Z SERIES (Discontinued)

The Z v.4 series is the second 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 220mm diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing over 4″ p-p travel before mechanical bottom). This motor powers a 3″ diameter 8-layer flat wound Aluminum coil wound on a thick, black aluminum former to incredible levels of excursion.

As with the X series; Z v.4 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 (like the SA and Z v.3 series) up to about 50% larger than those suggestions for the maximum amount of low-frequency extension.

The Z v.4 series, likes it’s little brother 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 while maintaining low levels of distortion. They are NOT a peaky SPL woofer — these are true low distortion, high excursion bass transducers!

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. In simpler terms — the Z v.4 series frequency response does not change much over it’s full excursion range provided a consistant and flat response at any volume level. Once you experience and re-listen to all of your favorite music on a low distortion driver you are unlikely to go back!

Compared to the X series the Z v.4 carries a higher power rating, has a much larger motor, addes a magnet ID faraday ring (both feature a pole cap faraday ring), and features a stiffer suspension. You can think of the Z v.4 as a bigger version of the X series with even more output and power handling potential. Both drivers have a very similar sound.
