Unless you were driving the speakers very loud and with an amplifier that was too low powered to control the drivers, I would say no.
I don't know who's disc you were using, but the Purist Audio disc has been my favorite break in device for many years. I have used it on my own system and loaned it to friends with all kinds of speakers ( Vandersteen, B&W, JM Labs ) with no problem.
