Last night Logitech announced four new multimedia speakers that may not have docks for iPods, but they do what speakers should do best – blast your ears off. These four new models include the Logitech Speaker System Z320, Logitech Speaker System Z323, Logitech Speaker System Z520 and the Logitech Speaker System Z523. The sound quality and designs have been improved to make these speakers even more sleek and sound more powerful. The multimedia speaker systems feature 360-degree Sound, or omnidirectional acoustics, meaning that movement of the speakers anywhere in a room or on your desk will not deter the sound but only enhance it or stay the same. You won’t lose any quality if you shove it in the corner of your desk. The Logitech Speaker System Z320 and Logitech Speaker System Z323 will retail for $69.99 and be available in August and September respectively.  The Logitech Speaker System Z523 is expected to be available soon in July and retail for $99.99. The Logitech Speaker System Z520 is also expected sometime in July and will retail for $129.99.
