JBL Control 31-WH 10" SpeakerJBL1661
The Control 31 utilises high-power components, computer optimised 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 fibreglass voice coil former for high sensitivity, high output capability and stable performance under long-term high power working conditions.
The optimised cone geometry provides for smooth frequency response and good off-axis performance. A linear suspension spider provides low distortion, while FEA-optimised motor construction produces minimum harmonic distortion. An aluminium coupler ring outside the pole post further reduces distortion and further increases the sensitivity.
