What is a Crossover?
Crossovers are not the most glamorous or talked about gear in live sound, but they are an integral part of the signal chain. Also known as frequency divider networks, these devices filter and route the signal based on frequency. Without a crossover, the same signal gets fed to each driver in the system. Imagine the tweeter, mids, and sub all playing the same song reading the same balance of frequencies. The poor tweeter’s exerting just as much energy into sound waves exponentially larger than itself as its favorite treble tones, therefore reducing the overall output or worse. And what about the sub, as graceful as a hippo, muddying the high end?
