I really don't have enough desktop space for more than two speakers and evidently I must be alone. I'm shopping for a 2.1 system for my computer and all I can find at department stores are Bose Companion 3's for 250.00 and a Klipsh model for 150.00. There is another brand of Bose computer speaker calle Media Mates without a sub for 99.00. I'm leaning towards these because of the price factor. Is it possible to buy a 5.1 system and just use two of the speakers? If this is possible I might just do that instead.
