Dynamic Balance(R)
Engineered with a dual voice coil, Dynamic Balance(R) aerated polypropylene cone with rubber surround for greater power handling and better efficiency.
This patented technology analyzes the speaker's entire electro-acoustic and mechanical system for improved material selection and more efficient geometry.
Dual Input / Single Input Switch
The Atrium8 SDI has a patented dual input/single input switch. This switch enables the Atrium8 SDI to be used either as a single high-performance stereo loudspeaker, or the left-or-right speaker in a high performance stereo pair.
Stereo speakers love 4-core speaker cable
Because stereo speakers have connections for both left and right channels, running a single 4-core speaker cable is recommended as you only need to run a single cable to each of the stereo speakers. We have 4-core speaker cable available by-the-metre, or by-the-roll!
All Weather Certified and Water Resistant
Built to withstand the worst elements - salt-fog, UV, extreme temps or heavy rains, you name it.
PowerPort Technology
Smoothly transitions air flow from the speaker into your listening area for deep, extended bass impact while minimising turbulence and distortion.
Durable Construction
Aluminium grilles and bracket, with stainless steel and brass hardware means no rust - ever.
Speed Lock Mounting System
The Atrium series feature a quick and easy mounting system. Simply mount the bracket and click the speaker into place, aim it and tighten it down.
