JBL Pro - Control 50 S/T White

The JBL Control 50S/T occupies a unique position within a subwoofer-satellite system: that of a bass unit placed against a wall in an entrance hall, foyer or conference room. Its capabilities include a continuous programme power rating of 300 W over 2 hours, coupled with a sustained output of 150 W of pink noise over the same period, and a long-term endurance rating of 200 W programme power over 100 hours or 100 W pink noise over 100 hours. The 600 W peak power handles peaks without flinching.

The 200 mm polypropylene cone driver features a 38 mm voice coil with four layers of copper-plated wire, mounted on a half-roll butyl rubber surround and a vented aluminium basket. This design delivers a frequency response of 32 Hz to 200 Hz (-10 dB), narrowed to 50–150 Hz within ±3 dB. Sensitivity reaches 95 dB at an angle and 89 dB at the centre of a wall, with a sound pressure level of 121 dB peak at an angle and 115 dB at the centre.

Two installation options are available thanks to the 8 Ω impedance in direct connection and the 70 V line transformer (80, 40, 20 or 10 W), a choice that covers both low-impedance coupling and a 2- or 4-satellite deployment on a 70 V/100 V line. Connectivity is provided via six lockable 2-pin connectors or a screw terminal block accepting cable up to 12 AWG.

The enclosure is constructed from structural plywood on the top, bottom and front, with MDF vent and terminal panels. A painted galvanised steel grille and 2.3 mm cold-rolled steel fittings protect the unit, available in white or black, providing omnidirectional coverage. The included wall bracket (depth 15 mm) comes complete with 4 M6 screws, a terminal cover, 6 connectors and an M6 screw for a safety sling. The speaker measures 391 x 356 x 203 mm and weighs 9 kg; the package weighs 10.2 kg.
