I just got my DLS today...I think there is a problem with it thought. During stretched bass scenes i hear a boboling noise like and it sounds as if its bottoming out. i have the crossover set to about 75 and the volume about half. I have no adjustment on my reciever except just a -10 to 10 db adjustment. I dont know what to do, im really disapointed and i hope im doing somthing wrong. anyone know what the problem migh be?
