Sundown Audio (Z-Series)

Key Features and Improvements:

1. Custom Tooled and Patented Frames: The Z v.6 subwoofers are built with Sundown’s custom-designed and patented frames, ensuring a robust and precise structure. These frames are specifically designed for the Z v.6 series and are optimized for high excursion and performance.

2. Massive Motor Structure: The Z v.6 features a quad-stacked 240mm (9.45”) diameter motor structure with a 100mm (3.94”) magnet stack height. The motor design includes a hyper-extended pole and extreme clearances, allowing for over 4 inches of peak-to-peak travel before mechanical bottoming out, effectively making the subwoofer "bottomless."

3. Enhanced Magnetic Strength and Excursion: The motor assembly has been upgraded with thicker top and back plates compared to the previous models, resulting in increased magnetic strength and greater excursion potential. This makes the Z v.6 more powerful and capable of producing deeper bass than its predecessors.

4. 8-Layer Voice Coil: The Z v.6 series uses a 3-inch diameter 8-layer flat wire aluminum voice coil, which is an upgrade from the 4-layer coil used in the Z v.5. This change provides higher motor force and more output, meeting the demand for stronger performance.

5. Advanced Voice Coil Ventilation: To handle the increased power and prevent overheating, the Z v.6 features enhanced voice coil ventilation, including a high-velocity pole vent, heavily vented magnetic gap, and newly added machined channels around the pole piece. These improvements help maintain cool operating temperatures even under heavy use.

6. Versatile Enclosure Compatibility: The Z v.6 subwoofers are designed to excel in small ported enclosures, similar to those used for other Sundown Audio subwoofers, but they also perform well in larger enclosures, offering more low-end extension if desired.

7. Linear Suspension Design: The Z v.6 subwoofers are engineered with an incredibly linear suspension, ensuring the lowest possible bass extension in small enclosures while keeping distortion to a minimum. This makes them ideal for audiophiles and competitors who demand deep, clean bass in their systems.
