If your full range speakers are the head of your PA system, then the Subwoofers would be the heart. Subwoofers generate low end frequencies that can be felt and add presence and fullness to your sound. A good PA should have a balance of high, mid and low frequencies without one dominating the other. Whether you're a DJ, 80's cover band or a massive touring rock act, subwoofers are an essential part of putting on a good show.
