MTX Audio SLH12U Sledgehammer 12" Subwoofer Enclosure

Bring your bass to life with the MTX Audio SLH12U Sledgehammer Custom 12" Enclosure. This premium enclosure features a unique slot port design to deliver loud, accurate bass. In addition, its satin black front provides a clean finish for your car audio installation.

Deep Bass with a Snappy Response

The SLH12U delivers a wide bass output bandwidth, reproducing deep low frequencies alongside punchy upper bass. As a result, it helps your subwoofer deliver depth and impact across a variety of music styles. Furthermore, its snappy response keeps pace with everything from sustained bass notes to fast kick drums.

Designed for MTX 12" Subwoofers

Designed to accommodate MTX 12" subwoofers, the SLH12U suits models from the RoadThunder range through to the TX8 Series. Whether you’re building a new bass system or upgrading your existing setup, it provides a purpose-designed enclosure option.

However, for MTX RFL Competition subwoofers running more than 2,000W RMS each, we recommend a custom-built enclosure tailored to the subwoofer and power requirements.
