Ohm Walsh Micro Talls: who's actually heard 'em?
"If you sit in the sweet spot of a conventional speaker, would the Ohm's differ if you dropped them into the same spot? IOW, is it only when you start moving out of the sweet spot that omni speakers start to shine?"Sweet spot is usually much bigge... 
Happy music...

This thread has rekindled my interest in es speakers.

Over sweet treble and midrange bloom..... Sounds enticing! 
Happy music...
Rite of spring is pretty upbeat as well.

Wouldnt two ohm or less impedance at high frequency be much easier for a ss amp in particular to deal with than if it were low? Way less power needed for high frequencybthan low. Or is it more complicated than that?

Es speakers are special and worth any special effort needed. Plus you have some good sidekicks here that can help to get them singing.

Theory helps one to play the game well, but ya still gotta play it. Autoformers in finished boxes showed as costing over a grand. A barebones version would be less i suppose. Es speakers can be pricey, so its all relative i suppose.

The ear sensitivity chart shows why what measures as flat response is not heard as flat response normally, It illustrates why what measures as flat frequency response may be perceived as bright. A lot of mass produced SS gear feature things like f...

I am over 50, and I know my ears like most older ears do not even hear much above 12khz or so like they used to when I was a young audio "stud". So getting flat response that works becomes a lot easier with age. Roll off of highs with ES speakers ...

As the ear sensitivity chart at the link I referenced above shows, human hearing is far from flat over the 20-20kz frequency range normally associated with human hearing. That means nothing that truly measures as flat will ever be heard as being f...

"And although I can't formulate a meaningful technical explanation, and I suspect that a good explanation would be a complex one involving a multitude of factors, my perception over the years has been that there is a tendency for those qualities t...

Autoformers cost more than many speakers themselves. That's a factor to consider in the equation that can't be ignored.

" The argument that there is too much variability in the sound of live to establish a benchmark is nonsense; there is much more that is consistent than there is that is different. "Agree with Frogman on this. All live music has certain things in c...
