Success breeds repitiion and imitation.
But what does that show? That audiophiles dont care about sound but care more about how a speaker looks?
"Back in the 70s an engineer figured out..." sounds like 1000 other BS stories.And yes, anything that Kenjit doesn't approve of should be illegal (In Kenjitville).
If I was in charge of the speaker industry half of the speakers we see wouldnt be allowed due to inadequate sound quality.
