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

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.
As a current Kappa 8 owner everyone is giving you good advice. These speakers should not be used with Monster cable bi-wire. They just sound awful. However, they do work well with MIT cable, Slima cable and the old Tara Time and Space.

These speakers love tube power. They also like amps that can be driven into low impedance loads. The Odyssey monos sound good with them. The PS audio HCA-2 sounds good with them except beware the tweeeter can get hot if you play them loud ( think the amp is a little underpowered). Older Thresholds are also good. In my opinion most Japanese amps need not apply (except Stax). The Japanese amps are either too bright or can't drive the impedance. The Marantz Ma700 sound good with them.
I would also think the Innersound amp or a Classe would work well.

You might also try taming the wall behind the speaker with a Persian rug. Also stabilize the base. I use 50lbs. of sand on each speaker.
The owner's manual suggests raking them back at an angle
if they are too beamy. That's why the rear leg is adjustable. Getting a high powered amp is the best solution.
