Infinity Kappa speakers incorporate the latest technology to provide you with outstanding sound reproduction. And, thanks to Infinity's innovative low-impedance design, they're built for high efficiency as well.
The Kappa 63.7i 6-1/2" speaker features a super-stiff woofer cone to minimize flexing that can cause distortion. The Plus One cone offers a larger surface area than other 6-1/2" speakers, for improved bass output and efficiency. The woofer's powerful, compact neodymium magnets weigh much less than traditional magnets a nice feature when you're trying to save weight in your high-performance vehicle.
Infinity incorporates an Emit ribbon tweeter for brilliant highs, and adds an M.M.D. midrange to reproduce the vocals in your music just the way they were recorded, with minimal coloration or distortion.
The computer-optimized outboard crossover employs audiophile-grade components to separate highs and lows so that the woofer and tweeters work together perfectly. A tweeter level control allows you to tailor the tweeters' response for perfect balance.
Important Note: These Infinity speakers use a low impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with all factory and aftermarket stereos.
