Match amplifier power to the Sundown driver, since a ported alignment lets it take more of it than a sealed one would.
Read the guideSundown Audio SA Box Questions
Which Sundown Audio SA sizes do you build boxes for?
10, 12 and 15 inch, in single and dual cabinets. Each listing is cut for one size and names it in the title.
Does an SA-12 box fit every SA-12 generation?
The Professional Series SA-12 cabinet is built to fit the SA-12 Classic, v.2 and current generation, which share a basket. At 10 and 15 inch, each title names the generation it fits.
Sealed or ported for the Sundown Audio SA?
Sealed is smaller and holds its output below tuning; ported gives more output around its tuning from a larger cabinet. Every ported listing states its tuning and every listing states its net volume.
Do the dual boxes have separate chambers?
The Professional Series duals share one chamber and one port, so run two of the same model and coil.
Is the Sundown Audio SA included?
No. These are enclosures built to fit the Sundown Audio SA; the driver is sold separately. A listing that ships with the driver fitted says loaded in its title.
How should I wire the Sundown Audio SA?
The SA is built in dual 2 ohm and dual 4 ohm versions. Check the coil printed on your driver, match the final load to the amplifier, and run two of the same model and coil in a dual cabinet.
What warranty do these boxes carry?
It runs by series: 1 year limited on Performance Optimized, 2 years on Professional and Micro. The series is named in each listing title.
