INCLUDES: 1x 18SW3600 18" Professional Subwoofer - 3600 Watts FEATURES: PRV Audio left no boxes unchecked on the 18SW3600 subwoofer for serious professional audio applications where extremely high power handling and low distortion are required.HighlightsTall 34 mm winding, 4.5″ voice coil handles 3600 watts Program RMSOver 13.5 mm of Xmax for deep bass reproductionHigh BL motor for impressive control and massive outputDual forced cooling system. Under the spider and at its pole piece venting allows cooling the voice coil faster.Extremely high BL factor and Xmax for outstanding low frequency outputIt 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.The dual forced cooling system guarantees a very efficient voice coil ventilation for minimum power compression and incredible power handling.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.
