Pairing flexibility and rugged design make it a practical centerpiece for your outdoor sound.

Durable, paint-ready enclosure

The molded resin enclosure is designed to be painted to match your landscape, helping it blend with existing decor while resisting fading over time. It is approved for in-ground use, which adds to its versatility. In addition, the unit can function as a plant stand or pedestal table when you want to rearrange the space for entertaining.

The SUB100 features Capacitive Coupling Technology and a 10-inch long-throw Dynamic Balance driver to deliver deep, effortless bass. An integrated crossover provides configuration flexibility, allowing you to tailor bass response to your satellite speakers and space without extra hardware.

Security and practicality are also considered.

The weatherproof, marine-certified build provides reliable performance across seasons, making it a solid addition to an outdoor entertainment setup.
