I'm not sure why he thinks it's a rant, or how starting his speaker company is going to change things.
His points are right on target. And he gives a fair appraisal of the virtues of some of the renowned speakers that fall into the category of low impedance loads. He's correct that the standard spec has changed, and that it is now more complicated for the consumer.
On the other hand the current spec is more accurate as speakers have typically never had a static impedance, and it really isn't too difficult for the consumer to calculate what amplification is appropriate so long as they know the minimum impedance. And while it's true that amplifiers tend to distort less into higher impedances, it's also true that amps and speakers prefer to work with more linear impedances, and that can be done by lowering the impedance but not by raising it. Furthermore, amplifiers that double down, or halve up with impedance do so with concurrent sensitivity changes, and therefore are better at maintaining frequency linearity. Also lower impedances are more immune to noise infiltration. Originally replacing larger speakers with smaller ones and replacing less powerful amps with more powerful amps allowed for more domestic acceptance of hifi. Now with home theatre and surround sound it's even appreciated more.
