The O2-ARC is a unique, high-performance outdoor loudspeaker that is specifically tuned to sound in-line with its surroundings. Not only is the O2-ARC weather (UV) and moisture resistant, it includes a mounting bracket that is strong enough to the speaker horizontally, vertically or anywhere in-between. Over the years we have learned that our Outdoor speakers have earned a reputation venues ranging from bars to health club. Fortunately, it’s a sound one because the O2-ARC is not only appealing, but also highly durable. 

The O2-ARC's qualities stem from its fine materials and solid design. The O2-ARC contains a time tested UV treated 1” treated silk dome, fluid cooled tweeter with a robust 6.5” midrange-woofer mounted in the standard NHT acoustic suspension (sealed box) design. It's cabinet, however, features our newest materials technology - Anti-Resonant Casting or ARC. In particular, the ARC enclosure provides unprecedented strength and durability while simultaneously minimizing undesirable box vibrations to inaudible levels. A new, flush magnetic front grill further achieves this effect while protecting the drivers from the elements. In short, the no other outdoor speaker can best the O2-ARC.

The O2-ARC is available in matte white or black finish and includes a mounting bracket as well.

Still use them every summer, they are definitely waterproof, made the mistake of leaving them out all winter, still sounded great in the spring! We eventually bought three more pairs. I have tried them both ways, v. or h., liked verticle the best.
