Dcstep,
If you ever get up to New Hampshire you'd be welcome to come by and hear my Edgarhorns. All speakers have some colorations and these are no exception. However, you will not hear any midrange honk. I also did not hear that from Azzolina horns. I also own a pair of Acapella La Campinella MkI's and with the right amplification these also do not exhibit any honk.
For to original question, I don't know if horns are gaining popularity but I think high efficiency maybe gaining slightly more popularity in the 2 channel music world. I think lower efficiency and big wattage amps are still the favorites in the HT and multichannel world.
