Versatile Applications

Along with the new 8” woofer, the 10” and 12” S-Series subwoofers have been re-designed from the ground up. The mounting depth of the 10” and 12” subwoofers are almost 1” more shallow than previous models at just over 4.5” for the 10” models and just over 5” for the 12” models, allowing them to fit into a wide variety of installation applications.

Versatile Applications

Custom-Stamped Steel Frame

Each S-Series Subwoofer uses a custom-stamped steel frame. These high-strength frames were designed to withstand the rigors of the improved S-Series motor. They have frame leg vents as well as vented back plate to help cool the subwoofer voice coil and motor parts, plus a shallow design to help fit in smaller spaces.
