Perfect compact bass reflex solution for live music.
Description
The L18S801 is the RCF classical high efficiency 18” woofer. A perfect blend of voice coil length, moving mass weight and suspensions control makes this transducer the preferred solution for many speakers and rental companies. Efficient heat dissipation is ensured by forcing air out through a special vented radiator system which is part of the gap, situated between the basket and the upper plate.
Voice coil construction, suspensions and cone materials are upgraded in order to withstand up to 700 Watt RMS power.

- 4-inch, fibreglass inside-outside copper voice coil
- 1400 Watt continuous program power handling
- 5 dB Sensitivity
- 38 Hz - 1 kHz Frequency range
- Forced air ventilation and front heat sink for minimum
- power compression
- Dual spider design with silicon based dampening control
- M-roll surround and exponential cone geometry
