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 degree off-axis and vertical rotation of up to 36 degree (horn end inward) or 23 degree (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. The cabinet will accept a variety of paints to match any decor.
