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

2 weeks after I got my horns and tubes, they have burned in for over 300 hrs.
I have been working on room placement with help of Brian Charney the designer , and art noxon and jordon Goulette of asc . We have traded pics , done articulation and frequency sweeps in room and analysed them .
also have ordered better tubes than stock tubes from andy , of vintage tubes .
my experience to date .
the tubes and horn combination is “dirty “ hopefully the newer tubes will better it .
there is not much deep powerful bass. The vocals are little peaked.
this is in comparison to my ayre , magico Jl audio system tweaked to the nth with room treatment etc . Eg. Listened to Steve Earle at 85 db thru my tubes sounded loud and I had to turn it down . Now listening at 95db thru my ayre, magico and it’s so clean ,  I want to play it even louder lol . 
newtoncr,
Excuse me if you have already answered this question, but did you listen to these speakers before you bought them? I'm wondering because full range back loaded speakers have a specific type of sound, and it seems from what you wrote in your last post that you were overall satisfied with your Magico setup.
What were you looking for when you made the change?
@roxy54 
no I hadn’t listened to these speakers before buying them .
I had listened to horn / low watt tube combo in multiple occasions. Always at dealers . Never in the optimal position in my house . I heard a presentation of vocals and instruments that was larger than I was used to . These listening sessions were brief . Other characters which I like like sound stage and depth and weight of music were not my focus during these listening sessions .
I wanted a second system with the larger than life vocals and instruments. I heard about the charneys his matching tubes and also talked to friends who I trust who have listened to the charneys . Due to Covid I couldn’t make the travel so I purchased the speakers and electronics. 
Trust me I think I have got exactly what I expected, the vocals are huge . One of my audiophile friends commented on the larger than life vocals . That was his flavor and he loved it . I am hoping with better tubes than the stock tubes I will be able to get cleaner sound . Tubes are noisy .  I don’t expect deep impactful bass with the horns . And I am not going to mess the tonal balance and unique flavor  by adding a sub . I hope to be very content with the charneys as my second system once I get the room treatment and tubes perfected . A great change in flavor to my main system  perfect after a long exhausting day at work when u want to relax with a pour of whiskey and listen Louis Armstrong and Ella play at around 75-80 db. They will be in the room with you through the charneys. 
That sounds good, and you apparently still kept your other system. Best of luck with the break-in and the fine tuning. 
TAD horn is designed for a TAD driver its phase plug improves loading for such why it exists the problem is folks using the TAD horn for non TAD drivers.
