i just bout a new RSW-10D, and when you turn the volume up ( nothing connected) it makes a light thumping sound as the volume increasses, and even when you decreass the volume. Yuo cannot hear it below -13, but if you gently touch the rear woofer you can feel a slight bump. Is this normal for this unit to do this, has this problem been noted before?
I am completly new and have not had time to check the search feature, ( so don't kill me yet!)....any help would be appriciated. I just don't know if I should be taking it back tomorow or not............
