L18P200-N
WOOFER
The L18P200-N is teh RCF classical extended low Frequency 18" woofer.
Generous voice coil length, heavier moving mass weight and very low resonance for perfect low frequency reproduction.
Remarkable the linearity in the application range.
Special treatments are applied to cone surface and surround for optimum dampening.
Applications
- • The L18P200-N finds its best application in bass reflex enclosures.
- • It is a perfect solution for recorded music, cinema subwoofers, very low frequency monitoring and applications where very low frequency linearity is required.
