Horn Speaker Recommendations


I am looking for your feedback on what Horn speakers I should consider in the $15k-$40k price range.  Please describe the rationale for your recommendations.

with all the horns I've heard,  there is wonderful sense of realism as far as dynamic shading is concerned....at the expense of soundstaging, etc.
The other factor I have is I am building a large listening room.  It will be 20 x 35 so the speakers need to fill the space.

JBL M2 is one of the best speakers I have listened to. I think JBL 4367 is based on the same. 
audition jbl 4367 at the very least also i think there is a pair of dd67000s for sale on audiogon for under 40k
JBL DD67000 is the most dynamic modern horn speaker with pretty high efficiency.

You can drive it with low power tube amplifier(10-40Watts).
