Agree with you.I am a horn enthusiast as well.Both are stunning speakers indeed, but to me the theoretical advantage (I haven't heard either.) goes to the M9 even though I am a horn speaker disciple. That is because the Ultimate is not a horn system but instead a hybrid system that includes horns. When I first read the Absolute Sound review of the Ultimate I was shocked that this pursuit of SOTA only extended down to the bass where they crapped out with a single direct radiator woofer. Sheesh! This is like putting recapped tires on a 911 Turbo.
Horns for deep bass don't have to be house sized. Consider folded corner horns. Look at Living Voice's highly acclaimed horn woofers, etc. As I have said before horn bass is the icing on the cake.
Here is my diy system, it is a 5 way horn system with about 109db efficiency. It is a half a db better than +-3db, it is with passive crossover too so no dsp etc. The bass below 120hz is active open baffle servo, the rest is cf 110hz tractrix horn, cf 200hz tractrix horn, cf1400hz JMLC horn and fostex t500amkII tweeter.The question whether horns are better versus regular cone speakers is a often emerging topic .
I have asked very expirienced listeners on this site ( with potential golden ears, lol ) to provide some basic freq response data and prove their claim .
Iow to see if horns meet the minimal " gold standard " by staying within a +- 3 db limit over the 20 -20 khz range .
So far i have seen nothing .
Sounds impressive.any picture?Here is my diy system, it is a 5 way horn system with about 109db efficiency.

The graph shows f?at response. I also have the option to tilt bass, or adjust mid, upper mid and tweeter levels and match harman or toole target responses. Nowadays I am enjoying something between toole and harman, slight upper tilt at bass and slightly lowering towards treble. 200hz slight peak is from side reflections and will be tamed in my next room.
the sple response is in 5db scale and from 29hz to 22khz

Thanks I will check them out.I am a fan of very high sensitivity horn speakers.Photos on monoandstereo website from when this measurement was taken; https://www.monoandstereo.com/2019/11/okan-soylu-horn-system.html#more
There also should be a page on my system at this website (found it: https://whatsbestforum.com/threads/horn-based-system-from-southern-coast-of-turkey.26367/page-3) . You can see how the bass solution has changed over the years. I think I need to update that page too, as neither that one or the monoandstereo is how the room is the latest. Still it is 95% there on these pages and I will be moving in a few months...
I actually continue to develop my room and fine tune my speakers, This system is my private testbed and reference. I have been doing acoustic consulting and also started developing commercial speakers. They are not like these speakers but are unique new offerings.
Amazing work looks perfect...respectHere is my diy system, it is a 5 way horn system with about 109db efficiency.

Sorry but i m highly skeptical of your graph to say it gently , because its not possible to have a flat line in room response measurement in the 20 hz - 400 hz region with a passive X crossover .Here is my diy system, it is a 5 way horn system with about 109db efficiency.

I think, it would be better if I answer you on my system page as this is not the place for my system and its response. Please read there, as I will answer you on it.Sorry but i m highly skeptical of your graph to say it gently , because its not possible to have a flat line in room response measurement in the 20 hz - 400 hz region with a passive X crossover .
No manufacturer can achieve that not Magico not YG not Wilson not Dynaudio .......

Perhaps you or someone can explain; my understanding of accurate horn loading is that the mouth/throat size has to support the frqs it's playing and that it is determined by the low frq wavelength its reproducing. As such, a size of a horn generating 50Hz is huge. According to some online horn sizes calculations, something like 10X10X15 feet (We all saw pictures of these huge horn systems in Japan). So how are you achieving such a response with what looks like a 30" -40" horn, or the bass horn is not in the picture? I know there are "tricks" like quarter wavelength etc., but wouldn't that be like using a transmission line and not an actual horn loading?I think, it would be better if I answer you on my system page as this is not the place for my system and its response.

Thanks for replying, Bill. Since you seemed to be a “horn guy,” can you please explain the terminology. Many here refer to their system as a horn-loaded system (including you).
Does that also mean that only part of the system is horn-loaded? I mean, based on what I gather, none of these systems are fully horn-loaded, right?
I also have a pair of klipschorns in the Back of the room for occasional listen.great speakers.Yes, my biggest horn has about 40" diamter at mouth and about 40" depth. That is a fc 110hz horn midbass or upperbass horn. To load it down to its fc there is a trick called reactance annuling and that is what I am doing. Below 110hz my system has an Open baffle H frame servo bass solution. Even the big old western electric horns had open baffle solutions for bass
I have built 20hz horns but they were not front loaded, they were tapped horns. If you want to have horn loading below 100hz, there are other ways like folded horns or tapped horns that make them a little more practical. When I say practical, my 20hz horn was 8 feet long and the horn path was folded so the actual path length was about 16 feet. I also have a klipschorn which has a folded horn that uses the corners as the last segment walls of its horn. I guess that is the most practical (in terms of space) bass horn solution
