Tall Tower Speakers for $10-14k

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.

Looks like Bryston 4BSST will be the best price / performance ratio.

7" short of making the 50" cut, but I find the Avalon Eidolon's the most visually stunning speakers I have come across. It does not hurt they are also phenomenally sounding, and well within your price range. Mine beat the Revel Studios and Verity Audio Parsifals I owned before hands down. Did I mention my Eidolon Visions are up for sale on audiogon?
