  • Features:
    High power handling with low power compression for maximum dynamic range and accurate bass with Radial reliability
  • Benefits:
    The RV4564 bass unit is optimised for accurate bass reproduction. It has a massive Xmax, a symmetrical field magnet and extended centre pole for linear excursions up to 25mm peak to peak with accuracy and control. The critically doped carbon fibre loaded cone maintains rigidity for transient punch and slam. It features three cooling systems: a vented magnet, the patented Radial chassis and a multi-finned magnet intercooler. This technology keeps voice coil temperatures exceptionally low and substantially reduces power compression to maintain the full dynamic range even after prolonged operation. Additionally the stability of the Thiele-Small parameters resulting from cooler operation preserves system bass performance at high levels. The RV4564 is intended for use in high power professional studio monitors and sub bass systems.
