I heard these Logitech speakers on display at Compusmart here in town for $250 Canadian you get 4.1 plus a powerful sub. Total power 400W RMS approx... loved the sound. Is there an equivalent 2.1 with the same design of speakers and sub? If not Logitech, can anyone recommend a good set of 2.1 speakers for my computer? Max I'm looking to spend is about $120 Canadian. Thanks.
