Sundown Audio SML Series 8" D2 Ultra-Shallow Mount Subwoofer: Deep Bass for Tight Spaces.
The Sundown Audio SML Series 8" D2 Thin Subwoofer is a revolutionary solution for enthusiasts demanding powerful, accurate bass in extremely shallow mounting applications.
Engineered with Sundown Audio's renowned precision, the SML-8 D2 is an inch shallower than our SLD series, yet delivers astonishing excursion and deep low-frequency performance.
This subwoofer is the ultimate choice for custom installations under or behind seats, where conventional subwoofers simply won't fit.
Compact Power & Dual 2 Ohm Flexibility: The SML-8 D2 is a true powerhouse in a compact form, handling a robust 400 Watts RMS (800 Watts Peak).
This impressive power capacity ensures that even from a shallow-mount design, you experience impactful and dynamic bass.
With its Dual 2 Ohm voice coils, the SML-8 D2 offers excellent wiring flexibility.
Easily configure your system for a 1 Ohm or 4 Ohm final impedance (RE: 3.65 Ohms), ensuring optimal power transfer and compatibility with a wide range of car audio amplifiers, maximizing your system's potential.
Ultra-Shallow Design for Versatile Mounting: The defining feature of the SML-8 D2 is its incredibly shallow profile.
With a minimal 3.78” mounting depth, an 8.5” outer diameter, and a 7.65” cutout, this subwoofer is specifically designed to fit into the most challenging spaces.
Its ultra-compact dimensions make it ideal for installations where conventional woofers are too bulky, such as under-seat enclosures in trucks, behind seats in tight cabins, or custom panels with limited depth.
Despite its slim profile, it delivers surprising excursion, ensuring deep bass.
Advanced Thermal Management & Durable Construction: Reliability and longevity are paramount in the SML Series.
The SML-8 D2 features a 2.25” Black Aluminum voice coil former combined with high-temperature 4-layer copper voice coil wire for superior heat dissipation, crucial for sustained performance.
Further enhancing thermal efficiency are the vented pole-piece and vented magnetic gap, which promote constant airflow to cool the voice coil.
Stitched-on “Mini-XL” tinsel leads are implemented to prevent fatigue and failure under demanding conditions.
The robust bolt-through motor design ensures maximum longevity and ruggedness, providing peace of mind for years of powerful bass reproduction.
Optimized for Small Enclosures & Acoustic Purity: This subwoofer is meticulously designed to perform exceptionally well in very small sealed enclosures, making it incredibly versatile for space-constrained applications.
Recommended sealed enclosure volumes range from 0.2 to 0.35 cu ft, allowing for tight, accurate bass even in compact boxes.
Its custom tooled cone shape is engineered to reduce mechanical noise over its ample 14mm Xmax, ensuring clean and pure bass output.
The dual-magnet design further contributes to a smooth acoustic response, delivering high-fidelity sound.
With a Sens (dB @ 1w/1m) of 82.8dB, the SML-8 D2 makes efficient use of your amplifier's power.
Its FS of 40.038 Hz and Qts of 0.368 demonstrate its excellent characteristics for controlled, musical bass.
