I ran mine in a horizontal biamp config with a pair of sunfire signature stereo amps ( 1200 wpc @ 4 ohms).....very good results.
I changed to two pairs of Carver Silver 9t monobocs ( 900 wpc @ 4 ohms )in a biamp setup and it has been head and shoulders above the biamp setup witn the Sunfire amps. While the Sunfires were good, they didn't deliver the bass slam that the Carver monoblocs do. The bass with the Sunfires sounds "round" compared to the slam I get from the Carver monos. I am using an Audio Research Ref 2 Mk2 tube preamp with Signal Cable interconnects and speaker cable.
If you can afford to biamp, please do...or, buy as much power as you can to throw at those beasts.
I tilt mine back and I don't have a problem with tweeter harshness.
I have owned the the Kappa 7 and Kappa 8's also...never had a problem with the tweeter being untamed...I've always run them all with at least 900 wpc @ 4 ohms. They are all really great speakers if fed enough power.
Photos of my Kappa 9's can be seen at the website below.

I also used them in a home theater setup with two Kappa 7's in the rear and a Kappa center......no subwoofer was needed.
