Kapton forme voice coil, polycotton suspensions and treated cone guarantee the very high power handling of this transducer.

Features

• 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.
