PRV Audio left no boxes unchecked on the new 18SW3600 subwoofer. It features high power handling, 4.5″ inner and outer wound voice coil, fiberglass fiber former, powerful optimized ferrite motor, ribbed paper cone and waterproof cone treatment – all specially designed to provide powerful and accurate sub-bass frequencies with low distortion and low power compression.

Thanks to the optimized ferrite motor assembly of 30 mm, the 18SW3600 is lighter than a comparable ferrite driver at this power handling, making it perfect for mobile DJs and portable PA systems where the highest power handling is wanted with minimum weight.
A double silicon spider system ensures excellent control during large excursions of 54 mm peak-to-peak excursion before damage. A fully optimized T-pole design generates the minimum amount of flux modulation. The new dual forced cooling system guarantees a very efficient voice coil ventilation for minimum power compression and incredible power handling.
