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 653.7i 6-3/4" speaker features a super-stiff woofer cone to minimize flexing that can cause distortion. The Plus One cone design offers a larger surface area than other 6-3/4" 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.
