How come Horn + woofer designs are not more popular?


A couple guys on my audio discord really love the JBL synthesis 4367 and feel that all traditional 3 way tower speakers suck because they have poor bass response and are generally shy sounding. What I wonder is how come the majority of speaker makes do floor standers that are 3 way as oppose to the Horn +woofer design of JBL?

Is there any downsides to the horn + woofer design? Can a horn convey microdetail as well as a Be tweeter like say from magic A or S line? They claim 3 way floor standers are just trendy. But is there anything more to it then that?

I'm leaving for an audio show in a few hours and don't have time to write you a decent reply right now, but will attempt to do so in about a week.

Audiokinesis, I would like you to tell me how you would make a two way hybrid horn speaker.
Not meaning to be glib, but the short answer is 'very well'. Duke's Dreammaker loudspeaker is a 2-way employing a woofer and wave-guide style horn, with a rear-firing complement as well. Its easy to drive and wide bandwidth; very neutral and musical. 
I'm not being facetious guys. I am trying to learn here. Way back I had Heresys and I loved them. In 1970 we did not have much for power. With a Dynaco Stereo 120 these things would rock. No deep bass but then nobody knew about sub woofers. They were three way. So let's assume we are using a 12" woofer infinite baffle and cross at 1000 Hz to a horn, what does it take to make a horn go from 1 to 20K with reasonably even dispersion and not sound like a goose honking. Duke's Speaker has multiple other drivers including three tweeters firing out back along with whatever is in the LCS box. It is anything but a two way hybrid horn speaker which to me means one horn and one woofer. I have never heard Duke's speaker and I am making absolutely no comment on their performance. So please Audiokinesis if there is a way to do this I would love to know. Like I said before my knowledge of horn technology is limited. Hear from you when you get back. 
Another issue that bothers me a little is the assumption that horns are more dynamic than other speakers. Horns are more efficient than most other speakers for sure but any speaker can be just as dynamic given enough power and power handling capacity. Horn speakers may have an absolute higher volume level at a given distance but very few of us listen at those levels. Our ears do have a pain threshold. In the end horn speakers are point source radiators and I personally do not think they present the music in as realistic a fashion as an ESL or Planar linear array. Maybe someone will build a horn version of Bob Carver's Ultimate line source. Think what that would look like:)
