Suggestions for high efficiency speakers?

A) Klipsch is on my list to listen, especially as the Forte IVs were cited in the Stereophile Prduct of the Year article. BTW, my room is essentailly a 280" square with an ell to my right rear into another room of about the same dimensions.

B) I have to try Tannoy, why is so little written about them?

C) Budget? Say <= $15K.

Stanley, the RM25 Josephs are one of the outstanding bargains in audio and I've had them for maybe 18 years. What I'm looking for is that palpability of the notes that really high efficiency speakers do better than the 25s. They aren't really hE but my 20W amp has no trouble pushing them.

Thanks, verdantaudio, I think I met you a couple years ago at CAF. Those brands all ought to be good but aren't Avantgarde's really sensitive to placement? BTW, I love Art Audio, my Vinyl One is a recent addition and I am totally satisfied.

Thanks everyone for your suggestions this gives me much to work on to try to hear all these speakers. I'm not in a hurry, the Josephs are great speakers, so I can do a thorough job of auditiioning these.

Forgot to mention I have a Velodyne DD15 sub

Good entry, kirtgunn2, thanks to you and everyone else who'se weighed in on the subject. I have a lot of speakers to explore but I like what I have so I'm in no hurry.

Bass is not an issue for the Jota.

To follow up: I bought a pair of Charney Companions. I had forgotten I'd heard them several years ago at Cap Audio Fest when I think they had Lowther drivers. I was very impressed by their presence and the palpability of the sound but conventional wisdom had it that they don't do bass. While bass may not be their long suit my speakers with Voxativ drivers produce bass very clearly down to around 30 Hz. When I visited Brian Charney I immediately recognized the sound I had heard several years before. Five months later I am extremely satisfied.
