High Efficiency Speakers Your top 3 or more

I have not heard many like that actually.

Some I would like to hear are Avantgarde and Classic Audio Reproductions (I think their horns qualify though I do not know their efficiency specs).

Cardersound is a reasonably priced line that I would like to hear.

Of course the usual culprits, the Klipschorns (the only ones I have actually heard though its been a while).

The thing with these very high efficiency horns is they tend to be BIG! You have to have the right room for a lot of them, althoughif WAF is not a concern, I've seen some monster horns fit into pretty tight quarters!

Also Cain & Cain Abbeys. Very slick looking!
