Depending on what motor we have in stock, you may end up with a rev1 or rev2 motor. Please note rev1 and rev2 motors will work with each other and look nearly identical.

Please understand that this is a refurbished subwoofer.

Explanation of what it means to be refurbished: The sub may have scratches, blemishes and will not look 100% brand new.
We rebuild a previously used working motor with a used frame (unless a new frame is requested upon purchase), and install brand new parts inside (coil, triple joint ring, spider, cone and dust cap).

The subwoofer will function just as new and comes with a 30-day guarantee against build defects.

It will take on average 2-3 weeks for a refurbished subwoofer to be built and shipped.

Once your order is placed, you will receive a confirmation email. No other updates or emails will be sent until your order is completed at which point you will receive an email with tracking information.

INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE

The Z v.4 Rev.2 is the second step up in Sundown’s “ultra-high excursion” subwoofer lineup. The 10, 12, and 15″ models feature Sundown’s custom tooled and patented frames (US Patent Numbers D691596, D691597, and D691598) and the 18″ model uses the tried and true 18″ 6-spoke with a custom tooled adapter to allow for a full 10″ diameter spider. Optionally our custom tooled 18” frame is available for an extra charge (US Patent Number D741841) – this frame utilizes an 11” spider.

We mate these new platforms to a triple stacked 220mm (8.66”) diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4″ p-p travel before mechanical bottom). Compared to the X v.2 motor both the top & back plates are twice as thick allowing for even more magnetic strength. This motor drives a 3″ diameter 8-Layer Flat Wire Aluminum Coil wound on a thick aluminum former to incredible levels of excursion. Starting with the Rev.2 we use 100% American made voice coils & build each unit in-house here in North Carolina.

The Z v.4 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.4 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.

One of the most obvious changes from the Rev.1 is that the motor ventilation has been significantly improved – we increase the gap venting from 6 vents to 16 vents in order to more evenly spread the air-flow over the coil & also chamfered the vents to increase their air-flow potential. The pole cap was further optimized to provide more aerodynamic flow under the dust-cap. The Rev.2 was additionally upgraded to the all-new Mega-Roll v.2 surround which is a more linear & more rugged update to our world-famous Mega-Roll v.1 surround design.
