Note that the OoO is a passive speaker and requires an amplifier or receiver to play sound. It cannot play sound directly from a turntable, phone, or TV without an amplifier. Build a great sound system for listening to music or watching movies even when space is limited! The compact Micca OoO speaker sounds much larger than it looks, giving listeners a fully immersive experience with its dynamic and extended sound signature. Its slim shape can be used horizontally as a center channel speaker, vertically as bookshelf speakers, or use with optional wall mounting brackets as surround sound speakers. This flexibility allows a sound system to be built using one or more units of the Micca OoO in phases, with the ability to move the OoO to different locations as needed. 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. Try one, two, three, five, seven, or nine today!
