The best speaker for a small room...at any price point.

Klipsch Heresys with a tube amp like the Atma-Sphere M60 would be perfect. A smaller Pass amp like the XA 60.8 would also do.
You can put the Heresys right up against a wall. You can also put them up on stands at ear level. Subwoofers in a small square room will be difficult. You will certainly need room control. 2 JL Audio Fathom f112s would be fine. Put them tight into the corners of the front wall. 

Well if it is electrostats you want then go with the Sanders Model 10,
The panels cross to the transmission line sub at 175 Hz which will allow them to operated 2 feet from the front wall. You will need to put acoustic foam behind them. No big deal. roberjerman I sold Walsh speakers back in the 70's and they were painfully colored back then. Hopefully they have improved them since then but it is a difficult concept. I love the idea of no crossover. Except for subwoofers x-over are nothing but trouble, A necessary evil.
