JBL's Control 52 satellite loudspeaker produces superb high fidelity sound via a low distortion 60 mm (2.5") driver, which features a secondary bucking magnet for high efficiency, rubber half roll surround for enhanced bass performance, 19 mm (0.75") copper clad aluminum wire voice coil on a vented Nomex® former for high fidelity and reliability, and a copper-capped pole piece for more consistent impedance and extended high frequency response. The wall bracket allows each speaker to be angled up to 45° off-axis.
