Black Series 12" In-ground Subwoofer with 12” Polypropylene Cone and 500W Power Rating - XSUB12

Your audio system doesn't have to have inferior sound just because it's located outside. You can still enjoy rich, crisp music in your very own backyard thanks to this Black Series 12" In-Ground Waterproof Subwoofer. This audio unit enhances the bass in your outdoor speakers while also blending into your surroundings. Using it in a commercial application? Simply choose 70V from the dropdown.

The Black Series XSUB is a 500W in-ground subwoofer designed for both commercial and residential environments. Designed with durable, weather-resistant components, the XSUB is buried underground with only the vent peaking from the surface. Installation is relatively simple, but considerations should be taken on placements and wire run.

 It provides high-end audio with an elegant, unobtrusive design. The XSUB kicks out earth-shaking low-end with a 500W power rating, and the durable 12” polypropylene cone includes rubber surround, not foam, so it will last through years of steamy hot summers and freezing cold winters.

For optimal performance, connect the XSUB series subwoofer to a mono subwoofer amplifier like the SAM300 and combine it with our landscape satellite speakers.  Additional system configurations can be created for up to eight pairs of speakers using multichannel amplifiers and/or series parallel wiring, meaning you get rich audio with clear, deep bass every time you step outside. The XSUB is also ideal for theme parks, shopping malls, restaurants, resorts, gardens and other outdoor spaces where bass can enhance the audio experience.
