  • Features:
    The uniquely designed RV4514 uses Radial Technology and is optimised for horn loaded bass systems
  • Benefits:
    The RV4514 features three cooling systems. In addition to the usual vented magnet it also 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. The RV4514 also has a 4" (100mm) 4 layer voice coil, double rear suspensions, double roll linen surround and a symmetrical field magnet for greater efficiency, linearity and lower moving mass than alternative conventional loudspeakers. The result is a loudspeaker with Thiele-Small parameters optimised for use with horn systems enabling high SPL and low bass extension. Maximum damage limited cone excursion is 50 mm (2").
