Infinity Kappa 8's


What to do? My infinity Kappa 8's keeps eating amps for lunch.The 1st failure was with a Yamaha 200 watt per channel model P2200. Amp went black, I replaced the main fuses on the back of amp, it powered-up with new same rating fuses and then amp died again for good.Tryed another P2200 fuse blew again. I've decided not to try the amp again, for fear of completely damaging my last P2200. This is getting expensive! I'm not cranking the volume at full tilt or pushing the bass tone control past 12 o'clock. The speaker can be Bi-amped, but I've just used a single robust P2200 on them. The speaker wire uses large 1/4 inch bananna connectors, so no bare wires can not touch positive to ground on the back of the amp or speakers and the 4 binding posts on the speakers flat metal plates to connect the two binding posts together for single amp operation. Could a faulty cross-over wreak this havoc upon me. Any helpful suggestions will be greatly appreciated.

Got a set in my HT system behind a Sunfire. Sound better bi-wired than they did with two Adcom 555's - though neither setup ever gave me any trouble. My bud just bought a pair of 565's for $900 about a month ago. Good luck!

So what's a good bi-amp setup under ~$2000 for these speakers? I see the 565's going for $900 as described. Are those good for the low's? What's good for the highs?

Thanks!

The Odyssey Stratos amps are a perfect sonic match for the Kappa speakers and will supply plenty of current. And at a price that won't break the bank. Peace of mind with the 20 year warranty. I use 4 Odyssey Monoblocks for my Kappa 9's and a Odyssey HT-3 for my Kappa center and Kappa 8 rear surrounds. Sounds fantastic.

As a long time Kappa 8 owner I can strongly recommend a simple bypass modification to the crossover that makes the speaker easy to drive and actually better with a more natural and full bass response. Simply unsolder or cut one side of the 12.5 mh coil from the crossover and solder in a shorting bridge across any one of the three 500uf (1500uf total) capacitors that are the first thing after the woofer binding posts. This takes the 'reactor' out of the woofer circuit. Now your amp will just see a common 4 ohm load and the bass will be very natural without the 'thump' where that cap and coil reactor stores a charge and throws it at the woofer while melting your amp in the process. I listened carefully using the famous Hok-Man Yim Poem of Chinese drum CD and it actually hits harder with better decay after the mod and the amp doesn't overheat in the slightest. The Kappa 8's punch that track harder than anything I have owned with just one 12 per side. If you want to keep protection against a DC short from your amp, ignore shorting out the (series) capacitor, but by all means get that evil 12.5 mh (shunt) coil out of the woofer circuit.
