Alpine uses a powerful magnet and a super-efficient motor structure to make the 6-1/2″ woofer really strong in the lower frequencies. The woofer cone itself uses a specialized fiber for extreme rigidity while Alpine’s proprietary High Amplitude Multi-Roll surround ensures durability in the face of extreme temperatures

The separate 1″ carbon graphite dome tweeter handles the high frequencies with satisfying accuracy, and its extended frequency response lends a sense of realism and atmosphere unmatched by lesser tweeters. Driven by an aftermarket amplifier, you’ll really have a soaring system, thanks to power handling up to a whopping 120 watts RMS.
