Quad ESL63s are pretty lively, and not too much money.
The updated version, model 989 would fit into your room, and probably give you some fairly high sound pressure levels.
Be advised that most modern ESLs have current limiters that will keep the diaphragm from touching the stator elements (which can cause instantaneous failure and bad smells when the smoke gets out)... and this may limit your satisfaction. Quad also makes a killer amp that is under appreciated, designed to handle the squirrelly load electrostats present.
Quad model 909.
That being said, I've recently experimented with older Definitive Technology speakers, which are dipoles. The BP-10 is a sleeper.
Wonderful soundstaging, tremendous dynamic response and good musical fidelity (not the last word in detail or imaging). They also play DEEP.
Careful about the 989 when doing rock. The protection circuit kicks in and turns the speaker into a 0 ohm dead SHORT when hit with a transient (high frequency transients actually triggers it more often than bass slam based on my experience).
Also check the input coupling cap if you can when buying older units.
Mine (220uF) recently measured a nifty 5uF (deterioration? failure?)
Have apair of BP10's.
They're pretty colored sounding in stock form, but they can be easily modded & the original drivers are inexpensive. they can definitely rock without a sub. I wouldn't use them for critical listening, but they must serve some purpose since I've had 'em since '94 and change my mind every time I think of parting with them ;)
Please elaborate on the modifications.
I put a felt ring around the front tweeter, but haven't touched the xover.
