DC Audio DC Audio 8M3 8" 600 Watt RMS/1200 Watt Peak Dual-2-Ohm Car Audio Subwoofer/Sub
The m3 8 is an 8" long X-Max subwoofer. Long hours in the R&D department is what it took to develop the newest version of our 8" subwoofer. We designed a tall roll stitched surround, oversized spiders, and a tall cast frame that allows for extreme amounts of cone travel. All of these newly designed parts allow for lower frequency reproduction. The bolted down spaced spider design keeps it all linear. The m3 8 uses a gap cooled design to allow the 2" copper coil to thermally take more power than other 2" coil motors with the traditional pole venting. Key Features • Extremely rigid non-pressed paper cone assembly • High Roll Stitched Multilayered reinforced polymer foam surround • Rigid propylene dust cover with White DC logo • Bolted down & spaced Linear roll spiders • Sewn flat heavy duty tinsel lead wire • Custom Cast aluminum black frame • FEA analyzed and optimized motor assembly – Fully CNC machined • Rubber mounting gasket and custom tooled motor boot. • DVC 2.0” Copper voice coil.

Sundown Audio M-Series M12 2000W Subwoofer
2000 Watts RMS / 4000 Watts Peak Available in Dual 1 and Dual 2 Ohm Configurations Mega Roll Surround and Frame Etched All Black Backplate Quad Stack Magnet Structure 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.

Sundown Audio SA-1T Tweeter
The all-new 2025 Sundown SA speaker series has been designed to make a statement. What statement, you may ask? That Sundown Audio can be just as serious about SQ as we are about SPL. Many people already know this but our subwoofers – even the ones used for crushing demos – have some of the lowest distortion on the market. We are now bringing our unique approach to the more dedicated Sound Quality market.Starting at the upper end of the frequency spectrum we have the SA-1T Tweeter. The SA-1T features a 25.5mm silk dome (total 38mm including surround) driven by a powerful neodymium motor structure. The dome features a compact, tuned back chamber which helps it to achieve its extremely low FS around 700hz. This gives you an enormous amount of flexibility in choosing the crossover. The tweeter can be used as a 2-way with the 6.5M or the 8M models or as part of a three way with either and the 3M model. In addition to the low FS and smooth response the SA-1T has a very high 92dB sensitivity so it doesn't take much power to get loud enough for just about anyone. The SA-1T is the 4th generation SA tweeter building on the success of the tweeter found in the SA Component sets over three generations.Headed down the spectrum to the midrange we have the SA-3M. This "little" unit is something incredibly special and is a favorite project of lead product designer / founder Jacob Fuller. We really went all-out on this unit to address the "big 3" drivers of distortion. The SA-3M features 4.5mm of one-way linear excursion by 70% BL (with 8mm x-mech thanks to the custom tooled frame – so no bottoming out even on powerful dynamics) and over 6mm by CMS and LE definitions on Klippel. There is essentially NO risk of the driver reaching linearity limits in most applications. The beefy motor structure is a combination of ferrite and a neodymium pole cap magnet to help us reach 84.5dB sensitivity at 1-watt. There is a double LE treatment internal to the motor via both a copper pole sleeve and an aluminum magnet ID shorting ring allowing the SA-3M to play full-range to beyond 20khz (although, for several reasons, we do suggest using a tweeter for the top-end). On the bottom end they can be high-pass crossed over at 300hz effortlessly with 150-watts of power handling (thanks to the 28mm diameter, extra-long voice coil) or even lower if needed, with less power, due to the incredibly high linear stroke. The suspension system, surround and spider, of the SA-3M took over a year of FEA simulations and testing to reach perfection and is just as important as the motor to the resulting low distortion. We gave the suspension just as much attention as we would for a full blown high-stroke subwoofer. To finish off this masterpiece we tested several different types of woven carbon fiber cones & dust caps to achieve the best FR possible.To finish off the 2025 SA speaker line we created the SA-6.5M and the SA-8M. Both of which can be used as a mid-bass or mid-range speaker depending on your application. Both drivers feature the same attention to detail as the 3M regarding the carbon cone and dust cap, surround, and spider. All of these parts were fully FEA simulated and Klippel verified.The SA-6.5M features 5.9mm one-way linear excursion by 70% BL, 7mm by CMS, and 6.28mm by LE on Klippel. Thanks to the efficient motor venting and ample voice coil the power handling is rated for 110-watts full range / 200-watts with a 70hz HPF filter with a respectable 89dB sensitivity. As with the SA-1T this is a 4th generation SA speaker due to the SA component set from prior generations. For this iteration we optimized it further and also created a new custom-tooled frame. The revised frame is more aerodynamics and also allows for superior coil ventilation. As with most Sundown products you will find a thick magnet-ID Faraday ring as well.Last, but absolutely not least, we have the SA-8M which takes linear stroke to yet another level. We were able to achieve 9mm one-way linear by 70% BL and nearly 10mm by CMS and LE standards. As with the 3M, the 8M features a pole sleeve and magnet ID faraday ring for LE treatment. This unit is an absolute powerhouse for mid-bass, and we believe it will make big waves in the SQ world. On the output side it has a 91.5dB sensitivity and will handle 130-watts full-range / 250-watts with a 70Hz HPF thanks to the efficient motor venting and huge 2" coil. The SA-8M is all-in on SQ and output potential – the Sundown way!SA Series, Version 4 1" Soft Dome Tweeter PairSensitivity – 92dB50W RMS @ 3000hz 6dB Crossover50W RMS @ 3000hz 12dB Crossover65W RMS @ 5000hz 12dB Crossover
