Information
The JBL Control 31 utilizes high-power components, computer optimized horn, and a complex network to achieve smooth, powerful high-fidelity performance, extended bandwidth, and well-controlled defined coverage from a compact loudspeaker. The 250 mm (10 inch) low-frequency driver features a woven fiberglass cone for a high degree of weather capability and pure butyl rubber surround for clean sound quality, a high-temperature fiberglass voice coil former for high sensitivity, high output capability and stable performance under long-term high power working conditions. The optimized cone geometry provides for smooth frequency response and good off-axis performance. A linear suspension spider provides low distortion, while FEA-optimized motor construction produces minimum harmonic distortion. An aluminum coupler ring outside the pole post further reduces distortion and further increases the sensitivity. The high-output high frequency compression driver features a unique patented design, high temperature polymer diaphragm, and fluid-cooling for high output levels with low distortion.
The high-frequency waveguide was designed using JBL’s advanced ImageControl process for accurate, low-distortion control, with smooth frequency response and excellent sound character throughout the frequency band, over the entire listening area. It’s 110° x 110° symmetrical coverage, provides the same coverage regardless whether the cabinet is installed in vertical or horizontal orientation. The field-proven top-quality line distribution transformer, designed for minimal insertion loss and reduced saturation, allows for use on either 70V or 100V distributed speaker lines. In the Thru setting, the 8 ohm impedance allows for the use of up to two speakers on a 4-ohm capable amplifier channel.
The high-frequency compression driver has a highly weather capable polymer diaphragm. The grille is thermoset composite coated and stands up well to UV as well as humidity. The grille is backed with our WeatherMax multi-layer foam and tight-weave screening to help prevent 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. The white-version cabinets are painted with a UV-resistant finish to resist yellowing due to UV exposure.
