• HEX stands for High Excursion. These woofers come in 2500W and 5000W RMS models in 12-, 15- and 18-inch versions with enormous 220mm, 250mm and 280mm diameter magnets that deliver floor-shaking bass.
• 3- and 4-inch voice coils with a winding height of 75 mm allow the woofer to maintain full electrical control while moving on its 2-way linear motion of 70 mm. Large excursion and xmax means that the woofer moves huge amounts of air, delivering incredible bass and enormous air pressure.
