I recently purchased a pair of Kappa 8’s in very good condition. I don’t own an adequate amp to power them and only have been playing them gently using my 100w Yamaha receiver. I’ve read a lot on this forum about Kappa 8’s and what amps folks are using to drive their Infinities. I knew when I bought the Kappa 8’s that they require lots of power and just as important amps capable of handling the low dips in impedance that the Kappa 8’s present at different frequencies.
A review of the Kappa 8’s from the October 1987 issue of Stereo Review stated that “the impedance of these speakers was a nearly constant 2.4 to 2.8 ohms over the 1800 to 20,000 hz range and was one of the lowest speaker impedance they have measured.” YIKES!
I need some guidance as to what specifically should I be looking for in amplifier specifications to not make a mistake. If a manufacturer states that the minimum recommended speaker impedance is 4 ohms should that exclude the amp from consideration? Is it necessary that the manufacturer specifically state that the amp has the capacity to handle impedance dips down below 4 ohms?
So what do I look for to ensure an amp can handle these bad girls? I likely will want to bi-amp them.
