Infinity Kappa 9's Tweaks?

I have a pair of Kappa 7's and have had for years. I always ahd the issue of the "screaming at me" and although the emits are accurite and quick they can as you say fatigue you. First off Kappas love power. I started out with a Yamaha M85 Amp with 350 (yamaha watts) and they were ok, then I went to a Mcintosh 5 channel amp with 200 watts. They sounded cleaner but still screamed. So I bought a McIntosh MC352 with 350 (mcintosh watts) and WOW
the tweeter tamed down without losing thier accuracy, the sound stage really opened up and the imaging has been great. I wish I could afford a MC602 because I really beleive that the speakers would come to fruition of the designers intent. I don't know what your drving them with but my recommendation is POWER to the SPEAKERS. Or use the amp money and go buy some more efficent speakers, which is what i am trying to do.

Thanks Theo, I am also using a large yamaha pc2602m amplifier. Some one has shown intersest in the Kappas and I was thinking of going to the other end of the chain and trying a set amp with single drivers. In the interum I have a pair of RS3'S that do well with a lesser amp.

The Kappa's have a couple of below 1 ohm dips in there responce, you will need an amp that can deal with this to get them to sound their best. Any amp under constant strain will cause listener fatigue and no amount of tweeter padding will help this. Get an amp that is stable with this tuff to handle load and most of the emits brightness will go away, you can then deal with the tweets on their own with little problem. A toe-out of your speakers may help, along with a few other small tweeks. The Infinity emits get more than their fair share of blame for the brightness of the Kappa line.

i have owned the 8's and 9's you need the big powerful amps to push them! they are awesome speakers when powered right.
