High Efficiency Speakers Your top 3 or more

haha, tastes differ so much. I have the Zu Def. 2s and wouldn't trade them for anything on the basis of sound quality. On the other hand, I have a friend with a dearer system than mine based on big Coincidents which I simply can't stand. The bass alignment is just wrong.

The Defs DEFINITELY can fill a big room on In Rainbows, in their sleep, on a small amp. Like a 45. I don't consider them rocker speakers though, it's weird. While they sound 'good' with any competent gear, they have a 'great' level which takes a fair bit of tweaking to attain.

Any of the 3 Oswalds Mills Horn speakers, KCS Loudspeaker - Sea Exotic/Raal ribbin(i own) & Serious Stereo Altec horn.

The Zu series of speakers are very efficient and easy to drive--plus they give tremdous value.

The Devore line of speakers, while not as efficient as the Zu's are incredibly easy to drive with low-powered tube amps and sound wonderful. The are probably my favorite line of speakers and all of them at their various price levels give incredible sound.

If somebody can show me a SET based system that can deliver Radiohead's "In Rainbows" with the authority and rock solid iron grip in the low end that I hear currently in my system running the (not so) big Bel Canto Class Ds, in a typcial sized listening room, I will be gladly convinced.

Hi Mapman, my Parmenter Fat Boy horn speakers (using TAD professional drivers) with either the Lamm ML2.1 now ML 2.2 or my Parmenter GM-70 SET amplifiers plays all types of music with authority. Shapeshifter, Pitchblack & Salmonella Dub really sound wonderful on this system, not a big Radiohead Fan sorry.
