High impedance Speakers


I've read here and there about the benefits of using speakers with high impedances, especially with low power tube amps, but there don't seem to be a lot of them out there. I've identified a few:

Coincident Victory, SuperEclipse, TotalEclipse: all 14 ohms
Coincident TotalVictory: 10 ohms
Omega TS33: switchable 4 ohms/16 ohms
Zu Cable Druids: 12 ohms

Can anyone add to this list?

The Alon Lotus SE are also high impedance, and supposedly work quite well with SET/OTL tube amplification. Great company as well.
Soliloquy 5.0i is 10 ohms.
Soliloquy 6.2i is 12 ohms.

Of course these are nominal values, but Soliloquys have a reputation of working well with tubes.

Also there is always the option of the Zeros (speaker impedance multiplying autoformers) by Paul Speltz. You can find these at http://www.zeroimpedance.com.
Classic Audio Reproductions makes two 16 ohm speakers, the T5 and the T1, which are both moderately high efficiency too (95 and 97db respectively).
Ah, Ralph, now that I see you have added your wisdom to this thread, it popped into my mind that you are the longtime guru of this topic!
