The JBL Control 19CS is a high-performance in-ceiling subwoofer designed to enhance the low-frequency output of ceiling speaker systems, delivering powerful bass while maintaining a low-profile appearance. This subwoofer is engineered to complement JBL’s Control Contractor loudspeakers, making it an ideal choice for applications that demand robust bass response without compromising on sound quality or aesthetics.

Featuring JBL’s advanced proprietary technologies, the Control 19CS excels in producing deep, impactful bass from a compact enclosure. Its design integrates a unique Nested Chamber, a feature that allows for high output in a confined space. This innovative design not only maximizes the acoustic performance but also simplifies system integration by eliminating the need for an external crossover or separate amplifier channel. The result is an efficient and seamless addition to any full-range sound system, enhancing overall audio fidelity and depth.

One of the standout features of the Control 19CS is its Linear Dynamics™ port design, a technology initially developed for JBL’s renowned concert speaker systems. This port design is engineered to extend the deep bass output of the subwoofer, ensuring that low-frequency sounds are reproduced with clarity and impact. The port’s design contributes to the subwoofer’s ability to produce extended bass frequencies without introducing distortion, making it a valuable asset for high-fidelity sound systems.

To safeguard against overload damage and ensure reliable operation, the Control 19CS incorporates JBL’s exclusive SonicGuard™ circuitry. This protection system is designed to be inaudible to the listener, preserving the integrity of the audio signal while providing robust protection for the subwoofer. This feature is essential for maintaining consistent performance and longevity in various audio environments.

The Control 19CS is equipped with a 200 mm (8 in) transducer, which includes a pure butyl rubber surround for extended durability and long excursion capability. The pole piece of the transducer is vented to reduce distortion, contributing to the overall clarity and accuracy of the low-frequency output. This design ensures that the subwoofer can handle high power levels while delivering deep, resonant bass that enhances the listening experience.

Installation flexibility is a key advantage of the Control 19CS. It can be integrated into a sound system in several configurations to suit different needs and preferences. It can be connected in parallel with full-range speakers, resulting in a bass-overlap configuration that can effectively enhance low-frequency performance. Alternatively, it can be used with an electronic crossover and separate amplifier channel for precise control over the bass output. Another option is to pair the Control 19CS with an active or passive high-pass filter on the full-range speakers, taking advantage of the subwoofer’s natural acoustic low-pass character to achieve optimal sound balance.

In summary, the JBL Control 19CS subwoofer offers exceptional performance and versatility for a wide range of audio applications. Its advanced design, high power handling, and flexible installation options make it a valuable addition to any ceiling speaker system, delivering powerful, high-fidelity bass that enhances the overall audio experience.
