Infinity Kappa 8's

Thanks for all of the helpful comments out there. The Yamaha P2200 has driven Apoggee Caliburs and Mb Quart 980's, both of these speakers dip into the low,low impedance area, and the amp never popped a fuse or shut down. Remember this is not a consumer amp, but an amplifier that has proven it's reliablity over the years in many studios. Upon further investigation I noticed a very well concealed setting for the woofers under a plastic cap located outside the speaker binding & controls plate. The factory setting is extended range. Infinity suggests throwing the switch into the normal position (which it already was in) to reduce the current requirements to the woofers. Next step suggested I'll take, is testing for a short with an ohm meter. These are the other amps I have available to drive the Kappa's. Yamaha M80 & M85 (both 200 watt range)and a friend has a Sumo polaris.Sorry but a Krell, Levinsen and Classe at the power required is just outside of my budget.

There are a few Classe 200/201's listed around the $1200 range. IMHO that's reasonably short $$$ to get the job done right. The Yammie is a good amp, however it just ain't got enough when the impedance dips. That P2200 is about to celebrate it's 30th birthday, maybe it's time to put the old girl out to pasture ;-)

Good luck,

look for a pair of B&K M200 Sonatas. They're stable to 1 ohm, capable of 150 amps peak-peak, and sound wonderful. They can be found for <$600, and on occasion <$500.

As someone else pointed out, the 8 kappa can be driven with even an Adcom 545. I own these speakers and have driven them with (without a single "incident") SAE A202, Adcom 545 Mk II, Aragon 4004 Mk II, Hafler 9500, Odyssey Audio Stratos. They are not impossibly difficult to drive. You must either be driving the amplifier hard (into clipping) or there's a short in your crossover.

A pair of Carver Silver 9t monoblocs for about $1200 will drive them with complete authority and make them sing. 900 wpc @ 4 ohms. I use them to drive the amp-killing Kappa 9's.
