Our take on the Sundown Audio SML-12-D2 12" 500W 2-Ohm Shallow Subwoofer

The Sundown Audio SML-12-D2 is a 12-inch shallow-mount subwoofer rated at 500 watts RMS with dual 2-ohm voice coils. Its 4.44-inch mounting depth lets it fit behind seats and in tight enclosures where standard-depth 12s won't go. The motor uses a double-stacked main magnet plus a secondary magnet, a bolted frame, shorting rings and gap venting, which is more motor hardware than most shallow subs at this power level carry. It suits people building a compact sealed or small ported box who still want real output, though shallow subs trade some low-end extension and excursion against full-depth drivers.

Best forTruck and SUV owners with limited mounting depthBehind-the-seat and under-seat buildsCompact sealed or small ported enclosuresBuyers wanting a 500W RMS shallow 12 with dual 2-ohm coils
Pros
  • Shallow 4.44-inch mounting depth
  • 500W RMS power handling
  • Dual 2-ohm voice coils for flexible final impedance
  • Double-stacked main magnet with secondary magnet
  • Bolted motor structure and gap vent cooling
  • 13mm one-way Xmax for a shallow design
Cons
  • Shallow design limits excursion and deep bass versus full-depth subs
  • Needs a well-built enclosure to hit rated power safely
  • Dual 2-ohm coils wire to 1 or 4 ohms, which limits amplifier matching
  • Heavier motor stack than many shallow rivals

About the Sundown Audio SML-12-D2 12" 500W 2-Ohm Shallow Subwoofer

The Sundown Audio SML-12-D2 is a 12-inch shallow-mount subwoofer rated at 500 watts RMS. It has dual 2-ohm voice coils and a mounting depth of 4.44 inches.

The motor uses a double-stacked main magnet and a single-stacked secondary magnet, with a full magnet ID, shorting rings and an optimized, vented magnetic gap for cooling. The motor structure is bolted to the frame to prevent motor shift. The frame is high-strength stamped steel.

Connections are made through spring-loaded terminals. The voice coils use flat tinsel leads.

Questions and answers

What amplifier power does the SML-12-D2 need?
It is rated at 500 watts RMS. Match it with an amp that delivers roughly that clean RMS at your final impedance, and set gains conservatively since shallow subs have less excursion headroom.
How do the dual 2-ohm coils wire up?
Two 2-ohm coils wire in parallel to 1 ohm or in series to 4 ohms. Pick the amp that makes its rated power at one of those loads.
Will it fit behind a truck seat?
Mounting depth is 4.44 inches, which is the key figure for tight spaces. Measure your available depth plus clearance for the frame and terminals before building the box.
Sealed or ported box?
Both work, but a sealed box is easier to fit in shallow spaces and is more forgiving. A small ported box can add output but needs careful tuning to stay within the sub's excursion limits.
How does it compare with a full-depth 12?
It gives up some excursion and low-end extension to fit shallow spaces. The motor hardware is strong for its class, but a full-depth sub of similar power will usually play deeper and louder.
What is in the box?
The subwoofer itself with spring-loaded terminals on the frame. Enclosure, wiring and amplifier are not included.
