Its the same noises as in analog-equipment. For ruining the speakers you need 
a square wave, the longer the square, the better. The involved 
high-frequencies might be to much for the high-freq-speaker as normaly the 
signal-amount in this part isn't the same as in the lower parts so 
speaker-manufactures don't have to make them to powerfull to get the label 
200W sticked on them.

And a real constant value outputted from your self-made-synthesizers will kill 
the bass-box...

How to do that in analog? Feedbacks and plugging a battery on the box or 
getting a voltage-shift into your equipment...

If this is not correct, please correct me,

Arnold
