Current amp vs Voltage amp

Al, my take on this, is that on speakers with varying impedances(all?), such ss amps are more likely to provide more linear output from those speakers. Please correct me if I'm mistaken.

Al, the wouldn't sensitivity of the speaker vary along with the impedance?

If we put aside the issue of damping for the moment, and so long as such a ss amplifier has the required output power, such a ss amplifier would almost always be able to provide more linear output regardless of whether they are ESL's or dynamic speakers, and that would hold true whether or not the impedance swings were wide or not. Whether or not thus would always be audible is of course another issue.:-)

Please forgive me, as I don't seem to understand.
I would think that if the speakers impedance varies, and as such it's sensitivity varies, I would think that unless the amplifier can adapt its power output appropriately, the speakers frequency output response will deviate from linearity.

It seems that it is easier to design a speaker with a consistent impedance if the impedance is low rather than high.

Because with available amplifiers capable of dealing with them, it might allow the speaker designers to put more emphasis on other considerations?
One could also ask why amp designers choose not to build amps that can deal with such loads?

Often as the speakers impedance changes so does the the sensitivity, and that should correspond to flat frequency response from such a ss amp.

I have to agree with Bombaywalla. Some manufacturers of ESL's specifically made/make ss amps for use with their speakers, Acustat and Sanders come to mind. Many ESL manufactures use ss amps when demonstrating their speakers. I remember a particularly fine demonstration of Martin Logan's with Threshold amps.

I think Hifigeek1`brings up an excellent point!

Powered speakers can be sold with separate power units chosen specifically for the task at hand, the way some speakers are sold with separate cross-overs, or have upgradeable power modules. I typically (always?) prefer systems that have speakers with low impedances rather than higher impedances. Historically speakers with lower impedances are more likely to be able to produce wave form fidelity than speakers with higher impedances. There are many good reasons for speakers to have a low impedances and the market place has proven this for a long time now.
