Good thing you did not buy them.... The speakers are no good or have crappy speakers....
what they do is tell you they have extra speakers or some their customer decided not to use and they want to get rid of them or sell them for cheap. Then they will want to show you the speakers. They will have some realy nice speakers (bose or something) that you can look at. Then once you agree to buy them.. they will then sale you the "boxed ones" which are generally trash speakers or broken ones.
