Single/Dual input switch and dual tweeter array that lets you work the speaker as a single high/performance stereo loudspeaker, or L/R speaker in a high performance stereo pair. It’s time to get that indoor sound you love – all from an outdoor loudspeaker you can put anywhere around your home.

The flagship of the line, the Atrium 8 SDI has a unique, patented single/dual input switch that, combined with its ingenious dual tweeter array, enables you to use it as either a single high performance stereo loudspeaker or the left-or-right speaker in a high performance stereo pair. And you can use it practically anywhere, because the Atrium 8 SDI also has special US military spec waterproofing features, including our patented water-resistant PowerPort® bass venting.

 Atrium Sat300

The 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 while delivering high-performance audio, this is a full-range speaker that can blend into a wide range of landscapes and environments. And it’s designed to pair perfectly with a Sub100 for a real high-performance audio system.

Dynamic Balance® Driver Technology

3 1/2-inch long-throw midrange driver with the 1-inch voice coil, vented pole-piece, rugged butyl rubber surround and composite cone; 3/4-inch composite dome neodymium tweeter.

Power

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.

Tweeter Performance

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

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.

Durable

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.

Safe

Exclusive shock-absorbing gasket 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. Also includes a 1-meter Cl3-rated direct burial pigtail cable to eliminate exposed wiring.

Flexibility

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