Best high-efficiency speaker under 10K

I was not unfortunately able to hear the more expensive Tonian models. I owned Beauhorns and they are very good, but pretty bandwidth-limited as you said. What they bring is smoothness missing from almost all Lowther speakers. Front-loading the drivers brings up the low-mids to eradicate the peaky mid-high mids.

You better look for the real thing. Real HE no plastic cones.There is a certain minimum point of sensitivity to deliver the nuance & dynamics and it is far beyond the 92dB.

Just for inspiration:

The above mentioned tweeters are a subject of an added upgrade if you feel the need for. (I do)

used Avantgarde Unos should be available in the $10K range. Full range, 103dB sensitivity; but you must be able to sit 12' away in your room.

I would also look at the Tannoy Dual Concentrics (with the pepper pot wave guide). I picked up my used Kensingtons in excellent condition for $4500 earlier this year.

Hello fellows, I just had a chance to listen to a pair of beauhorn that a local gentleman owns. I first listened to them with his electronics ($65K worth of equipment..a nice audio note SET power amp and a battery powered preamp whose brand I don't recall), and then with my own Lavardin IT. It's a very interesting speaker, the sound is palpable, 3-dimensional. It really looks like you're a few feet away from Ray Charles. Of course the extension is limited, especially the low frequencies and I did not like the use of REL subwoofers (after the first tune I asked him to diconnect them). The way he positioned the speakers made for a very intimate experience with the speaker or player or orchestra. it's an incredible experience but I probably like a more distant perspective, which can be had by simply repositioning the speakers a bit closer to the walls and the listening position a few feet farther away from them. By the way, these speakers used an optional supertweeter. I tried them both with and without the supertweeter. There is some difference but I am not sure which option I like best. It probably varies with music. As for my Lavardin vs. Audio Note, well, it was day and night. The AN was warmer, more textured, quieter. The Lavardin was drier, more extended, leaner. Through the AN you have the impression to almost touch the players. The Lavardin puts you a bit farther back in the audience. Both of them did very well. Which one is best is a matter of taste.
