I'm looking for recommendations for a tone generator or frequency generator application, preferably free or low cost if a good one is available, and also an external speaker system or subwoofer capable of low frequency reproduction. Application will be for determining resonant frequencies of assemblies for musical instruments and use in biofeedback setup.
