Volt RV3863 Radial Bass Unit

 15" Paper Cone Bass

The RV3863 is a unique bass unit, featuring two cooling systems. In addition to the conventional rear vented magnet it uses Volt's patented  front mounted Radial chassis, which acts as a giant heatsink. This keeps the voice coil and magnet temperatures exceptionally low, resulting in superb reliability, 3dB less power compression and tight, clean bass even after prolonged use at maximum power.

The RV3863 has a symmetrical field magnet for absolute linearity and transient control on high power peak inputs and it's innovative design has produced a breakthrough in high performance and reliability.
