High efficiency speakers


I am looking for medium size high efficiency speakers. How would you compare trenner & friedl RA and Devore orangutan 0/96? Any others I Should be looking at that similar or smaller footprint and can be driven sufficiently by 8w 300b SET? Thanks

In that price range? Zu and Audio Note.
Coincident

There is a nice set of reviews on high efficiency speaker done by Jack Roberts on Dagogo.com plus a full review on the Devore's which is a nice read.
Tannoy Kensington SE.
Line Magnetic.
I'll second the rec's for Coincident and Zu. I've owned Coincident total victory's and currently Zu superfly supreme. Both are excellent. The Zu does have a smaller footprint.

One suggestion would be to try the speakers with your amps as their only 8 watts/channel. On paper it should work. In reality the combo may not produce the dynamics/loudness your looking for depending on musical tastes/room size etc. Zu has a 60 day in home trial.
The Line Magnetic 755i speakers fit the bill perfectly.
I own them for over two years and can personally attest to their affinity with the Shindo Cortese and Corton-Charlemagne amps.
Make the effort to hear them.
IMO, you should also consider Hornings.
Not sure about your price point but you should add Daedalus to your list. I heard the new Muse at CAF this weekend and it was exceptional. He has a number of other medium sized floor standers that are worth a look, including the Athena. All are very high efficiency designs.
Tekton Lores come to mind immediately. They get great reviews and the prices are very reasonable...

Not sure about your price point but you should add Daedalus to your list. I heard the new Muse at CAF this weekend and it was exceptional. He has a number of other medium sized floor standers that are worth a look, including the Athena. All are very high efficiency designs.

Just for the record, a 'high efficiency design' is likely going to be about 100 db or more. The Daedalus speakers are 4 ohms with a 96 db sensitivity, when you do the math that means their efficiency is 93 db, which is not high efficiency, rather it is a moderate efficiency. Despite their impedance, they are lacking severe phase angles and are thus a relatively easy load for tubes.

Here's the math:

Sensitivity is 2.83 volts at one meter, efficiency is 1 watt at one meter (into 8 ohms the two are the same). However 2.83 volts into 4 ohms works out to 2 watts. Doubling the power from 1 watt is 3 db; IOW subtract the 3 db from the 96 db figure and you have 93 db efficiency.
Ralph (Atmasphere), I certainly agree with your math, and in fact I've made the same point in a number of past threads about the 3db difference between 2.83 volt and 1 watt numbers for 4 ohm speakers. However, I'm not sure that you are characterizing the Daedalus speakers accurately.

First, as far as I know no Daedalus models are 4 ohms. At present the Daedalus website doesn't appear to specify impedances, but my Ulysses, which were the latest version prior to the recent introduction of the ".v2" version, were spec'd at 6 ohms (and 98 db). Other smaller models were spec'd at 8 ohms. And while I haven't ever seen an impedance curve for any of his models, I recall Lou Hinkley of Daedalus stating that the impedance of my version of the Ulysses is 6 +/- 1 ohms at all frequencies above 100 Hz, rising to a peak of 10 ohms in the deep bass region.

Second, the 96 to 98 db specs of the various Daedalus models are all specified on a 1W/1m basis, not 2.83V/1m.

That said, I would not suggest to the OP or others that an 8W SET be used with any of the Daedalus models, UNLESS no high volume listening is intended, AND recordings having particularly wide dynamic range (such as well recorded minimally compressed classical symphonic music) will not be listened to, AND listening distance and room size are not large. As you (Ralph) have rightfully pointed out on many occasions here, SETs will not perform up to their sonic potential if they are driven hard.

I heard Tanner & Friedl and Devore Orangutan in RMAF 2013 in different rooms.

Preferred the Devore Orangutan by a large margin. More resolving, more involving. Admittedly the electronics driving the two speakers were different and so were the rooms of course.

Hope that helps. I also preferred it to and Zu, Coincident (TV 2).

Just my two cents.

Anyone has experience with Ocellia?
While not a fan of Daedalus loudspeakers, sonically, I've been around them enough to know they do play fine with 8 watt 300B SET amplifiers.
Edoir I had the Ocellia Calliope .30 Twin speakers, great sound awful customer support! PHY driver is a wonder cabinet is a DYI project at best. (IMHO)
Sksos1,
I believe Ocellia has superb products, it's disappointing to hear you had service issues with them. I assumed Samuel would have that aspect covered as well.
Charles1dad,
Sonically no complaints just a wonderful sound, quick and transparent but when I had an issue (and no fault of Ocellia) what a hassle.
In hindsight though couldn't be happier with my Acoustic Zen Cresendo speakers. Music has never had the presence and focus as with these transducers.
