Product Details

RCF L12L750 12" Midbass Speaker

Very high efficiency and extended linearity are special features of RCF's L12L750 midbass transducer. Efficient heat dissipation is ensured by a radiator that is part of the basket design. The aluminum voice coil provides a properly aligned Q factor and high sensitivity. A specially designed shallow triple-roll surround guarantees low midrange distortion, and a fiberglass former voice coil, polycotton suspensions, and treated cone contribute to the L12L750's very high power handling. When mounted in compact size bass reflex enclosures, the good combination of short voice coil, very low mass, and suspension control makes the L12L750 an excellent choice for high power, 2-way satellite applications.
