$600These use the Visaton B200 8" driver; and response is listed as 53-20k (with a 44Hz in-room measurement).
Sensitivity is 96db, and I used them with both a Carver VTA-20S (aka Black Magic) and PrimaLuna ProLogue Five...to good result. Truth is, I don't even think they needed this much power; and if I could keep them, I was going to try a Decware SET next.
I think the price, is pretty fair; so buyer to pay s&h and any PayPal fees. Check feedback, as hiendpawn at Audiogon (long-standing and perfect; though I am just a box-swapping audiophile, like the rest of you...lol).
