NWin is a software package designed specifically for production testing loudspeakers and other audio transducers.  It can make sophisticated pass or fail decisions and report on production performance.  The user creates the tests they need and then combines them to create a test sequence.  You will need a PC fitted with a sound card, a microphone (possibly with a pre-amp), a power amp if you're doing this seriously, and a loudspeaker ... to test.
