X Series

X-10/12/15/18:

The X 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, 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. We mate these new platforms to a triple stacked 190mm diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4" p-p travel before mechanical bottom). This motor powers a 3" diameter 4-layer CCAW coil wound on a thick, black aluminum former to incredible levels of excursion.

The X series was designed from the ground-up to become the new standard in the low-frequency / small ported box subwoofer category. They will work in anything from our traditional very small enclosures (such as the SA and Z v.3 series) up to about 50% larger than those suggestions for the maximum amount of low-frequency extension. These enclosures sizes are smaller than those recommended for many other woofers on the market today -- all the while retaining industry leaded levels of low-end output.

The X series is really a different kind of woofer due to it's incredibly linear suspension. They are designed for the LOWEST level of bass extension possible -- they are not what I would consider SPL drivers; but they will get extremely loud and clean. If you are after the lowest possible extension the X series is the driver for you.

Due to the extremely low level of suspension induced distortion the typical "punchy" upper-bass peak in the 40s-60s Hz range that occurs with traditional woofers when pushed to high excursion does not occur. This "punch" is caused by a tightening of the suspension over stroke leading to increased FS and Qts figures -- in other words it is distortion that some consider to be pleasing; but distortion none-the-less.

For customers after a more "traditional" sound we are developing a suite of "SPL" cones and spiders. These will retain as much of the high stroke of the stock suspension as possible but will increase the static FS and offer more suspension tightening over stroke. We expect these parts to be available in the 1Q of 2014.
