Frag Maniac, the Creative Gigaworks T20 have a good bass? I wanted one 2.1 for my bedroom because the subwoofer, i really like a good bass ^^''
Here's the thing with deep bass frequencies, they are NOT directional and therefore bass speakers or speakers that produce deep bass via tuned bass ports do not have to be "aimed" like midrange and high frequency speakers do. The only possible trade off will be whether you can manage to place the T20s near or in corners, which is not usually an option with desktop speakers. Though deep bass is not directional, it DOES benefit from corner positioning.
You may be skeptical about the T20's claim of 40Hz bass, but consider this. Bose for years has been producing small speakers and tuned bass ports that mimic the sound of a full sized subwoofer. As I said earlier though, you will not likely get living room filling volume for movie and game explosions a dedicated sub would provide, but then again many 2.1 sets in the T20's price range wouldn't either, or at the very least wear out quickly if you try to get that from them.
