Sundown Audio Z-Series ZV6 18" 3250W Subwoofer Z v.6
The Z v.6 is the second step up in Sundown's "ultra-high excursion" subwoofer lineup after the X v.3 series and replaces the world-famous Z v.5 series. All models (10,12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841).Sundown mates these new platform frames to a quad stacked 240mm (9.45”) diameter motor structure with a total magnet stack height of 100mm (3.94”) featuring a hyper-extended pole and extreme clearances (allowing over 4" p-p travel before mechanical bottom effectively making it bottomless). Compared to the X v.3 motor both the top & back plates are thicker allowing for even more magnetic strength and excursion potential. For the Z v.6 the top plate is another 5mm thicker than even the outgoing Z v.5 series!This motor drives a 3" diameter 8-Layer Flat Wire Aluminum Voice Coil wound on a thick aluminum former to incredible levels of excursion. The Z v.6 now uses the same voice coil as the NS v.5 series. The Z v.5 utilized a 4-layer voice coil – the change to an 8-layer was to answer our customers desire for higher motor force (more output) and it does just that!Based on Sundown's years of experience with the Z v.4 and Z v.5 series we've also improved the voice coil ventilation to be even more effective. The Z v.6 features a high-velocity pole vent, a heavily vented magnetic gap, and (all new for the v.6) machined channels in four places around the pole piece itself.The Z v.6 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. They will work in the same small enclosures that are commonly used for for Sundown Audio's subwoofers, although, they can be used with enclosures up to about 50% larger than those if you desire even more low-end extension.The Z v.6 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.

Sparked Innovations Sparked Innovations 18" Bass Blaster Car Audio Subwoofer 2000W DVC
The Bass Blaster subwoofer series is a truly unique blend of car audio nostalgia and modern technology. Designed and built as a product of love for car audio, this subwoofer will look as good in your installation as it will sound. As lifelong enthusiasts ourselves, we knew the demands this subwoofer would need to meet. The engineering expertise of Jacob Fuller, founder of Sundown Audio, has led to a subwoofer that can take the abuse of high-powered systems that the modern-day enthusiast likes to throw at everything. Advanced cooling techniques, high-excursion linear suspension, and classically inspired aesthetics mean The Bass Blaster will give you the best-sounding bass, for a long time, as you turn the heads of anyone that takes a look. Design Our philosophy with The Bass Blaster was to recreate the feel of car audio from our youth. The blue surround is not just our branding color, it is an homage to woofers of the 1990s that used brightly colored surrounds as a signature look. The balance of the blue to the grey/silver basket and cone harkens back to the early 2000s when some of our favorite woofer models sported a distinct style. The aluminum dust cap gives depth and texture to the woofer as a whole and adds rigid reinforcement to the cone body. The genesis of the design was the motor itself, the large vent for the four-inch coil caught our eye in car audio shops in the 1990s. Jacob Fuller captured that look while tapering the vent and adding a pole cap so as to not compromise modern cooling techniques for the best performance-to-aesthetics ratio possible. Topped off with the metal mesh over the magnet slugs, The Bass Blaster is the 90s/2000s woofer we all wish we had in our teens, but even better that we have it in our 40s.

Sundown Audio Z-Series ZV7 18" Subwoofer
The Z v.7 is the third step up in Sundown's 2025 "ultra-high excursion" sub-woofer lineup after the M and X v.4 series. All models (12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691597, D691598, and D741841) – the Sundown “mega-platform.” Please note – the Z v.7 is not available, aside from special orders, in 10s due to the motor size. We mate these new platform frames to a quad stacked 265mm (10.43”) diameter motor structure with a total magnet stack height of 100mm (3.94”) featuring a hyper-extended pole and extreme clearances (allowing over 4" p-p travel before mechanical bottom effectively making it bottomless). This is, by far, the largest motor we have ever produced on a Z series sub-woofer. The motor force factor (BL^2/RE) is ~50% higher than the previous generation Z v.6 series. This motor drives a 3.3" diameter 4-Layer Round Wire Aluminum Voice Coil wound on a thick aluminum former. These new round wire coils use a special Sundown designed “fat wire” winding method to handle significant amounts of power and abuse. Based on Sundown's years of experience with the Z v.4, 5, and 6 series we've also improved the voice coil ventilation yet again. The Z v.7 features an entirely new and patent-pending airflow directing pole cap, six pole OD channels, SIXTEEN gap vents, and a cross-drilled / slotted top plate to keep the voice coil running cool under extreme conditions.The Z v.7 motor also features a 9mm thick magnet ID Faraday ring which is locked into both the top and back plates. This ring combined with an all-new pole-extension inductance sleeve gives the Z v.7 the most linear inductive performance of any mega-platform sub-woofer to date. As if all of this were not enough to cement the Z v.7as a legend... we were also able to achieve 42mm of one-way linear excursion by 70% BL with an extremely uniform curve via our extensively FEA optimized motor and 95mm long voice-coil winding length. The Z v.7 series was designed from the ground-up to become the new standard in the low-frequency / small, ported box sub-woofer category in this price range. They will work in the same enclosures that are commonly used for Sundown Audio's mega-platform sub-woofers. The Z v.7 series, like its other mega-platform brethren, 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. Physical Dimensions: Download

