The uniquely designed RV4514 uses Radial Technology and is optimised for horn loaded bass systems

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").
