There never was a 'second rapping'. I don't think the delivery man wanted to see my face when I saw the condition of the box. I found it in the driveway. The bottom of the box had been ripped open and taped closed and there was a big chunk taken out of the top of it. It looked like they let loose the tazmanian devil on my M60 part deux. Luckily, there wasn't any damage to it. I just love these speakers. They rock. I've been spending the last 2 hours popping in one cd after another.
