Wilson's Chronosonic XVX loudspeaker over 3/4 of a million US dollars

It is hard to imagine any designer believing that lower speaker impedance is a good thing. My guess is that the higher power output of many amps when driving lower loads is (was) the main motivation. 

It is hard to imagine any designer believing that lower speaker impedance is a good thing.

Right??

Those are some of the fugliest speakers I've ever seen, and this is from someone who happens to be a Wilson fan!

Those Wilsons are simply irrelevant.  True innovation with speaker design is taking place many places, but always far from Provo.

When Wilson markets a PTS to match your Ferrari, they mean it. That is kind of the market for this except the question is which of my Ferrari's? According to Stereophile it is $329,000. The limited oligarch-grade WAMM Master Chronosonic is $850,000.
