Went to Goodwill today and found another set of Apple Pro Speakers. Ironically, I bought a set off of Amazon for $20 shipped a week prior.
These were $3. The cord length is different, but otherwise work perfectly.
There were two versions of the Pro Speakers. One was intended for use with G4 towers(Digital Audio and later) and has a relatively long cord so that the speakers will comfortably sit on your desk while the tower is on the floor. The other is meant for the iMac G4(I think they shipped with the iMacs) and has a much shorter cord with the idea being it sits right next to the iMac.
