What is the best speaker for a smallish room?


I currently have a wonderful EAR 890 power amp, a Klyne SK-6 pre-amp and a pair of Piquet modified Quads. It's a great combination but I'll probably need to relocate to a smaller room -- 11 x 15 or so. I am thinking about substituting the Quads with another great speaker. The quads are just great, although they move less air than I would like them to. I thought about a pair of Sonus Faber Extrema, but I believe they like large rooms. I am open to a bi-amplification solution. Thanks.

Ladvid..I hear you about the WAF on the Green Mountains. I always read about the hype of the sound of this company but never heard them until RMAF last year. I didn't hear the smaller Picos but I did hear there larger floor standers and I remember finding it hard to leave the room. Thats when you know the sound is good is when you have so much to see at the show but somehow seem drawn to stay in a resilient room.
Harbeth speakers sound great in small rooms. They are designed and tested in small rooms. Check out the Harbeth web site for more info.
I would 2nd Harbeth the HLP3es2 for a small room. These have great mids and sounds very holographic. Imaging is fantastic as well.

Thanks for all your advice. I ended up buying a pair of Reference 3a Di Capo i (although I also liked Thiel 2.3). I was intrigued by the absence of crossover. I will not sell my Quads though...will keep you posted on how the sound. The reviews I have read are quite promising.
hummmm - sounds interesting.
Do let us know what you think of the speakers, and if you can get them sounding good in your room/system! The reviews sound promising.
I'm very interested in simple crossover, high efficiency speakers. And, when you come across affordable smaller monitors like this, I'm always very interested in checking em out.
Keep us clued in!
