Mid-bass 15", 600W AES, 1200W Program |  |
|
|
|
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.
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 choice 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 a good solution for horn loaded or hybrid horn loaded systems. |
