RCF L15/554K
15" Replacement Woofer

OUR PART #  L15/554K


RCF's L15/554K is a high efficiency mid-bass woofer with good linearity.  A Kapton formed voice coil, polycotton suspensions and treated cone guarantee the high power handling of this transducer.

Features:

  • 4" 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 combination of voice coil length, low mass weight and suspensions control makes the L15-554K a good choice for high-powered 2-way systems.
  • Thanks to a high BL/Re ratio, small mechanical depth and a strong cone, the L15-554K is good solution for horn loaded or hybrid horn loaded system.
