horn? o_o

[icytoast]

On the back of my amp cabinet there's a button for Horn and you can either turn it on or off.
What is the horn and what does it do?
I'm really new to amps and all this hardware type stuff :S

Horn is a method for speaker loading, that is, a way to increase the output and change the dispersion. It's often used on tweeters in bass cabs that have tweeters. That knob controls your highs. Try slapping and popping and turn it on and off.
