Seeking horn array loudspeakers with a maximum price of $17,500.00 per pair.

Volti Lucera owner here, formerly a Klipsch Heritage guy. I love my Luceras, and no way are they grainy, or lacking in the low end. It was a pleasure dealing wth Greg Roberts at Volti. I got to select the veneer (Paduak), and he got them done and shipped to my door in about 2 months. They are gorgeous and floor me every time I experience them. Highly recommended!

Greg is a heck of a guy. Obviously puts his all into his product. Additionally he’s great at answering questions, making sure you the consumer are fully satisfied. I never felt any pressure from him and I spent a full day with he and his wife. The experience was more like finding a kindred spirit and hanging out with an easy friend while being immersed in some sweet HiFi. 
highly recommend potential customers see if meeting Greg at his shop is possible. It was an experience I’ll not soon forget.

Op want array horn speakers?

@kckrs FYI, the Klipsch Jubilee system operates as a vented box below 100Hz. 

''PATENTED HORN-LOADED VENTED SYSTEM The patented low frequency enclosure of the Klipsch Jubilee is designed to provide magnificent presence, by leveraging the efficiencies of both horn-loaded and vented systems. The typical vented system already increases the efficiency and sensitivity for extended low frequency performance. Horn-loading this system allows the Klipsch Jubilee to be a staggering 10 to 20 times more efficient than a conventional loudspeaker. This results in unrivaled low frequency performance, maximizing output while minimizing distortion, for dynamic and clean bass.'' See here

You are looking for something that sounds good at most volume levels.  That is one of the major strengths of horn systems.  But, it is also the strength of other types of speakers like the backloaded horn full range driver system like those from Charney Audio.  I like their Companion models.  I heard, and liked this model with a Voxativ and an AER driver (I liked the AER a little more).

AsI mentioned above, find a high efficiency speaker, horn or otherwise, that you like, and then consider getting a low-powered tube amp.  The amp is also very important to great sound at low listening levels.  Most solid state amps need to be played at a higher volume levels to sound lively.
