JBL Control 19CST
JBL Control 19CST
In-Ceiling Subwoofer w/Multitap Transformer
The Control 19CST uses advanced proprietary technologies to produce powerful bass from a low profile in-ceiling design. The Control 19CST is perfectly suited to augment the low frequency output of any of the Control Contractor loudspeakers. High power handling and low distortion make the Control 19CST an ideal addition for sound systems requiring a higher fidelity sound from ceiling loudspeakers. The unique Nested Chamber design delivers high output from a compact enclosure, while the acoustic lowpass character of this design means it is easy to augment a full-range sound system without an external crossover or separate amp channel. The Linear Dynamics™ port design originally developed for JBL’s concert speaker systems, produces extended deep bass output. The premium performance capability ensures excellent sound character, providing pleasant, enveloping sound throughout the listening area. The 200 mm (8 in) transducer features a pure butyl rubber surround for extended life and long excursion capability. The pole piece is vented for low distortion. The Control 19CST can be connected into a system in a number of configurations: In parallel with full-range speakers resulting in a bass-overlap configuration (which is often acceptable); with an electronic crossover and separate amplifier channel, or; In conjunction with an active or passive high-pass filter on the full-range speakers, thus taking advantage of the Control 19CST’s natural acoustic lowpass character. The Control 19CST includes a high quality multitap transformer designed specifically for subwoofer use in either 70.7V or 100V distributed-line systems. Multiple transformer taps at 75W, 30W and 15W (plus 7.5W at 70.7V) allow the Control 19CST to fit a wide variety of listening situations. Taps are selected with a rotary switch conveniently located on the front panel, protected under the grille, so that the speaker does not have to be removed to adjust tap settings.
