Seeking horn array loudspeakers with a maximum price of $17,500.00 per pair.

Not sure why you want horns with your powerful amp.  In your price range, horns can be difficult.

I’d second the Volti’s, or maybe Charney’s.  I have Klipsch Cornwall’s, but they may be too cheap for your situation.

JBL 4367 see here.

Do not get the Volti... Grainy sounding treble and doesn't have bass extension.

Get the JBL 4367. I second that recommend

You can call JBL to ask if there's a dealer in your city @kjl1065 

Volti & JBL good recommendations.  But see if you can have a pair of Klipschhorns auditioned in your home. Spooky 3D soundstage.
