That's listener fatigue. It's a temporary form of tinitis, and is what you'll get anytime you listen to something loudly for a period of time. You can also get it when rising in a convertable, motorcycle or even when your windows are just turned down.
There's nothing wrong with the speakers, they're just capable of playing louder than you're used to, probably mostly during the peaks (like explosions and stuff).
