NHT SuperZero 2.1 Mini-Monitor Speaker (Single, Gloss Black) The SuperZero 2.1 is a true high-end mini-monitor that builds on the merits of its predecessors through the addition of a 2nd order crossover and a newly revised woofer The SuperZero 2.1 is small speaker, at just 9" tall x 5" wide x 5.5" deep, that achieves its lifelike mid-range and high frequencies through acoustic suspension technology This compact, well-braced cabinet coated with a beautiful black gloss laminate is designed to be inherently strong and stout in order to avoid the unwanted vibrations that afflict the mid-range performance of other speakers on the market These small differences significantly lower distortion, improve power handling, and make the SuperZero 2.1 sound much bigger than its size With easy wall/ceiling mounting options available, the SuperZero 2.1 complements the SS 10 subwoofer perfectly in creating an affordable yet high-end stereo or surround sound system
