In real instruments and voices are very direct to point out and very small in proportion. At shows you often hear that voices become bigger and less sharp focussed. I would never choose for this. It is less realistic.
Why not horns?
I've owned a lot of speakers over the years but I have never experienced anything like the midrange reproduction from my horns. With a frequency response of 300 Hz. up to 14 Khz. from a single distortionless driver, it seems like a no-brainer that everyone would want this performance. Why don't you use horns?
