Eight Audio Onyx S12 12'' Active Powered Subwoofer – Where powerful bass meets precision engineering. Designed to elevate your audio experience to new depths, this subwoofer is an impressive addition to any home theater or audio setup.

At the heart of the Onyx S12 is a high-performance 12-inch Long-Stroke Hard Paper Cone driver that delivers deep, thunderous bass with exceptional clarity. Whether you're watching explosive action scenes or listening to your favorite music, this subwoofer enriches the low-end frequencies, adding a whole new dimension to your audio content.

The Onyx S12 is driven by a robust built-in ICEpower amplifier, perfectly matched to the subwoofer's capabilities. With a power output of 300 watts continuous RMS, this active subwoofer ensures not only impactful bass but also consistent and controlled performance even during intense listening sessions.

To provide precise control over the subwoofer's output, We have equipped this Onyx S12 with versatile controls. The adjustable crossover allows you to blend the subwoofer's output seamlessly with your main speakers, creating a cohesive and well-balanced soundstage. Additionally, the variable phase control lets you align the subwoofer's output with the rest of your speaker system for optimal integration.

Floor shaking BASS

This subwoofer does its job perfectly. Both in music and movies the base is powerful enough to legitimately FEEL without having to be driven loud enough to drown out the other frequinces or feel uncomfortable.
