Product Details

Selenium 12MG1400 12" Woofer / Midbass Speaker

The Selenium 12MG1400 12" Woofer/Midbass Speaker is capable of producing high SPL midrange output when deployed in professional PA systems. Working equally well in both direct radiating and horn loaded enclosures, the 12MG1400's large ceramic ferrite motor and low mass 4" diameter aluminum voice coil contribute to the driver's high efficiency. A long fiber pulp cone and impregnated double half-roll fabric surround couple the motor to the air load, ensuring great dynamics and smooth response.

The 1,400 watt program power rating is achieved through the use of a polyimide voice coil former, high-temperature adhesives, and a large, tapered central vent in the pole piece. The entire assembly of moving parts is kept in perfect alignment by a cast aluminum and epoxy-coated frame.
