Horn speakers , high efficiency but not “shouty”


I am interested in a high efficiency horn with SET AMPS, in a 12 ft by 18 ft room. 9 ft ceiling .
I have narrowed my choices down to Charney audio Excalibur http://charneyaudio.com/the-companion-excalibur.html
and rethm maarga v2

would appreciate input from any one who has heard the above speakers or someone who has a similar system . 
listening choices are vocal music , no classical music.
Very rarely might want my system to play loud party music .(extremely rare ) does not have to play it like solid state system. Thanks in advance

Apparently not the tippy top yet, or something to that effect :)


well if we specifically define non shouty horns as ’tippy top’ then i suppose you are correct

over the years i have heard avantgarde duos/trios, sadurnis, klipschorns and cornwalls, tune audio animas, cessaros ... maybe none designed properly or were set up correctly

i have not heard western electric theater horns in a domesticated environment though...



@jjss49 I've found that you have to be careful with the amp that you use on a horn. It must have a clean first watt! If it has distortion issues like higher ordered harmonic generation (a problem with many solid state amps) you can certainly wind up with shouty (although it really won't matter the speaker). A good horn is a very revealing device and you do have to have your ducks in a row to get the best out of them. But OTOH that can be quite rewarding.


And to be clear some horns do have problems! For example the TAD machined wood horns have an artifact caused by an error in the throat design- its got an unpleasant peak at the bottom of its response. But with a bit of careful computer simulation I know of a modified version of that horn (Classic Audio Loudspeakers) that does not have that artifact and so is very smooth and relaxed, yet very fast and detailed. When you have those qualities together that's when you are making progress as they point to low distortion.
Speakerlab 7's - 12", 10", 15" horn and 7" horn. Both horns are plastic. No "bite"! SQ beats any Heresy and Cornwall. Bass goes down below 40 hz. I bought mine from Habitat for $100 + $50 delivery. I can live with the flat black white speckle finish!
One of my relatives is an experienced audiophile in the Midwest and he has one of the massive Klipsch horn speakers.  The sound is super impressive and alive sounding.  He uses very expensive Japanese mono tube amps.  I think Shindo or Wavac.  Like fifteen or twenty grand a set.  It is really a wave of sound coming at you head to toe.  To me it is very exciting but maybe a little exhausting if it is a long listen.
