I use that test at least once a month. Never ruined anything and it showed me a few leaky input caps on occasion.

Using a drum kit can be very confusing. I'd sooner adapt Karbo's solution, putting a very low tone on bothe speakers and comparing woofer displacement while the speakers are next to one another.
