MartinLogan Outdoor Living Foundation Sub 8 In-Ground Subwoofer

Deep, Powerful Bass. Beautifully Hidden Outdoors.

Bring the full impact of your favorite music to your outdoor living space with the MartinLogan Outdoor Living Foundation Sub 8, a premium in-ground subwoofer engineered to deliver rich, powerful bass without disrupting the beauty of your landscape.

Designed for patios, gardens, pool areas, and backyard entertainment systems, the Foundation Sub 8 adds the low-frequency performance that conventional outdoor speakers often lack.

Exceptional Bass Without the Visual Clutter

The Foundation Sub 8 features a high-excursion 8-inch woofer with dual 8-ohm voice coils, delivering impressive low-frequency performance while offering flexibility for custom outdoor audio installations.

Its rugged enclosure is designed for direct burial, with only a discreet mushroom-style canopy visible above ground. This clever design protects the speaker from the elements while allowing bass to disperse naturally throughout your outdoor listening area.

Whether you're entertaining guests, relaxing by the pool, or enjoying an evening on the patio, the Foundation Sub 8 adds depth, warmth, and impact to your outdoor entertainment experience.

Engineered for Year-Round Outdoor Performance

Constructed from durable, weather-resistant HDPE material, the Foundation Sub 8 is designed to withstand demanding outdoor conditions.

Its IP58-rated enclosure provides excellent protection against dust and water, making it an ideal choice for permanent landscape audio installations.
