You're damn right. I paid $230 cdn for my Kappa 15's.How on earth did you get that price? His site says like $200 for the Kappa's. I'd be careful if I were you.
The Kappas are my favourite of the Eminence drivers. I think they have the best price to performance ratio from my experience. Only bad thing about them really is peaking in the 2 kHz region. Impedance compensation will help get rid of the nasal midrange sound.
I have most experience with the Kappa 15LFA's.
