Notice On Packaging For Subwoofers
Sundown Audio has led the industry in quality and performance for over a decade. To improve accuracy and transparency, we have updated our subwoofer power ratings to reflect true real-world performance.
During this transition, some packaging may show previous ratings. Performance fully aligns with our current published specifications. If you have any questions about authenticity or ratings, please contact directly for confirmation.

Impedance: D4
  • 1250 Watts RMS / 2500 Watts Peak
  • Dual 2 or 4 ohm voice coils
  • Vented magnetic gap & pole piece
  • Aluminum 2.75” voice coil former for superior heat dissipation
  • Magnet ID faraday ring for smooth acoustic response
  • High-temperature copper voice coil wire
  • Spring-loaded terminals
This SA-10/12/15 v.2 series is a top-down upgrade from the original SA series. The 2.75” coil punches way above its weight, outperforming many 3” coils without the adding weight & with the added advantage of a wider spider. We are able to perfectly balance the mass, motor force, and suspension stiffness for the intended power level.

The motor also features a large magnet shorting ring (faraday ring) to reduce distortion and deliver smoother response across the entire acoustic spectrum. The motor & coil setup is mated to an extremely robust multi-layer spider with fully tied-on & doubled-up “XL” tinsel leads. A competition-grade paper cone, strong foam surround, and cast aluminum frame are used to complete this masterpiece. On top of the ~19mm of one-way linear excursion we have an x-mech limit of 37mm one-way before coil bottom making it nearly "bottomless."

The 18" model features a larger diameter motor to drive the higher mass.
