I've never had a speaker die on me (Unintentionally Hahaha )
Usually speakers die due to only few factors.
Being Under-powered, Which causes distortion and can cause speaker coil to overheat.
Being Over-Powered, Which again causes the speaker to 'Bottom out' & blow.
Crossover unbalanced, Which implies to most smaller speakers cause bass can also cause distortion if the speakers Frequency response isn't accurately set.
Or, Destroying them Yourself with a sledgehammer.
