Hi! Great looking setup🙂.
Have you tried moving the sub horn to the align with the side wall? It should definitely smooth out the response even further (going from half-space to quarter-space when simulating in HornResp). Just a suggestion🙂.
Best regards

Finally, this monster is in my room and I'm extremely happy with result!
20-100hz range sounds amazing...just like I was dreaming!
Transparent, delicate and powerful!
Yes, I'm going to lay it down, so floor reflection make it half-space.
This idea is used in my mid-bass horn. It is half circle, but all measurements are exactly like it is full circle! So, I've saved one meter height! 🙂

Incredible U-turn in my jorney 🙂
I'm changing whole HF set (GOTO SG-3770BL + GOTO SG-188BL + RAAL) to single AER driver!
Angelo will be happy 🙂

Well...with my "no compression" concept I was fail to get proper HF from GOTO.
Construction doesn't allow to make very short horn without front chamber. If I have even small chamber, HF disappears from 6khz. If I make bigger horn, anyway HF disappears from 6khz. The only way works, when I put phase plug back. Than I have HF from 8khz, but not from desired 3khz. I understand, that I can redesign phase plug to get 3+kHz, but after I heard how this AER works, I've decided not to create too much problems for my self.
At the end, when I hear other systems I always thought, that HF are good from many conventional speakers. Horns are must for lower ranges, because they dramatically reduce excursion and increase efficiency of drivers, so we can hear LF as clean as HF. But for HF there is not such a problem. Excursion is always very very low, so timbre is always clear and transparent.
That is why I still have 5-ways system, but other 4 channels are below 1000hz 🙂
But are you happy with AER (or any similar driver) high frequency roll-off ? I can't live with that personally...

I am actually doing something similar with electrostatic panels instead of the horns. I don't have enough amps to listen to everything at the same time until I finish my Firstwatt F6. I have not substituted my hornloaded Yamaha Ja6681B and Raal 140-15D, only switched them off. But the result is that I have fullrange from 400Hz and I can hear everything a bit more clearly, without crossover points getting in the way. Before it was like I could hear things sometimes, but now I hear everything all the time. I do miss them. Horns are just so magical.
I disagree about using only horns for bass. I have not heard Pooh's giganto horn, but my own JBL 2220H (80-400Hz) in a horn did not do the job as good as a 2225H (65-400Hz) in a ported enclosure. The 2225H goes a little deeper and I sometimes don't notice that I forgot to switch on the subwoofer. It just sound more natural that the midbass channel can play some bass and also have midrange clarity. Maybe I should just build a larger horn for the JBL 2220H.

Don't compare AER with any other similar. There is no any roll-off.
I don't know how they did it, but I've never heard such a true violin. (WAV file was attached few posts ago).
And you know, I'm really picky regarding HF. I was using RAAL Lazy Ribbon 9" on top of GOTO HF drivers!
I think that the only similar HF I heard is from top Diamond Seas. Top diamond Accutons are a bit less resolving.
Yes, this is also the case. Getting the right phase with 3 HF channels is really trouble.
I think it depends... What makes my system outstanding is actually just one range 100-300hz where I'm using GOTO bass drivers in 100hz LeCleach half circle horn.
At 50-100hz I'm using giant 25hz 5m long horn with the same GOTO bass drivers.
And below 50hz - ported 21" sub PHC LFC-21sm
Yes and No . I heard a lot of beautiful full-range drivers also got a few in my home. Some of them sounds just great (Voxativ stuff for example) . But all of them starts to roll-off at 10-16Khz range , its just a physics because a cone size and weight , central HF tweezer helps just partially. Sure in some cases that's OK or even good for a specific taste . A lot of people are happy with that , but my problem is - I can still hear 15.5-16.5Khz on my both ears , so I am not happy with such situation... Also high frequency directivity becomes narrow in this case .
You heard a such great violin because of no bad xover connections between drivers at 1-20Khz , but not for a flat frequency response and no HF roll-off .
Sure that's just my 2 cents .

Instead of a Driver "Time-Aligned Horn System" ....
.... how about a Radiation Pattern Aligned System with DSP delay added to "Time-Align" the Acoustic Signals? This tack aligns the virtual images as well.

I can agree . Measurements and numbers are just for double checking in most cases with audio. At the most its just about feelings ...
But good pro measurements with good mics (at least M30 ) helps a lot to understand whats going on . And don't reject a phase measurements , they are important at same level with a frequency ones .

Umm, you threw that out with the phase plugs. I know of one compression driver that was actually designed without one that actually sounds good but it's main fault is bandwith. Removing the phase plug from a driver that was designed for one isn't a "mod" it is destroying the driver. Most people that have success with building horn systems shoot for a decade a driver because it works.
I meant phase alignment between drivers at common range.
Regarding phase plug, may be there is a way to redesign the one for GOTO.
GOTO's own competely covers diaphragm with very tiny holes around.
Sound with it is much less resolving...so, I've removed it.
