MartinLogan Outdoor Living Foundation Subwoofer

This subwoofer is designed to be buried in your yard, leaving only the discreet canopy visible above ground. You will need to excavate a hole appropriate for the unit's 22-inch by 13.8-inch dimensions, ensuring proper drainage at the base to protect the enclosure.

Yes, it features rugged, all-weather construction specifically engineered for year-round outdoor use. It is built to withstand exposure to the elements, including rain, snow, and temperature fluctuations, without compromising sound quality.

This subwoofer has an impedance of 4 ohms and handles 200 Watts RMS. You will need an external amplifier capable of driving a 4-ohm load at that power level to get the best performance from the 8-inch driver.

While it is compact, the high-excursion 8-inch driver is optimized for outdoor environments, delivering a frequency response down to 47 Hz. It provides a solid, impactful low-end foundation for your outdoor audio system, though it is best paired with dedicated satellite speakers for a full-range sound.

Because this is an in-ground subwoofer, it requires soil or a similar substrate for installation. It is not designed to be mounted on top of a hard deck surface; it must be buried to achieve the correct acoustic loading and discreet aesthetic.
