## Description

The **Infinity 50. 9CS** 5. 25" two-way speakers feature 225 Watts of maximum power, a Plus One woven glass-fiber cone woofer, UHF dome tweeters, True Four Ohms compensation, an outboard crossover, and I-mount tweeter mounting kit including Startfish OEM adapter. The patent pending Plus One woofer cone technology provides more surface ares than other speakers of the same size, resulting in increased bass output and higher efficiency. The Edge-driven UHF dome tweeters deliver clear audio output to 35kHz, and are like tweeters found in high-end home audio speakers. They provide for better sonic integration with the mid-woofer, and they increase overall power handling. You can feel comfortable running the Infinity 50. 9CS speakers on any head unit because the impedance of Kappa speakers has been adjusted to a True Four Ohms, which compensates for impedance increases seen in some vehicles. The woven glass-fiber woofer cone material minimizes cone flex which provides low distortion and improved clarity. A computer-optimized voice-matched outboard passive crossover provides incredible performance, with superior detail and accuracy. And it features a user-adjustable tweeter level control. Experience the difference with the Infinity 50. 9CS 5. 25" 225 Watt two-way speakers!
