The special cooling system with forced air ventilation offer a great haet dissipation and the minimum levels of power compression available on the market.
Voice coil construction, suapensions and cone materials are upgraded in order to withstand up to a Kilowatt RMS power.

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 silicon based dampening control
• M-roll surround and exponential cone geometry

Applications

• The L18P300 finds its best application in both bass reflex and band pass system.
• Its capacity to reproduce extremely low frequency along with extraordinary definition make it a no compromise woofer in its category, ideal for both live and recorded music.
