Infinity Kappa 9

, , ,

Very well looked after and great example of this highly regarded speaker. 5 way design comprising SEMIT Super tweeter and tweeter. Require high power & current amplifier but once tamed these speakers are compelling and highly rewarding.

In keeping with Infinity’s relentless innovation, they introduced new midrange drivers – the Polygraph and Polydome. The Kappa 9 was a five way speaker, with a reputation for killing amplifiers – its impedance curve drops below 1 Ohm at two different places. Not very forgiving of weak amplifiers. Nevertheless, it has a dedicated following of devoted fans, who love the outstanding bass from them. Subsequently, Infinity produced later generation Kappas (the X.1 and X.2) series that were supposed to tame the Kappas appetite for amps.
