Horn speakers , high efficiency but not “shouty”

I have enjoyed Classic Audio Loudspeakers T-3.3 field coil horn speakers for better than 4 years now and they mate quite well with my Atma-sphere Novacron  amps. OTL's seem to have a special dynamic with these speakers. They are very special. I previously could not stand a horn speaker

A lot of the horn and other high efficiency systems I like that manage to tame excessive midrange peaks and nasal colorations are quite expensive (e.g., Goto horn systems, G.I.P. Laboratory drivers, Feastrix drivers).  The Charney, Volti and the Klipsch heritage systems are the exception (particularly something like the Klipsch Cornwall IV).  The Classic Audio field coil speakers are also not excessively colored or peaky, but, for my taste, they are a little too bright and a little to hard and brittle sounding (I still think they are certainly worth a serious audition).

While I thought the Charney speakers I heard played loudly enough, I did not hear them pushed really hard.  I would not expect a single 8" driver to be really capable of extremely high volume levels, but, on the plus side, I like horns and high efficiency systems because they sound very dynamic and lively without having to play at high volume levels.

Not sure how sensitive you need but the JBL 4367 at 94db is not shouty at all to my ear. Just move from the Heresy IV which was also very easy to live with but the JBL takes it to another level. Maybe too revealing at times but I’ll take an honest speaker I can tune with amps and sources.

hORNS by Autotek out of Poland are outstanding as well, and not shouty in the least.  I have the Symphony model @ 95db efficiency- have run it with 211 SET/Aries-Cerat Incito S preamp; and Grandinote Shinai 37-watt pure class A solid state integrated with equal success.  The Beryllium compression horn driver is super smooth yet revealing, and as mentioned above, plays so well with a variety of good amplification- HIGHLY recommend you put this brand on your radar screen.

I have also been to Charney Audio in NJ a few years ago- the big Concerto speakers were quite good, however given the ultra-revealing nature, SET was mandatory to get the best out of it.  Brian had an amazing custom Audio Note type 300B setup; preamp; and dac- and he built everything.  His woodworking and metal shop in the basement are incredible as well- he is a true artisan and super nice guy as well.  He even built the battery power supply and modded my excellent 47 labs Flatfish cd transport.

From my personal experience I can only confirm that Lowthers are shouty.
Nevertheless, SET amp tames that down to acceptable levels. I used 15 Ohm Lowther DX2 in home-made Fidelio enclosures for quite some time before I wanted a change, and I still hesitate to let them go as they were very good at some things. Shouty, yes, even with 300B SET. They were basically useless with solid state, that includes Pass Aleph 4. My room is bigger (around 20’ by 23’ with large openings), with solid state amps there was no bass.
