  • Features:
    The RV3813 is a unique loudspeaker that uses Radial Technology to allow exceptional power handling and reliability. It is ideally suited for use in two way systems with a horn and compression driver or as a stand alone driver in a bass guitar system.
  • Benefits:
    The RV3813 features three cooling systems. In addition to the usual vented magnet it uses the patented Radial chassis, which acts as a giant heatsink, plus a multi-finned magnet intercooler. This keeps voice coil temperatures exceptionally low resulting in 3dB less power compression and tight, clean bass after prolonged operation at maximum power. It has a symmetrical field magnet and performance equivalent to a unit with a 100 mm voice coil.
