Logitech (http://www.logitech.com) has unveiled the THX Certified Logitech Speaker System Z623. With this 2.1 system, you’ll hear and feel immersive audio from 200 watts (RMS) of power whether you’re connecting the speakers to a computer or a TV.

Logitech includes all the inputs and cables you need to get great sound from up to three audio devices, according to Mark Schneider, vice president and general manager of Logitech’s audio business unit. There are RCA and 3.5 mm inputs, in addition to the built-in headphone jack. Integrated controls on the right speaker satellite let you dial the volume and bass up or down to customize your listening experience.

The Logitech Z623 speakers are THX Certified. To qualify for THX certification, the two-satellite-and-subwoofer Z623 speaker system has to meet strict performance standards, Schneider says. The Logitech Speaker System Z623 is expected to be available in the U.S. and Europe in September for a suggested retail price of $149.99.
