Red is a exciting color, horns tend to be exciting sounding speakers. they just go together like big horsepower and fat tires.Why are horn people so much into bright red horns? I can imagine what a psychologist might suggest it represents.
Agreed, I believe it has something to do with the large wavefront launched by the larger horn mouths and how they couple to the air. That combined with the usual high efficiency-lower distortion at any particular spl that often gives them a "live" presence factor. Good dsp might be just the thing to smooth out the coloration's that so often have come hand in hand. In this case I'd still prefer to see a large horn covering the bass range down to 50hz or so, though size then becomes a very real problem.My experience is that horns do sound different. They can have a certain rawness, a certain grunt and dynamic punch, that is special. It sounds more live, in a way. Dynamic speakers usually sound "smooth" in comparison.
Could never afford these but I'd love to hear them.
