The Control 18S is designed to augment
the low frequency output of any of the
Control Contractor loudspeakers, and is ideal
for foreground music and music/paging
systems in a wide variety of applications such
as restaurants, retail establishments, theme
bars, music cafes, outdoor theme and water
parks and health clubs.
Sharing the same cabinet enclosure
dimensions as the Control 28, the Control 18S
is an excellent visual and acoustic match with
the Control Contractor surface-mount
speakers.
The unique globally-patented InvisiBall
TM
mounting hardware is included in each
system and makes short work of permanent
installation. The InvisiBall mounting method
has the additional benefit of allowing vertical
rotation of up to 37° off-axis and horizontal
rotation of up to 44° off-axis. Because
InvisiBall adjustments are made through a
hidden access behind the logo badge, the
grille never needs to be removed and there
exists a high degree of theft deterrence.
The Control 18S is available in black
(Control 18S) and white (Control 18S-WH)
and the cabinet accepts a variety of paints
and finishes to match any decor.
The Control 18S is protected from overload
damage by JBL’s exclusive SonicGuard
TM
circuitry, a protection system that is inaudible
to the listener, ensuring reliability while
providing full fidelity sound. The premium
performance capability ensures excellent
sound character, providing pleasant,
enveloping sound throughout the listening
area.

Continuous Pink Noise rating is IEC-shaped pink noise with a 6 dB crest factor for 100 hours continuously.
Continuous Program power is a conservative expression of the system’s ability to handle normal speech and music
program material and is defined as 3 dB above the Continuous Pink Noise Rating.

Average 60 Hz to 100 Hz.
JBL continually engages in research related to product improvement. Changes introduced into existing products

䉴 Control®18S/ST Indoor/Outdoor Subwoofer
The Control 18S 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; Running a
full-range signal into the Control 18S and looping through the highpassed satellite output to full-range speaker(s).
The optional Control 18ST version (and Control 18ST-WH in
white) includes a high quality multitap transformer designed
specifically for subwoofer use in either 70.7V or 100V distributedline systems. Multiple transformer taps at 60W, 30W and 15W (plus
7.5W at 70.7V) allow the Control 18ST to fit a wide variety of
listening situations. Taps are selected with a rotary switch
conveniently located on the back of the cabinet. The transformer
effectively limits the power to the speaker, so SonicGuard is not
included in the Control 18ST
Frequency response (1W, 1 m) is measured on-axis with two
boundary junction ( loading, gray line) and with three boundary
junction (/2 loading, black line)
