Infinity Kappa 9's sound terrible...HELP

Recently I got a pair of Kappa 8's. Plugged them into Adcom 860 preamp and to an old HK Citation 16, GFA-555 and GFA-565's. They sounded...beyond my wildest dreams! Absolutely amazing!

A week later I bought a pair of Kappa 9's. Was really excited thinking they would out preform the k-8's! Plugged them into the same system and they sounded like crap. Tried running each k-9 to 1 GFA-565 and bi-wire them, changed all knobs to flat, experimented with the adjustments on the back of the k-9's in every conceivable position, ran them in standard and extended bass modes...and they still sounded terrible!

Has anyone experienced this before? Any tests or checks I can do to eliminate any doubts of anything? If I can't resolve this on my own, I guess I'll have to take the speakers somewhere...if I can a reliable source between the Philadelphia to Harrisburg, PA area.

Also, if any can suggest any good techs between the Phila and Harrisburg area for amplifier rebuilds (Adcom GFA-555 II models) I would also appreciate getting a name and address.

Thanks guys...appreciate your help!

I always liked the 8's better. Friend of mine bought the 9's after hearing my 8's and gave up on them because he couldn't find an amp to drive them that he could afford or liked. Yours might be broken. They might make good organ donors for the 8's.

I never got around to doing the surgery on the xovers. There is an RS1b active xover listed now that might help tame the 9's one ohm impedance dip. Paradigm X-30's could work too. Ask an expert. All I know is that the top of the line Infinity/Genesis are active biamped.
