Atrium Garden System

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.  Innovative Sat300 satellite speakers can be planted in your landscaping, hung from your ceiling or the eaves, or installed anywhere you want to mix great sound with the great outdoors. Designed to mimic stylish lighting fixtures whilst delivering high-performance audio, Sat300s are full-range speakers that can blend into a wide range of landscapes and environments.  Paintable surfaces allow you to match the décor in your sunroom or by the pool. Heavy-duty bass performance, acoustic balance and tough all-weather durability combine to deliver full dynamic performance outdoors or in your home's transitional areas.  


Sub100 is housed in a moulded and sealed acoustically ideal resin enclosure and marine-certified with IPX66 rating and Sat300s withstand years of weather with mineral-filled polypropylene housing, 1mm aluminium grille & stainless steel hardware - our guarantee of years of weather-proof outdoor performance.

Dynamic Balance®

Massive 10-inch long-throw subwoofer driver; 3 1/2-inch long-throw midrange driver with 1-inch voice coil, vented pole-piece, rugged butyl rubber surround and composite cone; and 3/4-inch composite dome neodymium tweeter feature Dynamic Balance® driver technology to eliminate driver distortion for deeper, cleaner full range sound even at higher volume.


Sub 100 features a 200 Watt downward-firing subwoofer and delivers earth-shaking bass. Sat300s are capable of handling up to 100 Watts of power to deliver superb clarity, detail and high efficiency with less distortion, at both moderate and higher volume levels –even in outdoor environments.

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.


Maximum wiring flexibility with built-in high-performance crossover technology. The dual-voice-coil Sub100, with built-in low-pass filters and Sat300, with built-in high-pass filter, can be connected directly to its own amplifier channels for independent volume control.  An easy two-channel connection can be made by connecting the three-speaker sub/sat system to your two-channel amplifier.

Bass Performance

Capacitive Coupling Technology is an advanced signal-blocking technology that determines exactly where a small speaker usually skimps on bass output. Special circuitry then compensates by boosting response in this critical frequency range. More bass response means a wider dynamic range with more musical realism.

Junction Box

The included waterproof IP68 rated junction box easily connects other outdoor speakers and is approved for in-ground use.  

Aluminium Grille

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

Tweeter Performance

Flying bridge-mounted tweeter never gets in the way of the woofer, for smooth, realistic sound in a compact housing.

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.

Exclusive shock absorbing gasket on Sat300 withstands blows from weed whackers, mowers and other lawn equipment – plus, the metal security plate foils thieves and keeps Sat300s planted safely in your garden.


Atrium Sat 300 withstands years of weather with a mineral-filled polypropylene housing, 1mm aluminium grille & stainless steel hardware. These speakers live outside year-round, with permanent colour impregnation and all-weather waterproofing and a 5-year warranty.  

Designed to Blend In

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