AFAIK even DC amplifiers like the Harmon Kardon have 
coupling capacitors on the inputs to prevent damage from 
this. The amplifier is only DC coupled internally, so 
shouldn't be a problem.

OTOH if you have a lower quality system, I would not be 
surprised if you could force parasitic oscillation of the 
amplifiers with overdiven high frequency, burning them out. 
I think tweeters are probably at the biggest risk.
