Sundown Audio ZV7 18" Single Bundle
Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order, and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. Approved returns may be subject to a restocking fee.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

This Listing Includes: (1) Sundown Audio Z-Series ZV7 18″ Subwoofer
The Z v.7 is the third step in Sundown’s 2025 ultra-high-excursion lineup after the M and X v.4 series, built on the custom-tooled, patented “mega-platform” frame. It pairs that frame with a quad-stacked 265mm (10.43″) motor and a 100mm (3.94″) magnet stack — the largest motor ever used on a Z series sub — driving a 3.3″ 4-layer round-wire aluminum voice coil with a 95mm winding length. A patent-pending airflow-directing pole cap, six pole-OD channels, sixteen gap vents, and a cross-drilled top plate keep the coil cool, while a 9mm magnet-ID Faraday ring and pole-extension inductance sleeve deliver highly linear inductance. The result is 42mm of one-way linear excursion by 70% BL with an extremely uniform curve, designed for the lowest bass extension possible in a small ported enclosure with very low distortion.
