Atrium Sub100

Outdoor 10" Subwoofer


Housed in a moulded and sealed acoustically ideal resin enclosure and marine-certified with IPX66 rating, our guarantee of years of weather-proof outdoor performance.

Dynamic Balance®

Massive 10-inch long-throw Dynamic Balance® driver technology eliminates driver distortion for deeper, cleaner bass even at higher volumes.

Capacitive Coupling Technology

Dual 2-inch voice coil design reproduces bass from both stereo channels, producing more power in the lower frequencies with the help of Capacitive Coupling Technology. You get big outdoor bass for big outdoor impact.

Designed to Blend In

Sub100's enclosure may be painted to match your landscape design, the color-impregnated resin will never fade and naturally blends in with your outdoor seating - even use it as a plant stand or pedestal table.

Safety and Security

Includes 1 metre Cl3 rated 4 conductor direct burial pigtail cable. No exposed wiring gets in the way of the weed whacker.

Eye-bolt security anchor and screw-down points for added stability and security.


Maximum wiring flexibility with built-in high-performance crossover technology. The dual-voice-coil Sub100, with built-in low-pass filters, can be connected directly to its own amplifier channels for independent volume control.

The Subwoofer for All Seasons

Heavy-duty bass performance and heavy-duty all-weather durability combine to deliver indoor-level bass impact outdoors or in your home's transitional areas. The Sub100 is the perfect complement to a set of Sat300s, and rounds the system out with the full dynamic performance of a high-end audio system. Paint it to match the décor in your sunroom or by the pool. With serious bass fun, the Sub100 is the life of the outdoor party!

Aluminium Grille

The included grille protects the woofer and will hold up in the outdoor environment.
