The unique and flexible AS-IC6st technically is two speakers in one! It houses a 6-1/2” woofer with dual voice coils, and two ¾” Teteron tweeters. There are dual input terminals on the speaker, so you can wire both left and right audio signals to the single speaker location, and have stereo sound. In a distributed audio application, this cuts in half the number of speakers needed, drastically reducing the overall cost of the system.
