MartinLogan Outdoor Living Foundation Subwoofer
Best in-ground subwoofer for homeowners seeking powerful, hidden outdoor bass.
This is the rare outdoor subwoofer that prioritizes landscape aesthetics as much as low-end performance. By burying the enclosure and leaving only a subtle cap visible, it delivers serious, ground-shaking bass without cluttering your patio design. You sacrifice the ability to move it around, but you gain a permanent, weather-proof foundation for your backyard sound system.
