Applications
The Control 30 utilizes high power compo- nents, computer optimized horn and coaxial component design, patent-pending cabinet manu- facturing 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 dis- tributed speaker lines. In bypass position, the
8ohm impedance allows use of multiple speak- ers 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 hori- zontal 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 for- mulation 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 ther- moset 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 con- nection. An MTC-PC2 sealed-entrance cover is included to further protect the speaker’s termi- nals.
JBL’s exclusive SonicGuard overload protection is virtually inaudible to the listener, ensuring reli- ability while providing full fidelity sound.
Available in black or white (-WH), the cabinet will accept a variety of paints to match any décor.
