Is there a perfect speaker?

A perfect speaker is the one with zero harmonic distortion, ruler flat frequency response from 0Hz to 100KHz (some may argue it needs to go even higher), zero phase shift, 360 degree uniform dispersion, unlimited dynamic range, 100% linearity and 100% efficiency.

At the current state of technology, no speaker even come remotely close to any of these properties and I doubt I will see one in my lifetime.

Sidssp~ Even then there are some who would still prefer Bose.

In order to find the Perfect speaker , one must have the Perfect listening room , and 100% pure AC inlet power. Good luck.

What everyone else said. Speakers more than some other parts of the chain, all have mutually exclusive choices. I love my Daedalus DA-RMas and the test, as others have said, is that I don't want to stop listening and wonder sometimes, what better, would sound like. Are they perfect, no, by going for high sensitivity, you have to lose some base extension. That's fine by me, it means I can use low powered SET and other Class A amps that I like.

Some of the top brands of "High end", mega expensive speakers, unlistenable, for any length of time. I'm not criticising, but am thinking of Wilson and Focal speakers here. They just are'nt for me.

If there is a message, when you've found what your looking for, stop looking and enjoy.

"Perfect" is a concept not a reality so no, there is no perfect speaker.
