Just because you live in an apartment, it doesn't mean that you can't get good quality speakers for your setup. Buy in pieces as Crackinheadz suggested and just hold off on the subwoofer until the very end. The subwoofer is what creates the biggest disturbance for neighbours. A very good quality speaker can still be controlled with volume... as can a subwoofer. However, with a good subwoofer, you will constantly be turning it up a bit more everytime you use it until you get yourself into trouble.

Buy good quality for the long haul! Otherwise, you'll just end up spending twice or three times the amount in the long run.
