Recommend speakers for a large living room

Sam Laufer's new line array speaker (The Note) is a good candidate. It is not an OB design. It does require subs. I believe he is still in Brooklyn so not far from you. 

There is lots of tasteful room treatment available. I would strongly recommend consulting with a professional in this area. The room doesn't have to look like a sound studio to be treated. 

We design and manufacture dipole line source speaker systems and know about room integration challenges. A true line source is worth considering. Call Sam and ask about The Note. I have no affiliation with Sam or his company.

Several here have suggested MBL, I concur.  I will add, propper amplification IS required.  I power mine with an ML 33H amp.  someone else has suggested Dunlavy.  I have these as well and highly recommend them.  

MBL can be enjoyed by many as the listening/seating position isn't as critical do to their design.

Best,

My vote is Meridian DSP 8000, a subwoofer will not be necessary and you will not find a smoother effortless exact sound especially at lower pleasant volume. They can easily fill the rom in stereo and many Meridian owners are hooked on Trifield as well. Since they are digital the lengths of wire is nothing in comparison. You can pick up preowned pair for $16K and upgrade to SE later. I believe there is also a single on this site. If you look on the Meridian Hitchhiker site a lot more information on preowned equipment. I will say that I have been enjoying and building my Meridian system for over twenty years. I had Magnapan and Martin Logan prior, and got tired of the amp, preamp and wire games.

I’ll second the comment by Atmasphere above, to the effect that special consideration should be given to speakers that are easy to drive.

That would be beneficial in several ways: Whatever amplifier(s) you choose will most likely sound better; the need for less power is likely to lower the cost of suitable amplification considerably; a greater percentage of whatever amount of money you choose to invest in amplification would be likely to go toward quality rather than toward watts; and, finally, less heat is likely to be put into the room by the amplifier(s), if that may be a consideration for your apartment.

One speaker which certainly meets that requirement, and that would be suitable for use in a large space such as yours, and that I believe is consistent with your budget, is the Daedalus Zeus that was suggested earlier in the thread.

Although with those as well as many of the other speakers that have been suggested the need for multiple listening positions would seem to be problematical. If you want to consider Daedalus a conversation with Lou Hinkley (its designer/manufacturer), who is wonderful to deal with, is likely to provide you with helpful guidance about suitability and placement.

Good luck. Regards,
