Overview:

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.
