The Sundown M-Series is an all-new "entry-level" subwoofer in our Mega series - all Mega series subwoofers (10,12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841) and our Mega-Roll surround.

When we say "entry-level" this is only by comparison to its big brothers in our own Mega line - X,Z,NS series and higher. The M series was built for intense bass with stellar low-frequency performance at industry-leading levels of low-distortion. It does this while looking amazing - with a new laser-etched back-plate design and special M-series magnet boot design.

For the M-series we mate out Mega series frames to a quad stacked 200mm (7.87”) diameter motor structure with a total magnet stack height of 88mm (3.46”) featuring a hyper-extended pole and extreme clearances (allowing 59.5mm to mechanical bottom effectively making it bottomless - this is 4.68" peak-to-peak). At Sundown we always do things to the extreme so even our "entry" level M-series features a full 20mm thick top-plate to finish the efficient magnetic circuit. We did all of this while still optimizing the cost to offer the absolute best-value to our customers.

This motor drives a 3" diameter 4-Layer Round Wire Aluminum Voice Coil wound on a thick aluminum former to incredible levels of excursion. The new coil in the M-series was developed for both the M and X v.4 series and features a very special winding (invented by Sundown for the X-8 series originally) that allows the best winding packing density in the gap for both the D1 and D2 options. This coil is so massive that it allows even our M-series to achieve a full 35mm one-way linear excursion. We are truly setting a new industry standard with the M-series.

Based on Sundown's years of experience we've included our highly efficient high-stroke coil ventilation system developed for the X and Z series originally. The M-series 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.

The M-series was designed from the ground-up to become the new standard in the low-frequency / small, ported box subwoofer category in this price range. Never before have we been able to offer such an incredible value in the Mega series. They will work in the same enclosure as our other Mega platform subwoofers, but the M-series also opens up the possibility for sealed and IB applications. This is something that was not well suited to any other previous Mega platform subwoofer.

The M-series is really a different kind of woofer due to its incredibly linear suspension. They are designed for the LOWEST level of bass extension possible in a small enclosure while maintaining extremely low levels of distortion. This is all thanks to the Sundown Mega-Roll surround & proprietary Sundown PG linear suspension (fully computer optimized). As with most subwoofers from Sundown the M-series features a magnet inner-diameter aluminum shorting ring for superior inductive distortion performance as well.

We are quite certain that the M-series will go down in car audio history as one of the best low-distortion subwoofers per-dollar of its time.
