deem such to be inacceptable right away. The intermodulation - that's the distortion that generates subharmonic artefacts, hence is not masked by the tones played, rises up to 15% (!!).
This all is an indication of something going out of control entirely. Something to be designed to act linear gets chaotic. You cannot expect to remotely predict what actually is happening. And so, falling back into a subjectivist's attitude for good reason, I would not see such a device as the right tool to convert my recordings to sound. This is all way beyond of what we have experience, and learned to live with.
I have some experience with true ribbons, AMT and magnetostats (the planar design used here). Most of them showed more or less chaotic behavior. Sometimes it is intended see DML speaker, sometimes it leads to the planar to destroy itself. The original maker, BG, was praised to solve the problem to a far extent. But the Bravo is, frankly spoken and taken by the data, a little bit crass.
A final question, what does the Swiss cheese in the title picture mean?
Would have to ask Erin to be sure, but Danny is known for saying other speaker crossover parts are cheesy.
Danny being one of the admins on that forum, I don't think there's anything surprising about the censoring of content.
ASR supports censoring of content as well. Neither are free speech platforms and both have obvious narratives.
Not sure what you mean. Do you have experience as a member of AudioCircle?
There is a vast difference between what is tolerated on this forum versus there.
Two different forums, two different business models, two different narratives.
Dissimilar in almost every aspect. Except in the aspect that rule violation will get you in trouble.
Danny didn't break any rules on this forum. Amir did break the rules on that forum.
What rule? This is their TOS: https://www.audiocircle.com/index.php?action=agreement

The GR Davidians are quite like a cult.

Well. That's just plain amusing.
Yeah, it is completely unacceptable. I fully expect this speaker to have the usual raspy sandpapery treble I expect from planar speakers.
Even in kit form, I'd say the Swan DIY 3 way (even un-modded) is a significantly better value than these. IMHO.

Hivi 3.1A DIY Speaker With Sehlin Mod Review
This is a review and detailed measurements of the Swan Hivi 3.1A DIY Speaker kit with modified crossover by Sehlin Sound Solutions. It was kindly sent to me by @Mudjock as tested. The kit by itself goes for US $300 including Prime shipping. Unusual for a speaker kit, it comes with everything...

I think some comments may be Danny himself or employees of his. They have done similar things before, so most likely the sameThe GR Davidians are quite like a cult.

Danny, for sure, was the first one who suggested it may be the best speaker Erin has ever measured. There were only about 7-10 comments at the time and I didn't go back until it was "quarantined".

I saw quite a few measurement charts for his NX-Bravo on his website ...
Is that a new marketing approach, show-off overly smoothed charts, cutoff at 200Hz, and they don't look that great...
Maybe there should be a shootout between NX-Bravo vs. Ascilab C6B ...

Whereas the smoothing and limited bandwidth can make Danny's measurements appear better, he is using a zoomed SPL scale and that will make them appear worse than most more standard (50 dB) scaled graphs.

I would guess that the 200Hz cutoff is due to his Clio system. With normal quasi-anechoic measurements you can get down to 350-200Hz but then need to merge the farfield and nearfield measurements. He is probably just skipping the nearfield step. For a two way, probably not a big deal as box modeling is accurate. For a 3-way crossed at 300-350Hz I'd want to see the low and response, but I didn't see any 3-ways on his site (although I didn't look very hard either).
This is his center speaker I tested that is MTM:
Clearly you want to see low frequency response to catch mistakes like this.
