The JBL's C50PACK is a professional quality public address system that includes four Control 52 loudspeakers and a Control 50S/T subwoofer.
Each speaker includes a 2.5-inch diameter "driver with a rubber half roll surround for improved bass performance and an efficient magnet construction. The voice coil is copper-clad aluminium wire on a vented Nomex former for great fidelity and reliability, while the copper-capped pole piece provides stable impedance and extended HF response. The speaker is versatile enough to function with 70/100V distribution lines and low-impedance systems, and the accompanying wall mounting bracket allows you to position the speaker up to 45 degrees off-axis.
A thin, discreet cabinet houses an 8" long-excursion driver with a high-mass cone and a 4-layer copper voice coil for extended low-frequency response and strong motor strength. The metal former has a good transient response, and the rubber half roll surround improves bass performance. The subwoofer has a continuous power handling capability of 150W. It offers a low-impedance operation and a configurable 70/100V output for distributed lines. Depending on your needs, the subwoofer can be linked with two or four satellite speakers. The subwoofer comes with mounting brackets for mounting it to the wall.
