Speaker Testing Option 1: Connect a 9 Volt battery to the leads of the speaker, positive lead to positive battery end and negative lead to negative battery end. If a pulse is generated in the speaker then the speaker is still functioning properly. This same practice would apply to the tweeter speaker as well.
