The Control 40CS/T is a direct radiating, high impact, 8" subwoofer with a built-in passive crossover network enabling the Control 40CS/T to be used as part of a subwoofer-satellite system.
The Control 45C/T is a premium in-ceiling professional loudspeaker designed for applications that can benefit from extremely wide bandwidth and very consistent coverage from a ceiling speaker with a small footprint.
Built on the same platform as the Control 47C/T, the Control 47CT LP is a low-profile model intended for locations with limited above-ceiling clearance (only 5.6 inches deep)
