running my new lmIII thru schroeder 21012 L and it sounds as if 0ne of the 10s is making a fluttering sound on both cabs.I have been running a b1500 thru 2 of these cabs recently and have not noticed this.It doesnt seem as if the speakers r blown,seems as if the head is pushing them to hard? 500 watt head thru a 4 ohm 1000 watt cab,doesnt make sense to me that it would be doing this.I have the volume up bout quarter of the way.any suggestions?
