Recommend speakers for a large living room

I also vote jbl everest . 
My room is 56x36x15 . I dont use anything but jbl . Currently my set up is wide dispersion tweeters and horns 2405 and 2441 w 2310 lenses . 2235 15” woofers and two 2245 18” subs. Horns and tweets powered by 100w rogue tube amp , woofs powered by 150w mcintosh , and subs powered by 600w x 2 mcintosh . 
More than enough oomph to fill the room . With the ability for sweet dinner time listening and intricate detail even at the lowest volumes . And all out mayhem at the higher registers.

 This entire system is half the cost of the budget you claim to have for speakers . By the time you have worthy amps and preamp youll be at 100k. Difference is i have a setup i can tweek infinitely .
 A 100k setup is what it is . You will have to like it even if it bothers you like a drip on the forehead. Chances are though a mcintosh c52 pre with a couple mcintosh mc1.25k amps and a pair of jbl dd67000 everest will sound pretty freakin awesome. And look drop dead gorgeous to boot . 

If it helps with your planning, bear in mind that speaker setup (positioning) has as much influence on the sound as all of the hardware, if not more.

At the very least make sure the speaker manufacturer will visit your room and place the speakers to work optimally with your room. 

I design and install loudspeakers for Aluminous Audio so I can speak to the critical nature of speaker placement.

Alta Audio's HESTIA-sensational 32K-35K /pr.I was part of a review panel and was really taken with these. Out performed everything we heard including MAGICO, WILSON, FOCAL, JOSEPH AUDIO, YG ACOUSTIC, KEF and RAIDHO to name a few.

Thanks all. Adding Magico M6's & Alta Audio Hesta's to my listening array.

@glupson the apartment is a loft in Soho, Manhattan. With that said, if anyone recommends I speak with someone in the area that can help with the project that would be helpful.

On room treatment plans, I plan to use some bass traps in the ceiling corners, but I am also open to doing more but I do want to make sure the aesthetics are preserved - its a living room at the end, not a dedicated studio.

Great open baffle Great new Speaker 
from Spatial Audio X3 with powered low 
Bass Xover from 90 hz on down, world class AMT on top German BMG midrange mid Bass, and emmenande pro series bass driver with latest 
200 watt Ncore Bass amp. It nice wood finishes. Being too over 95 dB efficient 
you can use a Smaller tube or solid state amp with great results ,and a 60 day satisfaction return policy .

a no brainer they beat speakers 3 x their cost .Not investigating these would be a Big mistake only out 3 months but raves at the shows ,check out too on Utube.
