ZV5 SERIES

MSRP Starting at: $1004.99

The Z v.5 is the second step up in our "ultra-high excursion" subwoofer lineup after the X v.2 series and replaces the world-famous Z v.4 series. The 10, 12, 15, and 18" models all feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841).

We mate these new platform frames to a triple stacked 234mm (9.21”) diameter motor structure with a total magnet stack height of 102mm (4.01”) 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.2 motor both the top & back plates are thicker allowing for even more magnetic strength and excursion potential.

This motor drives a 3" diameter 4-Layer Flat Wire Aluminum Coil wound on a thick aluminum former to incredible levels of excursion. The Z v.5 now uses the same voice coil as the NS v.3 series in the stock configuration – which means it is now a much longer 4-layer compared to a shorter 8-layer found in the Z v.4 series. The 4-Layer coil is able to shed heat faster, has a much lower inductance, and has less mass all while allowing for a higher linear excursion and thus significantly less distortion. We leveraged the much larger motor to keep total motor force similar to the Z v.4 Rev.2 while also having all of the other advantages listed prior. We do also offer an optional 8-layer coil that offers a significantly higher motor force factor & thus a lower Qts.

Compared to the Z v.4 Rev.2 we also increased the thickness of the Magnet ID shorting ring by 33% to further reduce static inductance and inductive distortion over strong. Based on our years of experience with the Z v.4 series we improved the voice coil ventilation to be even more effective and feature reduced turbulence in order to reduce voice coil temperatures & increase reliability.

The Z v.5 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 you are used to using for Sundown Audio subwoofers, although, the will tolerate enclosures up to about 50% larger than those if you desire even more low-end extension.

The Z v.5 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.

X-ZV4-NSV3-TEAM BASKET

CUSTOM TOOLED BASKETS (10/12/15/18” Sizes)

Our proprietary 10/12/15/18" baskets (US Patent Numbers D691596, D691597, D691598, and D741841) were originally designed and tooled up in 2012 (2014 for the 18" model) in order to create what we call the "new platform" for Sundown subwoofers. We were not satisfied with the industry standard baskets when it comes to our high-end woofers (X series and higher) so we became the first "niche" company to design & tool our own entire series of ultra-high excursion baskets.

The new baskets were originally accompanied by the Mega-Roll v.1 surround technology in 2012 and followed up with the improved Mega-Roll v.2 surround technology in 2015 in order to push the boundaries of linear excursion capacity enabled by the new baskets. The new platform frames all support at least 4" p-p stroke (as much as 6" on the 18" model) so they were designed from the ground-up to be ready for the future of high linear excursion. Each basket also supports a much wider spider than the industry-standard sizes to compliment the Mega-Roll surrounds.

Our Sundown baskets were also tooled to be the strongest baskets ever created in order to support monstrous motors like the Team Sundown. The 18" model is a full 10 pounds of cast aluminum! They were also tooled with a "solid base" design (meaning no integrated venting) to mate with our specially designed venting rings. It is actually more expensive to make a basket this way since it uses more aluminum but our vent ring technique is much more effective than wide-open venting. The solid base also ensures the maximum level of structural integrity in this area.
