The X v.2 series is the first driver in the Sundown woofer line-up to offer our "ultra-high excursion" suspension and frame designs. The 10, 12, and 15" models feature our 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 & changes the coil configuration availability changes to D1 & D2.

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). This motor drives a 3" diameter 4-layer CCAW coil wound on a thick aluminum former to incredible levels of excursion. For the v.2 revision we upgraded the coil to a new “black coil” design which handles significantly more heat than the coil form the X v.1 series.

The X v.2 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 X v.2 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 v.1 series is the much larger motor structure (220mm vs. 190mm on the v.1 series). The motor ventilation has also been improved and we also 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.

    Pair of Sundown X v2 15 D4

    Posted by Joseph Ward on Jan 20, 2024

    Got a pretty sweet deal when I purchased the pair of subs, and I'm pleased with the delivery time frame to receive the order. Free air tested the pair wired to 4 ohms and they played perfectly out of the box; wired them to 1 ohm and they hammer nicely at rms power to both subs.

    I upgraded from the scar vfx and these are well worth the upgrade they are way cleaner bass and hitting harder. Using same amplifiers so I can really tell the difference also they aren't broke all the way in yet so they will hit a little bit harder.

    They play low, no smells, seems like whatever you throw at them they will take it, I have them powered by JP43, experimenting w/ 1ohm and 2ohm, in the box and with the tune to my ear they really like the 2ohm, these are heavy duty and you will be happy you bought them for an everyday set up but you need the space indefinitely, trust me, I have 2 of these stuffed in a 06 honda civic, plenty of flex also, so you might need some bracing depending on the car
