Why did you choose a horn based loudspeaker?

"Plus I find a horn loudspeakers to be interesting in design and in appearance."

Probably the main reason I would.

Full range high efficiency horns also tend to be relatively large though, which is their biggest barrier for most these days where space is often at a premium and other more compact good performing and readily available options exist as well I suspect.

I believe I can achieve similarly great if not exactly identical results with or without horns though. It's more about how one mixes the soup than any one particular ingredient, I have found.

Also worth mentioning that high sensitivity speakers like most horns are extremely sensitive to EVERYTHING, not just the music. That includes noise, distortion, or any kind of sonic abnormality. So getting things just right upstream is more critical than ever. Not always easy to accomplish or maintain over time. That's just one reason why many horn demos might underwhelm or cause fatigue faster.

But, if you get it all right....then you have something. I have heard some really good, large expensive horn systems and enjoyed them for extended demos, but have never lived with any to-date for the long term, whichis what matters in the end.
