## Overview

The NHT O2-ARC is a high-performance 2-way outdoor loudspeaker featuring a 6.5-inch woofer and fluid-cooled 1-inch silk dome tweeter housed in an Anti-Resonance Casting enclosure. Designed for durability, it resists UV rays and moisture, minimizing vibration and cabinet noise for pristine sound quality. Sold individually with a mounting bracket, it’s available in matte black or white finishes, making it the perfect blend of rugged reliability and refined style for outdoor audio enthusiasts.

## Description

The NHT O2-ARC is a unique, high-performance outdoor loudspeaker like no other. Sold as singles, the O2-ARC is not only weather (UV) and moisture resistant, it is specifically tuned to sound just right out there in nature where there are no walls except the one the speaker is nailed to. The O2-ARC includes a time-tested 1-inch treated silk dome, fluid-cooled, UV-treated tweeter that is working together with a robust 6.5-inch midrange-woofer mounted in a traditional NHT sealed box system. The O2-ARC enclosure features NHT's newest material technology: Anti-Resonant Casting or ARC. The ARC enclosure provides unprecedented strength and several lifetimes of durability while it acoustically kills the vibrations of the box itself to inaudible levels. The O2-ARC is available in white or black matte finish and include the mounting bracket.

Review: I was searching for some budget bookshelf speakers to go with KEF Q100s for ATMOS purposes. I tried the NHT SuperZero 2.1s but did not like their low end. I did like the NHT sound so when I noticed how heavy these are as outdoor speakers, I decided to order them. They are rock solid and weigh almost as much as the KEF Q100s. That is definitely a plus as most outdoor speakers are lighter and might suffer from hull noise when played at above moderate volume. Compared with the KEF Q100s, these speakers actually have a similar frequency response in my room. Because they are outdoor speakers, they are inherently much easier to hang than regular bookshelf speakers. Listening tests reveal that they are not as forward as the KEF Q100s and are slightly veiled. In my room these speakers extend down to at least 60Hz which are more than adequate to use as regular bookshelves. These speakers are natural with slight elevated highs. I measured them sideways and found them to have an excellent listening window. The SQ is comparable to the best $500 bookshelf speakers out there and are excellent to use as surrounds and ATMOS speakers. Needless to say, they can do very well outdoors.
Review: Bought one of these speakers to replace another outdoor speaker that gave out. So far so good. Nice and clear. The speakers are really nice looking as well. Speakers are not small so expect them to take up some space.

### ⭐⭐⭐⭐⭐ Review
*by D***S on 5 June 2020*

Replaced a pair of Yamaha (AW150?) speakers - no comparison. Excellent sound from these and the construction is first rate. As full disclosure I'm a long time NHT fan. I still have my 2.5i's from the late 90s and have at least 4 pairs through out the house. These speakers share the NHT sound traits: very neutral, you hear the source material as is. These speakers don't boost the bass or blast the treble. They are musical and mellow. Never harsh, never fatiquing but still quite revealing. NHT tend to be power hungry but these have pretty decent sensitivity. I'm running them with an NAD C740 (35wpc) and there's plenty of power. Plenty of detail at low and mid-low volumes. If you want a great sounding, non-fatiguing outdoor speaker I highly recommend.
