I second what Eldartford wrote. Under normal use it shouldn't be a problem, but under some unique circumstances it could damage your speaker.
A few examples:
- an interconnect is plugged/unplugged with the amp on
- you drop your tonearm and the stylus skates across the record
- your preamp doesn't buffer the tape outputs and you create a feedback loop
- you momentarily lose power and as your system re-powers one of your components generates a turn on pulse
You get the idea. It's not likely, but it's not out of the question.
