Recommend speakers for a large living room

I have a similarly large space.  35x30x18 high with mostly glass to the east, winding staircase to the north side with a balcony overhead, open to the southern direction to the kitchen and the west wall under the balcony overhead is all stone with a fireplace.  It's a very convoluted area to say the least.

I have a pair of Bryston Model T signature fully active speakers, however I am running them with the heavy duty PX1 external crossovers.  I have three subs spaced evenly around the perimeter to the sides and back, one is the Bryston Model T sub with three 8 inch drivers, the other two are made by Axiom Audio (who builds all of the Bryston speakers).  One is the EP800V4 and the EP500V4.   

If you are a full bodied type of listener, that is you enjoy powerful dynamic, super clean music; these speakers will impress you.  If you took it up a notch and added three amps each to both the left and right main speakers with the Bryston fully active crossover, it will take it to a whole new level.  I am not sure you can do all of this within your budget, but if you skip the 6 amps and just do what I am doing, you'll still be very pleased.

IF you want a coherent soundstage from most any location in that large area, you would have to go omni: OHM, mbl, and GP being the three I would consider with your budget. For larger mbl models, you still might have to go used on a $50K budget. OHMs would have teh unique advantage among those of going closer to walls for WAF in a lived-in space as opposed to a dedicated listening room where placement far from walls needed for true omnis is more practical..

If it were me I’d go biggest baddest OHMs and call it a day. Those would be the 5000 series currently with 12" main drivers. THere is even a limited availability 5015 version of those with built in powered subs that would do it all if available for just over $10K or so. My F5s are similar size, one model generation older, and no powered subs built in but I run them off 500w/ch BEl CAnto ref1000m amps. The Ohm Walsh model decision will be totally objective, mostly based on your room size. All models have similar design and sound, its just a matter of how much you need to deliver the bass best in any particular room.

Sounds like you are in NYC area so you might have the extra advantage of being able to visit the factory in Brooklyn for an audition. In any case, a generous guaranteed in home trial period is provided and if you are local, would not even have to worry about absorbing any shipping charges so there would be essentially no risk to audition in your actual room.

IF you are in Baltimore/DC metro area, I'd be happy to provide an audition.  Would just need some advance notice to plan.

In any case, Good Listening!

I would suggest listening to 30.7 Maggies, their size would not over power the room and properly set up the sound is amazing.

There are many fine choices, and synergy with the amp is critical as you listen to the candidates, Good Luck!

I heard these Hybrid Electrostatics at AXPONA and they were excellent. With curved panels, dispersion and imaging were magnificent.  As I recall, they were well under your maximum.  Low WAF if I had to guess but the sound may just override that resistance, if you face that problem. 

You owe it to yourself to at least audition Vandersteen 7 ii's.  After listening to them, you may find a way to come up with a way to defray the cost of the balance between your budget and the actual cost of the 7's.
