Features
  • 4-inch, fiberglass inside/outside copper voice coil
  • 2000W continuous program power handling
  • 97 dB Sensitivity
  • 35 Hz – 1.5 kHz Frequency range
  • Forced air ventilation and 15mm top plate for minimum power compression
  • Dual spider design with silicone based dampening control
  • M-roll surround and exponential cone geometry

In production for over 20 years, the L18P300 is an industry-standard. With 15 mm thick plates and specially designed suspensions, the sturdy magnetic unit ensures an excellent amplitude control of over +/- 12 millimeters. The special cooling system with forced air ventilation offers excellent heat dissipation and minimum power compression. Voice coil construction, suspensions, and cone materials can withstand massive RMS power. The L18P300 finds its best application in bass reflex and bandpass systems. Its capacity to reproduce extremely low frequencies with remarkable definition makes it one of the favorite woofer in its category, ideal for live and recorded music.
