The JBL's C60PST pendant subwoofer provides bass extension and high impact for high-fidelity sound systems. The long-excursion 200 mm (8 in) low frequency driver has a butyl rubber surround for well-damped, tight sound quality and long-term durability, as well as a polypropylene-coated cone for humidity protection and 150 Watt power handling. This public address system has low-mass fibreglass coil former and high-temperature 50 mm (2 in) voice coil that offer good bass transient response and great stability under high power, high dutycycle working circumstances.
