Description

The fourth version of Sundown Audio’s acclaimed E series has been refreshed for 2020. The v.4 update is a minor refresh from the v.3 featuring a new custom-tooled, stronger stamped steel frame and a upgrade to the directional forced-air cooling spacer.

Sparked Innovations is a Certified Sundown Audio Recone Specialist. All rebuilt woofers come with a 90-day warranty from Sparked Innovations that covers workmanship. Since a subwoofer should never blow if operated within the manufacturer’s specifications, the only reason it would fail is if we did something wrong in the recone process.

NOTE: B-stock refurbs will have cosmetic scratches, scuffs, or even gouges in the metal of the basket or on the magnet. None of this will affect performance.
