## Description

Sundown Audio M15 Car Subwoofer: The New Standard in High-Performance BassUnleash a new realm of low-frequency excellence with the Sundown Audio M15 Car Subwoofer. This 15-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 M15 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 M15 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 2.1 and robust BL (NA) of 17.006 contribute significantly to its formidable performance and control.Revolutionary Design & Patented Technology: At the heart of the M15'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 M15 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.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 4.25 cu ft net ported enclosures with a recommended tuning of 32Hz and a generous port area of 68 sq in. Uniquely for a Mega series subwoofer, the M-series also opens up the possibility for sealed (2.0 cu ft) and IB (Infinite Baffle) applications, offering unparalleled versatility for diverse installation needs and acoustic goals. Its compact Outside Diameter of 15.51” and Mounting Depth of 12.06” provide flexible installation options.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.

Great deal

### ⭐⭐⭐⭐⭐ Deeeep BASS
*by J***Y on November 18, 2025*

Best speaker I will ever own! This is a 70 lbs sub

### ⭐⭐⭐ False advertising. Maybe a fake dupe.
*by A***N on October 4, 2025*

So, I have not tried this yet. But 2 things. 1. The box you recieve says 1750 watts. Not the advertised 2000 watts. 2. The magnet is half the size as advertised. So. This is a scam I think.
