Features

• Extreme Power Handling: The Sundown Audio M12 subwoofer delivers immense bass with 2000W RMS / 4000W Peak power handling, ensuring phenomenal performance for even the most demanding car audio systems. This 12-inch subwoofer provides industry-leading levels of low-distortion output.
• Revolutionary Mega-Roll Surround: Featuring Sundowns custom-tooled Mega-Roll Surround and patented frame design, the M12 achieves an incredible 35mm one-way linear excursion. This allows for the lowest possible bass extension in small enclosures with minimal distortion.
• Advanced Thermal Management: Built for sustained high performance, the M12 includes a 3" diameter 4-Layer Round Wire Aluminum Voice Coil on a thick aluminum former. A high-velocity pole vent, heavily vented magnetic gap, and proprietary cast-aluminum frame-base venting system keep the coil temperature in check.
• Robust & Optimized Design: The M12 boasts a quad stacked 200mm (7.87) diameter motor structure with a 20mm thick top-plate for efficient magnetic circuitry. Its durable construction is highlighted by an etched all-black backplate and special M-series magnet boot design.
• Versatile Enclosure Compatibility: While optimized for 2.5 cu ft net ported enclosures (tuned to 32Hz with 40 sq in port area), the M-series uniquely excels in sealed (1.0 cu ft) and IB applications. This flexibility makes it a highly adaptable choice for diverse car audio systems.

Description

Sundown Audio M12 Car Subwoofer: The New Standard in High-Performance BassUnleash a new realm of low-frequency excellence with the Sundown Audio M12 Car Subwoofer. This 12-inch subwoofer redefines "entry-level" in the Mega series, delivering intense, high-fidelity bass with stellar low-frequency performance at industry-leading levels of low-distortion. Designed for professional car audio systems, the M12 combines groundbreaking engineering with a visually striking aesthetic, featuring a new laser-etched back-plate and special M-series magnet boot design, ensuring your setup not only sounds amazing but looks the part too.Extreme Power & Unmatched Excursion: The M12 is built to dominate, offering an impressive 2000 Watts RMS and 4000 Watts Peak power handling. This formidable power is harnessed by a custom-developed 3" diameter 4-Layer Round Wire Aluminum Voice Coil wound on a thick aluminum former, specifically designed for optimal winding packing density. This innovative coil drives an incredible 35mm one-way linear excursion, allowing for truly deep and impactful bass reproduction with exceptional clarity and minimal distortion, even at punishing volumes. Its RE (Ohms) of 4.0669 and robust BL (NA) of 23.84 contribute significantly to its formidable performance and control.Revolutionary Design & Patented Technology: At the heart of the M12's performance lies its custom-tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841) and our signature Mega-Roll Surround. This proprietary combination, coupled with Sundown's fully computer- optimized PG linear suspension, allows for the lowest possible bass extension while maintaining extremely low levels of distortion. The subwoofer's robust build is further enhanced by an etched all-black backplate and a massive quad stacked 200mm (7.87”) diameter motor structure with a 20mm thick top-plate, ensuring an incredibly efficient magnetic circuit.Superior Thermal Management for Longevity: To ensure sustained high performance even during the most demanding listening sessions, the M12 incorporates Sundown's highly efficient high-stroke coil ventilation system, originally developed for our flagship X and Z series. This advanced system features a high-velocity pole vent, a heavily vented magnetic gap through the back-plate, and our proprietary high- velocity cast-aluminum frame-base venting system. These meticulously engineered cooling mechanisms actively manage coil temperature, allowing the M12 to perform flawlessly and reliably for years to come.Optimized Enclosure Flexibility: The M-series was designed from the ground-up to become the new standard in the low-frequency / small, ported box subwoofer category for its price range. It is primarily optimized for 2.5 cu ft net ported enclosures with a recommended tuning of 32Hz and a generous port area of 40 sq in. Uniquely for a Mega series subwoofer, the M-series also opens up the possibility for sealed (1.0 cu ft) and IB (Infinite Baffle) applications, offering unparalleled versatility for diverse installation needs and acoustic goals. Its compact Outside Diameter of 12.67” and Mounting Depth of 10.88” provide flexible installation options for a wide range of vehicles.Industry- Leading Low Distortion: The M-series stands apart due to its incredibly linear suspension and the strategic inclusion of a magnet inner-diameter aluminum shorting ring. This critical component ensures superior inductive distortion performance across the entire frequency range, resulting in exceptionally clean, crisp, and highly accurate bass reproduction without unwanted artifacts. We are confident that the M-series will go down in car audio history as one of the best low-distortion subwoofers per-dollar of its time, delivering an unmatched audio experience.
