New LASE L10-750 10" Midbass Speaker. The LASE L10-750 is a professional mid-bass woofer featuring very high output and dynamics. Implementation of a 3" voice coil, copper wire winding has enabled considerable improvement in transient peak response and extension of mid-high frequencies. A specially designed M-roll surround guarantees low midrange distortion and perfect damping of spurious resonances. The LASE L10-750 is primarily designed to be horn loaded in medium and long throw systems. When mounted in compact size bass reflex enclosures, the combination of short voice coil, very low mass, and suspension control makes the LASE L10-750 a good choice for high power, 2-way satellite applications. Popular replacement for the RCF/EAW 804022 midrange driver found in EAW KF650 and KF850 loudspeaker systems.
