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.
Available in black or white (-WH), the cabinet will accept a variety of paints to match any décor.
