Speakers for a small room

My room is 11' x '16 x '10. I spent 2 years learning room acoustics and treating my room. I spent another 2 years going through speakers that were too big for my room (e.g., Golden Ear T2). A year and a half ago I got a pair of Kef Ls50s. Last week I finished dialing them in. They are incredible. I'm very happy with what I'm hearing now. 

Ultrek BINGO! 

This is exactly the coaching we expouse. If the total volume of the room is small, then you need monitors that will not over load the room with bass. 

Ideally you would not want a speaker with bass that is lower than mid 30 hz bass response. 

So a great pair of monitors is what you want. Then is depends on the type of music you like and what you are drawn to.

There are more articulate monitors and more rounded musical ones, if you are using a Pass which tends to the warm and bloomy side then you should look at more articulate monitors. 

You can look at smaller floorstanders with out very deep bass as well.

One of the most incredible speakers that you can get in this price point is the Quad Z3 roughly $3k or the larger Z4 at $4k, these speakers offer an incredible ribbon tweeter, a stunning midrange and thorow a huge soundstage. 

They would match the Pass really well. Would need to know more about your musical tastes and the rest of the system.

Also the point source of the ls50s helps make for better imaging especially in a smaller room in close quarters.

I'll put my 2 cents in for what it's worth
i have a pair of Greybeard KB/2/2 speakers and a small listening space. 
They are floorstanding. Actually, Larger monitor and attached stand. Two way with 7" & 1"  scanspeak drivers. I think they were in $5k range when new
Very cool. Mine are covered in black tile.They were also available with slate covering. Excellent Sound quality and detail at lower Amplifier power. Of course the bigger the room the bigger the soundstage. 
I beleive I read that Modwright uses a pair of Greybeard for their reference speaker. 
Apparently they were a company from the Portland area that was on the move, then the owner was diagnosed with cancer and the company disappeared. I'm going off memory here so no disrespect if my facts are not right
