Sundown Audio Zv7 18" D2 Subwoofer | 3500W RMS
The Z v.7 is the third step up in Sundown's 2025 "ultra-high excursion" sub-woofer lineup after the M and X v.4 series. All models (12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691597, D691598, and D741841) – the Sundown “mega-platform.” Please note – the Z v.7 is not available, aside from special orders, in 10s due to the motor size.
We mate these new platform frames to a quad stacked 265mm (10.43”) diameter motor structure with a total magnet stack height of 100mm (3.94”) featuring a hyper-extended pole and extreme clearances (allowing over 4" p-p travel before mechanical bottom effectively making it bottomless). This is, by far, the largest motor we have ever produced on a Z series sub-woofer. The motor force factor (BL^2/RE) is ~50% higher than the previous generation Z v.6 series.
This motor drives a 3.3" diameter 4-Layer Round Wire Aluminum Voice Coil wound on a thick aluminum former. These new round wire coils use a special Sundown designed “fat wire” winding method to handle significant amounts of power and abuse.
Based on Sundown's years of experience with the Z v.4, 5, and 6 series we've also improved the voice coil ventilation yet again. The Z v.7 features an entirely new and patent-pending airflow directing pole cap, six pole OD channels, SIXTEEN gap vents, and a cross-drilled / slotted top plate to keep the voice coil running cool under extreme conditions.
The Z v.7 motor also features a 9mm thick magnet ID Faraday ring which is locked into both the top and back plates. This ring combined with an all-new pole-extension inductance sleeve gives the Z v.7 the most linear inductive performance of any mega-platform sub-woofer to date. As if all of this were not enough to cement the Z v.7as a legend... we were also able to achieve 42mm of one-way linear excursion by 70% BL with an extremely uniform curve via our extensively FEA optimized motor and 95mm long voice-coil winding length.
The Z v.7 series was designed from the ground-up to become the new standard in the low-frequency / small, ported box sub-woofer category in this price range. They will work in the same enclosures that are commonly used for Sundown Audio's mega-platform sub-woofers.
The Z v.7 series, like its other mega-platform brethren, 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.
