A true high-fidelity 4" x 6" coaxial speaker for your car. “High-end audio” is a phrase that too many people toss around lightly, but it genuinely applies to the the Infinity® Kappa® Series 462.11cfp 4-inch x 6-inch, two-way plate speaker system. The Infinity brand has a pedigree of technological innovation in reference-quality audio reproduction, and these speakers embody it. Each one features proprietary Injected Carbon Glass Matrix (iCGM) frames and patented formed-glass-fiber Plus One® woofer cones. The 3/4-inch (20-millimeter) tweeter is a soft-dome, edge-driven fabric diaphragm for improved power handling and wide high-frequency dispersion. Even the low-hysteresis polyproplyene capacitors and low-loss air-core inductors in the system’s passive filter networks are of ultrahigh quality. The system’s speakers, engineered to fit right into the 4-inch x 6-inch factory-made speaker locations common in many of today’s vehicles, deliver incredible attention to musical detail. The Infinity Kappa 462.11cfp is simply one of the best car audio speakers you can possibly buy, and we’re proud of it.
