JBL Professional Control 19CS Subwoofer

The primary difference is that the Control 19CS is a direct 8-ohm model, whereas the 19CST variant includes a built-in transformer for use in 70V/100V distributed audio systems.

Yes, the Control 19CS is a passive subwoofer and does not have a built-in amplifier. You will need to pair it with an external power amplifier capable of driving an 8-ohm load.

The subwoofer provides a frequency range down to 42 Hz at the -10 dB point. It is designed to provide low-frequency reinforcement for full-range systems rather than extreme sub-bass output.

Yes, the steel back-can is an integral part of the enclosure design. It ensures the structural integrity of the unit and is essential for achieving the intended acoustic performance.

The unit is designed for in-ceiling mounting, but because of its steel construction, you must ensure your ceiling grid or structure can support the weight of the subwoofer. Always verify that your mounting hardware is rated for the specific weight of the unit.

The Nested Chamber design allows the subwoofer to produce deeper, more powerful bass frequencies from a relatively compact enclosure. It helps maintain a discreet aesthetic in your ceiling while still providing effective low-end reinforcement.
