Features 5

  • 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.

  • 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.

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.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 3" diameter 4-Layer Round Wire Aluminum Voice Coil wound on a thick aluminum former, driving an incredible 35mm one-way linear excursion. This extreme excursion capacity ensures deep, impactful bass reproduction with exceptional clarity and minimal distortion, even at punishing volumes. Its RE (Ohms) of 2.22 and BL (NA) of 17.484 contribute to its formidable performance.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 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 quad stacked 200mm (7.87”) diameter motor structure with a 20mm thick top-plate.Superior Thermal Management for Longevity: To ensure sustained high performance, the M12 incorporates Sundown's highly efficient high-stroke coil ventilation system, originally developed for the 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 cooling mechanisms effectively manage coil temperature, allowing the M12 to perform flawlessly even during extended, demanding use.Optimized Enclosure Flexibility: The M-series was designed from the ground-up to excel in the low- frequency / small, ported box subwoofer category. It is primarily optimized for 2.5 cu ft net ported enclosures with a recommended tuning of 32Hz and a 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. Its compact Outside Diameter of 12.67” and Mounting Depth of 10.88” provide flexible installation options.Industry-Leading Low Distortion: The M-series is a different kind of woofer, thanks to its incredibly linear suspension and the inclusion of a magnet inner-diameter aluminum shorting ring. This ensures superior inductive distortion performance, resulting in exceptionally clean, undistorted, and highly accurate bass reproduction. We are confident that the M-series will set a new industry standard for value in high-performance, low-distortion subwoofers.

Awesome sub
Size: 12" - Dual 1 Ohm
Sub is awesome. It has a lot of the same qualities as the higher end Z line but at a cheaper price which makes it a great bang for your buck woofer. Sound quality is great as well and sounds good on the highs and the lows especially. Overall great sub

Best sub I've ever owned.

Not too sure
Size: 12" - Dual 1 Ohm
They arrived in good condition. But i feel like there is something wrong with one of them. Im running both speakers at way below rated power, but one of them always gets hot. I know they are wired in the correct polarity, and they show proper readings for coil impedance. Im probably clamping about 12 to 1500 watts in total going to the pair. They are supposedly rated fpr 1750 rms each, which is also not what the product description says they are, it clearly says they are 2k rms. So they need to stop false advertising that. And these are dual 1 ohm subs, I have them paralleled at the box using an smd 4 channel terminal cup, and I have them series connected to the amp, to show a 1 ohm load. And for whatever reason 1 of them gets really hot after playing for a short period of time. I have the power to push these to the max ratings and beyond, but im afraid this one is gonna burn up soon, and only a few weeks after receiving them. Over 650 bucks each after taxes, and performing like this, makes me not want to buy any more sundown subs. And no im not clipping them, if I was both speakers would be getting hot and only 1 is getting hot. And im talking after running for about 15 or 20 minutes on music, not test tones, and at way below rated wattage. 600 to 750 watts per sub. Im tearing everything out soon and im building a new box for my trunk and hopefully when I put everything back in it all works as advertised. But initial impression is the M series may not be worth what they cost. Take that for what it's worth. ... show more
