Sundown Audio SML-12

We are a Sundown Audio authorized dealer so you get up-to-date, fully warrantied products.

The SML series is the shallowest line of subwoofers to ever be offered by Sundown Audio. Despite being over and inch shallower than our SLD series we are within 1mm of linear excursion comparatively. This is a huge win for customers requiring an extremely shallow driver. We found that the SML series will fit the majority of pre-fab under-seat enclosures and perform extremely well in the air-space provided by these enclosures as well. These will excel in such applications.

The biggest problem that we set out to solve while creating the SML was the fact that many shallow drivers, especially in this price range, have an incredibly high QTS making it very difficult to achieve a flat response and also making them quite unsuitable for ported enclosures (where the SML will also work well). After many months of work and testing prototypes we landed on the Dual-Magnet design motor and hit our mid-QTS target square on the head (0.34 to 0.51 range depending on size and coil configuration).

Performance:

• Xmax = 11mm one-way by 70% BL
• RMS Power = 500-watts

Key Features:

• Xmech is a hard limit of 25mm one-way for 12s and 20mm one-way for 10s
• Black Aluminum 2.5” voice coil former for superior heat dissipation
• High Temperature 4-Layer copper voice coil wire
• Stitched-On “Mini-XL” Tinsel Leads to prevent fatigue and failure
• Vented Pole-Piece and Multi-Vented Magnetic Gap
• Dual-Magnet Design for appropriate motor force factor and mid QTS
• Custom tooled cone shape for reduced mechanical noise over high excursion
• Bolt-through motor design to ensure maximum longevity and ruggedness against mechanical failures
  ** This motor is bolted through the top so the bolts are not visible from the back like several other models.
• Magnet ID shorting ring
