If you just getting into recording, just use what you have until you can afford to move more recording equipment into the equation. Yes you can use Good Stereo speakers, but the results will not translate all that great. The cost of professional monitors have dropped pretty low, you can get a pair for around $200 bucks, which is far less than some home stereo speakers. The problems of using stereo speakers which have a dynamic frequency response will reveal themselves soon enough. Do what ya gotta do to get it done.
