What’s a 10k to 15k speaker from smaller company that performs well?

They're $6495, but after six months, I'm still happy with Sonist Concerto 4 Gen 2.  Solid wood, high WAF, very efficient, 27hz-45khz, great soundstage, very transparent without being edgy.  What's not to like? I had 10k budgetted, so used the savings to justfy a magical tube amp.  I added 3rd party jumpers and feet.  Hard to audition.
