Product Overview
RCF's L15/554K is a high efficiency mid-bass woofer with good linearity. A Kapton formed voice coil, polycotton suspensions and treated cone guarantee the high power handling of this transducer.
Applications:
- The L15-554K is designed to be mounted in compact size bass reflex enclosures.
- The combination of voice coil length, low mass weight and suspensions control makes the L15-554K a good choice for high-powered 2-way systems.
- Thanks to a high BL/Re ratio, small mechanical depth and a strong cone, the L15-554K is good solution for horn loaded or hybrid horn loaded system.
