This is for all you movie buffs! The thought of having a 5.1 surround sound system in a dorm may sound crazy, and it'll definitely require a cooperative roommate, but this set makes it manageable.
Not only are the speakers relatively small (small is code for dorm-friendly), but the back channel speakers can be connected to the subwoofer. Under normal circumstances, that's a nice perk; in a dorm, it's a lifesaver, because it won't require you to string wires all over the admittedly small space.
