I don't want to mention any other brand names but there are some brands that when I put the individual drivers alongside each other I can't help but develop a bias regardless of how the finished product sounds. Just look at the woofers in the new persona series! In the 90's the stuff I could afford it was easy to predict how a speaker would sound by the dome material and anything with a 'waveguide' was considered just another form of horn loading that came with their own set of calculable issues that always ended up with cupped hands sounding voices. I don't think most people could tell what a modern well engineered speakers drivers are made out of by listening to them. and the more I drag different hi-end speakers into my listening room the more alike than different I find most of these speakers sound.
