Is the most efficient speaker the best speaker?

Mapman, the simple fact is that any speaker that has high efficiency conforms to the Power Paradigm unless the designer went through extraordinary steps to prevent that.

All SETs and most zero-feedback amps are also on this paradigm. Yes, it is a 'minority' technology but in the opinions of the designers of such its the technology that offers the possibility of real music, as opposed to something that sounds like a stereo.

Now the Power Paradigm offers that possibility of being that much closer to the music. The idea is that the technology is totally committed to the rules of human hearing, which I think all of us can agree is the foundation of audio; without our ears we would not play with audio gear at all.

OTOH the Voltage Paradigm is all about looking good on paper (IOW pays little attention to human hearing rules), which our ears could give a damn about.

So going to higher efficiency is clearly an access to transformation in sound quality. Of course its better!

Atmsphere, of course that is only your opinion, many if not most, have come to the opposite conclusion.

I believe it was Earl Geddes who said, "Science is not a democracy".

What he meant is simply this: Facts are facts and are not subject to voter approval.

No matter how many fools choose to disagree with him, Atmasphere remains correct in his statement.

You guys are missing some key points. All speaker designers want to have high efficiency but you can't always get it without compromising something else, like frequency response or a changing impedance. As in most engineering, you have to make choices and it's up to the designer to make the changes he/she wants, efficiency is one of the first to get compromised.

Prove it.
