L15-554K
MID-BASS
Very high efficiency and good linearity are distinctive features of this mid-bass woofer.
Kapton forme voice coil, polycotton suspensions and treated cone guarantee the very high power handling of this transducer.
Applications
- • The L15-554K 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 L15-554K a very good choise for high power 2 way systems.
- • Thanks to a very high BL / Re ratio, small mechanical depth and a strong cone, the L15-554K is good solution for horn loaded or hibryd horn loaded system.
