Loaded. 4 Tower Speakers, two with forward lights, Perfect pass Cruise, Ipod/mp3 input, transom remote for stereo. Fiberglass platform. On the flip side. The X-15 is equal parts brash and bravado. Outfitted with the Zeroflex Flyer tower design with integrated board racks and under-floor ballast system, the X-15 offers up a unique style all its own to go with wakes that are in the true X-Series tradition — smooth transitions from flats to the tip of the wake.
