L18S801

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.
Voice coil construction, suspension and cone materials are upgrade in order to withstand up to 700 watt RMS power.
