IO studio monitor is an active 2-way appliance equipped with two speakers (tweeter and woofer) and two independent power amplifiers for each speaker fixed on the back plate of the monitor enclosure, as well as with an appropriate set of precise regulators, signalizes, inputs and security devices.

Both speakers applied in IO are produced by well known company SEAS from Norway. The woofer is a construction meeting the APS strict requirements. Like its bigger brother IO monitor is offered in two versions: with a titanium or a fabric dome tweeter.

The monitor has been closed in the bass reflex enclosure with front ventilation. The cabinet design combining small dimensions with thick front and side walls ensures extremely rigid base for speakers and electronic module mounted in it. The edges of the monitor enclosure have been rounded to reduce reflections and to improve the quality of produced sound. The inner wall of the enclosure that completely separates the electronic module from the speaker chamber constitutes at the same time an additional reinforcement of the enclosure eliminating minute oscillations of the monitor enclosure side walls.

Black semi-gloss lacquer is the standard finish of IO.
