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?

Here's a quote from Ralph Karsten of Atma Sphere that you can find on page 2 of this thread. If you are concerned about my lifting it out of context, you can read the entire comment there.

So when I say I prefer the horns I do, its over mbls, Wilsons, Sound Labs, Quads, Magnaplanars, Appogees (and their current clones, which are quite good), Avalons, Dalis and many other excellent speakers too numerous to mention. Further, I don't expect horns to always be on top; all technologies improve and one has to be ready to pick up and move if you want to stay on top :)

If I had a pair of Magnepans, I would make sure I lived near a beach with big waves, so I could use them as surf boards.
LOL.

Weseixas since you say you've heard owned or have had much experience with the worlds greatest loudspeakers. Could you let me know brands of horns that you feel represented the best examples that you took the time to demo? You state [my decision is based on hearing the best of the best,] So lets hear it what are the best of the best?
