Sundown Audio SML-12 D4 12” Shallow Mount Subwoofer – 600W RMS/1200W Peak Power, Dual 4 Ohm Voice Coils, 2.5" Black Aluminum Coil Former, High-Temp 4-Layer Copper Wire

Features

• SLIM YET POWERFUL: Despite its shallow depth, the SML-12 D4 delivers up to 600W RMS and 1200W peak output. Perfect for under-seat or trunk installations with space limitations, it maintains high excursion and delivers strong, deep bass without the bulk of traditional subwoofers.
• DUAL 4-OHM FLEXIBILITY: Designed with dual 4-ohm voice coils, this subwoofer offers flexible wiring options for maximizing amplifier compatibility. Whether youre wiring in series or parallel, the SML-12 D4 ensures optimal load matching and consistent power handling in your car audio system.
• HEAT-RESISTANT CONSTRUCTION: The 2.5 black aluminum voice coil former combined with high-temp 4-layer copper wire enhances thermal conductivity. This allows the subwoofer to maintain stable performance during continuous use at high volumes, reducing the risk of thermal breakdown.
• DURABLE ENGINEERING: With stitched-on Mini-XL tinsel leads and a bolt-through motor design, the SML-12 D4 is built to last. These features reduce the risk of fatigue or wire breakage under intense vibrations, making it a reliable choice for daily driving and powerful bass performance.

Description

The Sundown Audio SML-12 D4 is a 12” shallow mount subwoofer that delivers deep, clean bass in compact car audio systems. Engineered for limited-space installations, this powerful sub handles 600W RMS and 1200W peak while maintaining an ultra-slim design. It features dual 4-ohm voice coils for flexible wiring configurations, and a 2.5” black aluminum voice coil former for improved heat dissipation and performance reliability. High-temperature 4-layer copper voice coil wire ensures stability during high-output use. With a dual-magnet design, vented pole piece, and multi-vented magnetic gap, the SML-12 D4 provides a smooth acoustic response with reduced distortion and power compression. A custom-tooled cone minimizes mechanical noise at high excursion, delivering tight, controlled bass. Stitched-on Mini-XL tinsel leads prevent fatigue and failure, while the bolt-through motor design enhances long-term ruggedness. One inch shallower than the SLD series, the SML-12 D4 is perfect for under-seat or behind-seat installs in small sealed or ported enclosures—ideal for deep bass in tight spaces.Product Features:600W RMS / 1200W peak shallow subwooferDual 4-ohm voice coils for wiring options2.5" black aluminum coil formerHigh-temp 4-layer copper coil wireUltra-shallow mount fits tight spacesStitched Mini-XL tinsel leads resist fatigueBolt- through motor adds structural strengthDual-magnet motor for smooth bass outputCustom cone minimizes mechanical noiseIdeal for small sealed or ported enclosures
