4-inch, fiberglass inside/outside copper voice coil
1200W continuous program power handling
99 dB Sensitivity
40 Hz – 2 kHz Frequency range
M-roll damped surround
Exponential damped cone
Copper ring
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.
