Exactly how a bad speaker sounds too (voice coil warped and dragging), if you slightly and gently push the cone out from behind, you feel if the coil is dragging.

Also a speaker out of phase will sound like sh-t too (no bottom, brassy/scratchy like treble). You can test speaker phasing with a 9 volt battery, momentarily place the battery terminals across the speaker terminal (note battery polarity to speaker), the the cone will push in or out depending on batteries polarity to the speaker, you want all speakers to move in the same direction (with the battery to speaker polarity matched).

You'll be amazed how many people miss this. I've picked up some pretty cherry 4x12 speaker cabinets cheap because a speaker was miss wired!
