Volt RV4514 - 18" 1000W 8 Ohm

Read all about Volt Loudspeakers on the Blue Aran Blog :

Volt's Radial Chassis range uniquely 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 has a 4" (100mm) 4-layer copper voice coil, triple rear suspensions, double roll linen surround and a symmetrical field magnet for greater efficiency, linearity and motor strength.
