Applications
The Control 30 utilizes high power components, computer optimized horn and coaxial
component design, patent-pending cabinet manufacturing techniques, and a complex network to
achieve smooth high fidelity performance,
extended bandwidth and well-controlled, defined
coverage from a compact loudspeaker.
A symmetrical mid-high frequency horn allows
use of the speaker in either vertical or horizontal
orientation. Smooth frequency response and
cone-midrange performance ensures excellent
sound character throughout the frequency band,
over the entire listening area.
The top-quality line distribution transformer,
designed for minimal insertion loss and reduced
saturation, allows use of either 70V or 100V distributed speaker lines. In bypass position, the
8 ohm impedance allows use of multiple speakers on a loudspeaker line.
The included InvisiBall mounting method is
simple to install, aims easily and provides a high
degree of theft deterrence. InvisiBall allows horizontal rotation of up to 41° off-axis and vertical
rotation of up to 36° (horn end inward) or 23°
(woofer end inward). Attachment points for the
optional MTC-30UB (-WH) U-bracket allows for
compact installation and is particularly useful for
low profile underbalcony applications.
Weather resistance has been maximized. The
neodymium magnet LF woofer has a fiberglass
and Kevlar composite cone, the surround is pure
butyl rubber, and the basket is rear loaded to
minimize exposure. The MR cone of the coaxial
mid-high driver is anodized aluminum with a formulation EPDM rubber surround, and the HF
compression driver’s diaphragm is pure titanium.
The coaxial component is protected by an
acoustically transparent screen. The grille is thermoset composite coated and stands up very well
to UV as well as humidity. The grille is backed
with our WeatherMax multi-layer foam, which
prevents the direct incursion of water. Nickel/zinc
rust-resistant terminals ensure a secure input connection. An MTC-PC2 sealed-entrance cover is
included to further protect the speaker’s terminals.
JBL’s exclusive SonicGuard overload protection
is virtually inaudible to the listener, ensuring reliability while providing full fidelity sound.
Available in black or white (-WH), the cabinet
will accept a variety of paints to match any
décor.

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

Usable frequency response shall extend from 38 Hz to 17 kHz (10 dB
below rated sensitivity, half-space, no external equalization). Rated
power shall be at least 500 watts continuous program power for 100
continuous hours duration (defined as 3 dB above a test signal of filtered random pink noise conforming to IEC268-5). Measured sensitivity
shall be at least 93 dB-SPL (at 1m [3.3 ft] with 2.83V input, avg. 100 Hz

High-Pass Frequency Recommendations
The line-matching transformer in the Control 30 has
been designed to minimize saturation; however, it is recommended that the system be high-passed to prevent
very low-frequency content from overloading the transformer and/or the driving amplifier at high signal levels.
The high-pass requirements vary according to the tap
settings and number of speakers connected in parallel.
The following chart will eliminate risk of saturation,
even at full voltage (70V or 100V) peaks. Reducing the
drive voltage will enable a corresponding reduction of
high-pass frequency (24 dB/octave high-pass slope).
