The 2020 E Series v.4 subwoofers feature improved components, durability, and performance, making them the best E series yet.

The E series v.4 10″ D4 (500-watts) update is a minor refresh from the v.3 featuring a new custom-tooled, and stronger stamped steel frame.

The fourth version of our acclaimed E series has been refreshed for 2020. Since we introduced the first E series in 2012 we have sought to push the limits of entry-level woofers forward. Typical entry level woofers are highly limited in terms of linear excursion, mechanical ruggedness, and thermal performance – all of these bars have been raised once again for our fourth generation E series. 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 our directional forced-air cooling spacer.

The E series v.4 12″ D4 (500-watts) update is a minor refresh from the v.3 featuring a new custom-tooled, and stronger stamped steel frame.
