Phusis, I too went through discovering the speed of compression drivers in horns and once came very close to buying a five way compression horn array from GOTO. At the time I had Avantegarde Trios and learned a lesson about an array of horns. Unless you are quite a distance from them, instruments will switch positions at different notes. In short, not having a fifty feet long listening room, I could not enjoy either my Trios or a five compression driver horn system. I have seen pictures of Japanese audiophiles sweeping the dust out of the mouths of their horn speakers with listening chairs only about ten feet in front of them. So apparently some can tolerate this, but not me.
I have had single driver horn systems, full range electrostats, line arrays of ribbons and dynamic tweeters and midrange drivers, horns with and without compression drivers, and many dynamic driver systems. What I think is needed is the counterpart to a microphone, namely a point source capable of 110 db peaks and flat from 20 to 100,000 Hz. I know of no such device.
