Very high efficiency and good linearity are distinctive features of this mid-bass woofer.Kapton former voice coil, polycotton suspensions and treated cone guarantee the very high power handling of this transducer. The L15/554 is designed to be mounted in compact size bass reflex enclosures. The good combination of voice coil length, very low mass weight and suspensions control makes the L15/554 a very good choice for high power 2 way systems. Thanks to a very high BL/Re ratio, small mechanical depth and a strong cone, the L15/554 is a good solution for horn loaded or hybrid horn loaded systems.
