I would try Tonian Labs TL-D1 speakers. They use a single 8' Fostex driver and ribbon super tweeter, having 8 Ohm impedance and 95 db sufficiency. supreme treble, life-like midgange, very good organ timbre and all these for only about 1500$. Indeed very impresive speaker; perhaps the best in this price range. Check it in www.tonianlabs.com.
