SKU: 18SW3600 Category: Tag:



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.

  • Tall 34 mm winding, 4.5″ voice coil handles 3600 watts Program RMS
  • Over 13.5 mm of Xmax for deep bass reproduction
  • High BL motor for impressive control and massive output
  • Dual 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 output

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.


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.

Quad - 18 PA subs

We just finished a new PA project. The owners of a local brewery wanted strong PA that would produce big sound when they wanted it for live music, but also provide well reinforced bottom end and lower levels. The 18SW3600's are performing flawlessly so far. The bottom end it tight and articulate and showing no signs of power compression when we push the rig. They are extremely low distortion to the point the owner of the brewery is amazed with the result. The best way I can describe them is effortless bottom end with excellent low frequency extension. Each woofer is in 4.8cuft net, tuned to 35Hz, which is working extremely well. The enclosures are a little smaller than the ideal simulated result, but the 18SW3600's don't seem to mind being in a little smaller air space (we were trying to hit a target form factor). I would highly recommend these woofers.

Love them

I have 2 of these in my suv running at about half power an there just insane. Hit 149 db. Very excited to get them up to full power
