High Efficiency Speakers Your top 3 or more

Noted.

WAF is a major inhibitor for me with these high efficiency horns because I would like to target them into my wife's sunroom where the Dynaudio monitors sit relatively unobtrusively today

Mapman,concerning the WAF,the SQ H-10 horn speakers are fairly compact.Here is a review of their larger brother,the H-15:

Also I have heard several of the single driver Omega models.While the large stand mount Superhemps were my favorite,their small bookshelf and floorstand speakers were also quite good!

I owned AN/Es (HE Kit 3s - basically equivalent to the factory SpE HE) and TL-D1s together for several months and went back and forth between them often. I think I can speak to their differences pretty well.

The Tonians are significantly faster and more open-sounding - they have a way with microdynamic finesse, esp. with percussion, I have basically not heard exceeded. Spellbinding.

The AN/Es had significantly lower bass as well as quite a bit more midbass energy. I also thought timbre was slightly better. Although the Tonians are never, ever shouty, being completely smooth and balanced, perhaps the AN/Es hemp driver gave slightly better harmonic density.

Although I preferred the Tonians for jazz I felt the AN/E was the slightly more well-rounded speaker.

Then I realized neither was really ideal for my huge room

great thread ... curious what you are using now Paul that you have moved past the Audio Notes and Tonians.
