LoudSpeaker 250W High-impedance 100v Line 33 – 19 kHz

Description

The 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 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” for white) U-bracket allows for compact installation and is particularly useful for low-profile applications. Weather resistance has been maximized. The low-frequency driver features a woven fiberglass cone a pure butyl rubber surround and the basket is rear loaded into the baffle to minimize exposure. 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.
