What traditional dynamic speakers deliver a sonic signature similar to a horn speaker?

I would mention Tannoy, in 12" and 15" Dual Concentric size. High Frequencies are horn driven.

there are many very efficient conventional driver speakers, using very lightweight cone materials that sound ’horn like’ and more or less 'shouty'

page down, user @br3098 provides an excellent list of makers

Tekton Moab, Encore, and Ulfberht are similar only in the horn-like dynamics and ability to throw a huge expansive stage. Other than that they are not shouty or colored. But then neither are the very best horns.....   

While you are at it they also have the speed of ESL, the seamless integration of a Maggie, the pinpoint imaging of a mini-monitor, and the big physical slam presence of a big speaker that moves a lot of air, which they are. They do however suffer from one fatal weakness- they are not expensive.

Zu Audio, ALL, Omen Defs are 101dbB@1watt, sound great. +1 Tannoy.

If you like the horn sound, why not just get horns? Too big for the room (or the little lady ;-) ?
