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?

The very best horn designs run at about 3% THD when played loud and this will distortion is audible and in treble."

Now where did that come from? The best horns are a lot lower than that figure. Please document where "the best horns" are this high in distortion.

Horns are natures amplifier.

A horn loudspeaker done right is hard to beat on many levels some of there attributes being: better dispersion than non-horns, 5dB increase in bass, can be used to increase a driver set efficiency, look cool.
Does anyone happen to have any experience with JBL 4550 speaker systems? I do find a few owner/user pictures of their rigs featuring such on the web (images) and they only direct to sites in Japanese or Chinese.
The above reference to Art Dudley's article on sucky bass is a valuable post referencing one of the great articles that I have read on the state of speakers as well as the psychology of audiophiles and their speaker choices (that has led to some truly overrated and overpriced speakers nevertheless sell.
I like the looks of the new JBL Studio 530 monitors. Would like to hear them.
