The OoO’s versatility is the result of its neutral sound signature, characterized by a smooth and even tonal balance throughout its output range. Designed to be accurate and transparent, the OoO renders an expansive and well focused soundstage by minimizing unwanted dispersion. Despite its compact size, the OoO delivers punchy bass response that is satisfying enough to use on its own, but should be paired with a subwoofer for especially demanding music or movie soundtracks.

Each OoO speaker holds two 3-inch square frame woofers in a ported enclosure, achieving usable bass extension down to 60Hz. The woofer’s woven kevlar diaphragm has been carefully designed to produce little midrange distortion and a naturally steep high frequency roll-off. The tweeter is based on Micca’s popular 0.75-inch silk dome design, using a high efficiency neodymium magnet and small diameter bezel for tight driver spacing.

A relatively simple yet effective crossover handles the frequency transition between the drivers. A 6dB/Octave low-pass circuit is used on the woofers while a 12dB/Octave high-pass circuit with level matching is used on the tweeter. The crossover slopes and points were carefully chosen to mesh with the drivers’ natural characteristics to produce a flat and coherent final acoustic response. The OoO sound best with its cloth grill in place.
