Good Speakers for Rock and Roll Under 15K

After hearing Cornwall III and IV I felt they were really great with R&R. Not so much with other genres, but terrific with rock.

Just a hair over budget at $16,500 (used pair on here for $8k right now) the JBL 4367 is my favorite rock speaker I have heard to date. Super dynamic with smooth treble that is easy on the ears. Great texture and impact in the bass. They could go lower and I still add subs, but I need full range bass to be happy (a personal thing). I have owned speakers I thought were good for rock but ignorance is bliss and they have been totally eclipsed by the 4367. Not just a rock speaker but simply good. 
 

The treble is also adjustable which makes a much bigger difference than the numbers would indicate. I am down 0.5db on the UHF.  
 

Measurements to back up the good impressions too. 
 

Rock with an 845 tube amp?  Klipschorns. Maybe Tekton. 

Planars are generally not ideal for pop music otherwise take your choice with that budget. I’d be looking at KEF meta or Revel personally were it me.

I like Marten speakers from Sweden. When auditioning against Dynaudio Heritage Special and YG Tor, the Marten Oscar Duos hit me immediately as better rockin' speakers; I ended up going for the even higher model, the Parker Duo, just because the upper bass/lower mids are amazing with the larger speakers. But I listen to rock and reggae exclusively and for me, these are great.
