Features
  • 3-inch, fiberglass inside/outside copper voice coil
  • 1000W continuous program power handling
  • 98 dB Sensitivity
  • 40 Hz – 2 kHz Frequency range
  • Dual spider design with silicon based dampening control
  • M-roll surround and exponential cone geometry

High power 15" woofer. Very good power handling, excellent linearity and very low distortion. Very efficient heat dissipation in ensured by a radiator that is part of the basket design. The air is forced in the radiator thanks to a dual sealed spider design.
