Most high-quality loudspeakers are 4-Ohms

To my ears, most high-quality loudspeakers are lower impedance loads.

If you are only used to listening to systems driven by big, high current SS amps, you might that it is true. Many good, multi-driver speakers that mate well with SS amps have low impedences. However, there are many very, very good speakers with high impedences. They tend to mate well w tube amps. See for example, Vandersteen, Merlin, Coincident, Silverline, Classic Audio Reproductions, Dali Megaline, Horning, Audionote.

Swampwalker, I don't consider the Vandersteens to be high impedance speakers and there the only ones of those that you've suggested that I've heard and appreciate. While I haven't heard them all, some of the other I down right dislike. But, that's just me, YMMV.

NO.....

Nope. But you knew that, didn't you :)?

Well, sort of, but was not quite sure. ;) I had it direct quoted from somewhere without much context. How about "there are more high end speakers with 4 ohm than 8 ohm?"

When I had relatively cheap amps, I could not find anywhere about power ratings (RMS) mentioned for 4 ohm in their specs. All were listed for 8 ohm.
Most mid-high end power amps seem to have ratings listed for both 4 ohm and 8 ohm.
Most relatively cheap speakers I had (including Klipsch KLF-20, B&W 603 S3, Celestion Impact 20, ...) were all 8 ohms.

So, I was wondering if the low impedance has to do with high end speaker design in general. Of couser, I agree that there are many high end/high quality speakers with 8 ohm, so there must be exceptions.
