Best high-efficiency speaker under 10K

Tekton Double Impacts are a 4 way 98db/4 Ohm load floor standing speaker.  I drive them with an 8wpc 300b SET, but many drive them with 2-3wpc 2a3 amplifiers to satisfying levels.  They compare to speakers much more expensive than their $3300 price, but if you want to spend more you can always step up to the Double Impact SE for $6500 or the flagship Ulfberht for $12K.  The reviews confirm what many owners already know which is that these speakers are giant killers and they present the most coherent top to bottom wall of sound you likely will only find in the best electrostatic or ribbon/planar speakers.  They are a 4-way design using a novel circular tweeter array that acts as the midrange with the center position tweeter producing the highs along with 2x ported midbass drivers and 2x ported 10" bass drivers. There's an Audiogon group that's very active with countless reviews by owners along with a world wide group on facebook. Just search on Tekton Double Impacts.   www.tektondesign.com  

Without a doubt top of line reflector from reference 3a...call tash owner ref 3a. Its the sound of raidho for one third price. 

@bache Sorry forgot to hit the notify button. Here is a link to Charney audio with current pricing.

I concur with rodge827. As a new Charney owner I am amazed! Give them a listen/purchase if you can.
