Best speaker on used market around 10,000.00

I second the Uno's or Duo's.

I have owned C4's/N800/Andra's/Sanus Faber/Aerial/Uno's
And dozens of others. Maybe I did not define exactly the advice I was seeking. Sorry.
A speaker while sitting 12-15 feet away with a 100 watt amplier is capable of moving air to your chest, and still maintaining a stable sound stage and natural tonal balance.
Thanks again Curleyques

The thrill of the hunt! I know there are tons of variables, being from Kansas City we have limited stores to audition products. Just looking for thoughts.
Thanks Curleyques

so you need something with very big woofers ,somenthing like that,horn type sensitive speakers

Curleyques, what ever happened to Primus Audio Pleasure in Kansas City? That was a great place.
