Sundown Audio SML12D4 SML-Series 12" 500W Shallow Mount Subwoofer 4 Ohm
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).

Real Installs. Real Sound.
See what enthusiasts are saying — straight from their builds
Low End You Can Feel
Bass Built for Daily Driving and Competition
Controlled Low End
Designed for tight, repeatable bass rather than one-note boom, so basslines and kick drums stay separate.
Built to Take Power
Voice coil, spider and cone materials are matched to the rated RMS so the sub handles sustained output.
Match the Enclosure
Performance depends on the box. Sealed for accuracy, ported for output. See the specs for recommended volume and tuning.
Wire It Right
Coil configuration decides your final impedance. Match it to a load your amplifier is stable at before wiring.
