Replying to Compact Speaker Suggestions?

Wondering if anyone has any suggestions for a small "boombox" type speaker to use at my computer. What I'm looking for is something with multiple speakers/a sub all enclosed in one nice tidy unit (I move around a bit). Primary use will be at my desk, and I already have a tiny battery powered speaker for playing music on a phone/tablet when I travel. Because of this, I'm not concerned with this one being battery powered or having Bluetooth. Also trying to keep cost minimal, would like it to be under $100, and while I do want decent quality, this will mostly be for gaming/listening to music, and I have nice headphones already, so I would definitely consider budget options.
