Product Details

RCF L15/554K 15" Woofer Speaker

Very high efficiency and good linearity are distinctive features of the RCF L15/554K midbass woofer. The L15/554K is designed to be mounted in compact sized bass reflex enclosures. A well-engineered combination of voice coil length, low moving mass, and superior suspension control makes the L15/554K an excellent choice for high power 2-way systems. Thanks to a very high BL/Re ratio, small mechanical depth, and a strong cone, this transducer is a good solution for horn-loaded or hybrid horn-loaded systems. Popular replacement woofer for the EAW BH500, BH215, and FR350 loudspeaker systems.
