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.
