User manual POLK AUDIO AB555

[. . . ] Loudspeakers can be damaged when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce. Operation at this level can result in very high levels of audible distortion originating in the amplifier, which can add a harsh, gritty sound to your listening material. If you hear distortion--turn the volume down or risk damaging your speakers. You can damage just about any speaker, regardless of power rating, if you drive an amplifier to or beyond the point of distortion. [. . . ] If you choose to build your own enclosure, be sure to build it well. Make certain it's properly sealed and airtight for maximum bass performance.

Make certain your electronic equipment is operating correctly by hooking up another speaker to the speaker output.
