Dynamo Outdoor Sub 100 In-Ground Subwoofer
The Dynamo Outdoor Sub 100 adds deep, satisfying bass to any outdoor living space without cluttering the view. Its 10-inch mineral-filled poly woofer with a high-power 2-inch voice coil is housed in a buried enclosure, leaving only an unobtrusive "mushroom cap" port visible above the ground.
Built for the Outdoors
Rugged, all-weather materials and completely weatherproof construction make it a natural partner for MartinLogan Outdoor Living satellites, extending true high-performance sound across the garden or patio.
All-Weather Subterranean Design
The high-density polyethylene enclosure, the same material used in underground water systems, withstands heavy rain and wide temperature swings and has been tested underwater and from −29°C to 85°C. The low-heat woofer is vented through the mushroom cap for constant fresh air while staying protected from the elements.

Caring for your Speakers and Amplifiers
To Keep your equipment safe these are some best practices to note. Please be advised that this is only to reduce the risk of misuse and is not an exhaustive list.
Speakers
- Speaker terminals are marked red and black, ensure your amplifier to the speakers are wired on the same colours
- Ensure no loose speaker wire from the red touches a loose wire from the black as this will lead to a short circuit and damage either the speaker, the amplifier or both.
- Not all speakers are designed to play at max volume, kindly consider the pairing of your amplifier and speakers
- Speaker cabinets cannot be replaced please handle with care.
AV & Stereo Amplifiers
- If your amplifier has HDMI ports, ensure all devices are off before plugging in the HDMI cable
- Turn off the amplifier before swoping out or adding speaker cable
- Amplifiers generate heat, place them in a well ventilated space. if possible avoid having anything on top of the unit.
- adding a surge protector can assist with power dips which are likely to damage your devices. Isotek and Furman are industry standard.
- Dusty environments can sometimes lead to accumulation of dust in the electronic components that might affect heat regulation
