High Efficiency Speakers Your top 3 or more

Tvad,
can you post a link, or just mention it again?

Isn't it true in general that the higher the efficiency of speakers, the more sensitive they are (in general) to minor variations in the signal fed them?

I've always assumed that deficient setup is the reason why many do not take to Avantgardes, because they are perhaps one of the hardest designs to get set up right.

Some may take to them just due to their "avantgarde" appearance alone and not have the ears or will or ability to set them up correctly.

I'd be surprised if I would not take to their sound assuming they have been setup well. I would also not be surprised if the setup in many cases chased me out of the room.

Proper set up is key for most speakers, just perhaps to the max for a design like Avantgarde, which push efficiency specs to the limit I believe.

Tvad, the Audionote speakers IMHO do not represent high efficiency speakers, although I do like them once Peter has set them up.

Mmike84, My favorite high efficiency speakers are: the Beauhorn Virtuousos and the Exemplar tractrix horns. I also thought the old Maxhorn using Feastrex drivers was excellent. I am once again out of my high efficiency and SET period and back to my modest efficiency multiple driver with fairly powerful SS amp period. What I really want is a single, one inch, full-range driver capable of 20-20k Hz speaker that is 103 db efficient. I haven't found any:)
