JBLControl 40CS/T

8", In-Ceiling Subwoofer with Crossover

8", In-Ceiling Subwoofer with Crossover

            Control 40CS/T is a direct radiating, high impact, 8" subwoofer designed to produce powerful bass performance in an in-ceiling loudspeaker. Featuring high power handling and low distortion, the Control 40CS/T subwoofer is perfect for in-ceiling sound systems requiring higher fidelity and low end extension.

            The Control 40CS/T also features a builtin passive crossover network enabling the Control 40CS/T to be used as part of a subwoofer-satellite system. When combined with the Control 42C, the Control 40CS/T offers an extremely natural sounding and powerful subwoofer-satellite system that is perfect for applications requiring wide bandwidth and superior sonic performance.

            Featuring a large backcan along with a high powered driver, the Control 40CS/T provides extended bass response for a warm full-bodied tone. The system’s 200 mm (8 in) woofer features a polypropylene cone and pure butyl-rubber surround for long life. The copper-clad aluminum voice coil wound on a vented aluminum former provides low distortion and high sensitivity.

            Ideal for small and large projects alike, the Control 40CS/T is switchable for use as either an 8-ohm low-impedance speaker, or as part of a 70V/100V distributed loudspeaker system.
