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.
Infinity Kappa 9's Tweaks?
Calling all classic Infinity Fans. I have a set of Kappa 9s and they are a bit much for my modest listening room. They are so dynamic that they tend to fatigue, and moving away from them helps but room restraints prevents this. Also sound batting is not an estetic option. Does anyone no of a tweak with covering part of the tweaters with felt? This was mentioned on audio reveiew and I am not willing to permanently change them with crossover or wiring mods (they are getting to hard to find stock). Also I have tryed EQ's but always seem to go back to my foreplay tube preamp only.Thank you for any help. Audiogon is a great site. Guycom
