Do these speakers exist?


1) Time and phase-aligned (thus 1st-order xovers).

2) At least 90dB/W/m sensitive, 6+ ohms nominal and 20W SET-friendly (flat impedance).

3) Two or three way.

4) Floorstanders - flat to 35-40Hz.

5) Under $10K.

The new Thiel 3.7 qualifies. Is there another speaker? I can think of several with all but one of those qualities but none with all of them.

A 20W SET on Thiels won't work at any volume higher than a murmur.

I think you need to check out Vandersteen. All their higher-end models fit your criteria - even #2.

I'm really not sure about this, but, Meadowlarks might. First order cross-overs while usually offering fairly flat impedances still have the reputation for being a bit challenging for amplifiers. SET's might not be the first choice for such speaker designs.
I have a K.C.S. 96db hi-eff ribbon, 2 way with fostex 12in woofers, 1st order with hovland caps alpha core copper foil inductors.Baltic birch cabinet 1 1/2in T ,Solid cherry ribbon mounts,28hz-40khz $1900 shipped.I have used on 300b set 9 watts with great results,built 6 pair this is the 1st prototype and uses better crossover than production model.Price incs frieght system is lightly used.
Ummm, I believe the Gallo Reference 3s match your criteria. Avaialable for WAY under $10k...
