[QUOTE="KenM, post: 24658, member: 639"] It's very easy to drive a weaker amplifier into clipping which is essentially like applying DC to a speaker. This causes the cone to move to maximum excursion and subsequently the coil moves out of the magnet, which also acts as a heatsink, the coil expands due to the heat generated (like a bar heater) and cannot fit neatly back into the small gap in the magnet. Continued oscillation of the cone causes the horrible grating noise as the coil scrapes against the metal of the magnet. [/QUOTE]