Sundown Audio U-Series v.2 18" Subwoofer
2000 Watts RMS / 4000 Watts Peak Dual 2 or 4 ohm voice coils Optimized for small ported or bandpass enclosures Aluminum 3” voice coil former for superior heat dissipation High-temperature copper voice coil Double stitched surround Heavy-duty cast basket Spring-loaded terminals accept up to 8-gauge wire Stitched-on heavy-duty tinsel leads Solid pole with vent channels and aluminum shorting ring cap Rear gap-venting Top-Plate Cooling Channels Designed to be at home in the competition lanes or playing your favorite music, the U Series is the premier “standard suspension” woofer in the Sundown lineup. A double-stacked 9.4-inch wide ferrite magnet system is coupled to a thick top plate. A thick set of shorting rings are used inside the magnets and on the pole cap, smoothing out frequency response while doubling as a heat sink and airflow guide. A custom aluminum frame was designed specifically for the U Series. It’s substantially thicker and equipped with heat dissipation ribs at the bottom of the frame. The U v.2 motor also features an extended pole piece to keep the coil under perfect control under high stress. The coil temperature is controlled with machined, high-velocity pole channels and a series of 16 direct air-gap vents in the back plate. Dimensions

Sundown Audio SA-Series v.2 18" Subwoofer
1250 Watts RMS / 2500 Watts Peak Dual 2 or 4 ohm voice coils Vented magnetic gap & pole piece Aluminum 2.75” voice coil former for superior heat dissipation Innovative high velocity, cast aluminum vented frame spacer ring Magnet ID faraday ring for smooth acoustic response High-temperature copper voice coil wire Spring-loaded terminals Stitched-on double “XL” tinsel leads This SA-10/12/15 v.2 series is a top-down upgrade from the original SA series. The 2.75” coil punches way above its weight, outperforming many 3” coils without the adding weight & with the added advantage of a wider spider. We are able to perfectly balance the mass, motor force, and suspension stiffness for the intended power level. The motor also features a large magnet shorting ring (faraday ring) to reduce distortion and deliver smoother response across the entire acoustic spectrum. The motor & coil setup is mated to an extremely robust multi-layer spider with fully tied-on & doubled-up “XL” tinsel leads. A competition-grade paper cone, strong foam surround, and cast aluminum frame are used to complete this masterpiece. On top of the ~19mm of one-way linear excursion we have an x-mech limit of 37mm one-way before coil bottom making it nearly "bottomless." The 18" model features a larger diameter motor to drive the higher mass. Enclosure Designs .Zip File

Sundown Audio InHuman 18" 7500W Subwoofer
Meet the Sundown Audio InHuman — the subwoofer that exists only for the moments when "loud" has already lost all meaning. This is 7,500 watts RMS of purpose-built devastation: an 18" limited-edition monster riding a Quad-Stack 330mm ferrite-and-neo motor structure that generates a force factor roughly 2.5x that of the legendary SDDN, all anchored to Sundown's patented Tooled Frame (US D741,841). With a custom-tooled carbon fiber cone, a 5" eight-layer flat-wound aluminum voice coil, 41mm of linear one-way excursion, and an FS that drops to 18–20Hz after break-in, the InHuman was engineered from the ground up for one job — annihilating 6th-order bandpass demo builds and producing hurricane-force wind. At nearly 190 pounds with mandatory motor support, this isn't a subwoofer you install; it's a statement you commit to. Buckle up.
