Jbl CONTROL 31

The Control 31 speaker uses high-power components, an optimized horn, and a complex network of components to deliver uniform, high-fidelity sound, a wide frequency response, and well-defined coverage in a compact speaker. The 250-mm low-frequency driver (10'') features a woven fiberglass cone that provides high weather resistance and a butyl rubber surround for crystal-clear sound quality, along with a voice coil designed for high sensitivity, powerful output, and stable performance during continuous operation at maximum power. The optimized cone geometry provides uniform frequency response and good off-axis performance. The linear suspension system ensures low distortion, while the FEA-optimized design minimizes harmonic distortion. An external aluminum coupling ring at the mounting point further reduces distortion while increasing sensitivity. The high-frequency driver features a patented design with a high-temperature-resistant polymer diaphragm and fluid cooling to deliver high output levels without distortion. The high-frequency waveguide was designed using JBL's ImageControl to maintain consistent sound characteristics across the entire frequency band throughout the listening area. The symmetrical 110° x 110° coverage preserves these characteristics regardless of the speaker's horizontal or vertical orientation. The line-distribution transformer, designed for minimal losses and saturation, allows for use with 70V or 100V lines. In "Thru" mode, the 8-ohm impedance allows two speakers to be driven by a single 4-ohm amplifier channel. The InvisiBall mounting system simplifies any installation and provides theft protection, as well as off-axis rotation of up to 41° and vertical rotation of up to 36° or 23°. Mounting points for the optional MTC-30UB bracket (and the white "-WH" version) round out the installation options. All components offer maximum weather resistance. Available in black or white (-WH), the cabinet can be painted in various ways.
