Kappa edge-driven silk dome tweeters equipped with oversized voice coils deliver silky smooth highs with impressive thermal power handling and 40kHz high resolution.
Infinitys glassfiber woofer cones are lighter and stiffer with more cone-area than the competition, delivering increased low-frequency output and higher efficiency. Hearing is believing.
The push-button on the angled tweeter allows tweeter output level control of 0dB or -3dB to optimize system linearity based on installation location.
