JBLControl 42C

2.5" Ultra-Compact, In-Ceiling Satellite Loudspeaker

2.5" Ultra-Compact, In-Ceiling Satellite Loudspeaker

            The Control 42C is an ultra-compact inceiling professional satellite loudspeaker designed for use with the Control 40CS/T subwoofer. When combined with the Control 40CS/T, the Control 42C offers an extremely natural sounding and powerful subwoofer-satellite system that is perfect for applications requiring wide bandwidth and superior sonic performance with minimal visual impact.

            The integrated backcan on the Control 42C combined with the C-ring support backing plate allows for a quick and easy installation of the unit. The system’s 60 mm (2.5 in) mid-high driver features a polypropylene cone and pure butyl-rubber surround for long life. The copper-clad aluminum voice coil wound on a vented aluminum former offers low distortion.

            The 16-ohm impedance allows paralleling up to 4 speakers on a 4-ohm capable amplifier.

            The Control 42C must be operated with either an active high-pass filter or a passive crossover, such as the one built into the Control 40CS/T subwoofer, to protect it against damage from low frequencies.

            Because of the very light weight of Control 42C, tile rails may not be required for many in-ceiling applications. They are not packaged with this model, however MTC-RAIL tile rail sets are available separately.

            Housed in a compact package, the lightweight Control 42C features an elegant, unobtrusive design and is ideal for both small and large projects alike.
