Cornwall 4 vs JBL horn under $10,000


Want to try a horn speaker with new Wellsenton R8( upgraded tubes) amp. My first experience with tubes and horns. Have read a lot about Cornwalls 4 and was about to purchase but thought about JBL’s. Want to stay under $10,000 and new or used.Any thoughts or recommendations?

I own the 4367s. They are not appropriate for the Wellsenton R8, requiring much more power. I do not know about the Cornwalls. 

+1 Volti.  Possibly not a fair comparison, but I upgraded from Cornwall Series 1, which I loved for over 13 years, to a used pair of full Volti upgraded Klipschorns.  Not even close!
