BBC ls3/5a's by Harbeth or whoever would probably work ok. Another possibility is the same sized Spendor S3/5. The same sized and sealed Harbeth HLP3ES might be a better speaker than those just mentioned, and its bass response and even soundstaging and imaging would be ok close to the wall, but it could be somewhat bright if too close to sidewalls and ceiling. The larger front ported Harbeth Monitor 30 is out of your price range and would also be somewhat bright in a small room. The front ported Harbeth Compact 7ES is closer to your price range, but I would worry about boominess because it has nicely extended bass in free space. Maybe if you had them up on really high stands, then of course you have a potential ceiling reflection problem. Maybe Charlie (danvetc), who has his Compact 7's in a small room, will chime in here. I don't know how close to the wall his are.
What I think you need is a sealed or front ported speaker with rolled off bass and rolled off top end. The Harbeths are extended top and bottom. The little Spendors may be a better fit.
Maybe the little Epos (M12? M15? - the model names have changed from ES11 or ES12).
