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 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.
