Tall Tower Speakers for $10-14k

The Canton is a good choice but consider, also, the Aerial 7T and Adam Audio Classic Column as alternatives, if you don't mind saving some money.

Oh, and how could we forget the Magnepan 20.7? A whopping 6'7" tall for a relatively modest list price of $13,850.

Dunlavy sciv,v,or vi's are big;maybe soundlab A1px,u1px,m1px if you have proper amplifiers for them,Rockport and there are others.

fourfour what amplifiers are you going to drive these speakers with?

I own Zu Def 4s and like them a lot. They are full range, have integrated subs, are 101db sensitive, are just shy of 50" (I use small ebony footers to protect my hardwood floors), and are right at your price point. Mine are in gloss black; the quality of the finish is exceptional, and gloss black is perfect for my decor. However, you can customize the look in an almost unlimited number of ways in terms of paint, veneer, base and surrounds, etc. since each speaker is built to order.
