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.

Good enough


I would never have thought it possible for any sub $300 speaker to scale as they do. You end up with a speaker that will match and better other recognized and well-respected makers in their thousands. My Kef 101 and LS50's with the B12d are both still my reference though they differ in strengths. Great bargain!

Update -- Almost three weeks now. Still very happy about the speakers. Next update's will be if there's any issue I'll experience with it.

so happy with these


Mounted these on the patio two years ago and they're awesome.  No shortcuts in the sound.  They can cut through wind and traffic noise in the afternoon, and then at 1am wooden music sounds exquisite at lower volumes.  I've heard lots of outdoor speakers that can go loud, and the O2-ARC's can also, but they sound superior to any outdoor speaker I've heard at any volume.

The first winter I brought them in, but have left them mounted the past two.
