Radial chassis technology
exceptional power handling and superb reliability
The uniquely designed RV3143 uses Radial Technology to allow exceptional power handling and reliability. The RV3143 features three cooling systems:- in addition to a vented magnet it uses the Radial chassis, which acts as a giant heatsink, plus a multi-finned magnet intercooler. This keeps voice coil and magnet temperatures exceptionally low resulting in superb reliability, 3dB less power compression and tight, clean bass even after prolonged operation at maximum power. The RV3143 has a symmetrical field magnet with extended centre pole for absolute linearity and transient control on high power peak inputs. It has double rear suspensions for stability and a 4 layer voice coil to maximise BL.
