Driver Complement
The BH-500 is normally supplied, and functions
most effectively, with the EAW/RCF LF-384R driver
designed for it. Each EAW product is designed as an
integrated system, and the selection of driver parameters is
optimized for the intended system use. The EAW/RCF
LF-384R drivers, like all RCF professional drivers, are not
merely upgraded PA drivers but are engineered from the
frame upward to perform reliably at high power levels in
their respective applications. The LF-384R performance
record is excellent and when operated within its rated 300
watts RMS specification, field failure probability is
essentially zero.
The massive magnetic structure and large 100mm
(4") voice coil maintain low distortion and high efficiency
even under demanding continuous high power applications.
The design parameters are aligned for horn loading use
making this driver offer a higher efficiency than any other
commercially available driver able to reproduce low
distortion bass below 100 Hz.
