I could not disagree more..
@mofojo Big myths die hard. So this does not surprise me- I get pushback on it all the time. But it comes down to something very simple, which is can you find a designer who can say what parameters exactly will favor a certain genre?
I've been doing this 45 years and got an engineering degree early on. I know a lot of designers and none of them make any claims to this effect. Since I design amps and preamps I see things a bit differently, thru the eyes of my test equipment. Once that signal is in the amp, the amp does not care what it is, it just amplifies it. I suspect the same thing for speakers- they have no taste, they just move as the amp tells them.
