JVC designed their Arsenal series to incorporate just about every single piece of technology they had to offer in a single sub. Advanced materials like the dual-layer Kevlar laminated hemp fiber cone makes for a tough and rigid surface, but also one that is lightweight. The 15″ subwoofer can be feed up to 1,500 watts RMS for monster low end response. A Rapid Fire Impedance Selector Terminal allows for you to switch instantly between 1-ohm or 4-ohm total impedance letting you wring out the best performance based on your amplifier. Helping to keep things cool is the Arsenal’s Thermal Transfer Technology built into the rugged chassis for rapid heat dissipation. Vents built into the die-cast aluminum basket and a bottom plate keep the interior of the sub cool even if things inside your car are getting a little hot.
