Some crossovers also come with an equalizer function. In most cases, it enables controlling the relative volume of each frequency band, and of course the frequency steps themselves. It goes between the receiver and the amplifier and operates with lower-level, non-amplified signals. These crossovers are usually factory-implemented and are often less accurate, resulting in a sound of a lesser quality.Īn active crossover requires an additional power source and is a bit more complicated to install. They are placed between the amplifier and the speakers or sub and, as such, take an already amplified signal to the right driver. They limit control by allowing the tweeter volume to be adjusted relative to the woofer volume. Passive crossovers don’t require power and offer limited control over the volume of each channel. There are two crossover types–active and passive. The “box” on the right is the passive crossover that comes with Hertz High Energy components. In the worst case scenario, some frequencies could disappear completely with others claiming their place. Mid and bass notes would clash together in the woofers, and tweeters would waste energy playing mid-range notes. If these frequencies aren’t directed properly, then speakers will try to play sounds they aren’t meant to play. Every full-range speaker has a crossover network inside. Tweeters, woofers and subs should get high, mid and low frequencies respectively. Why Do You Need A Crossover?Įvery audio system, including the one in your car, needs a crossover to direct sound to the correct driver. It’s easy to imagine by picturing it as a crossroads with three paths to take and the crossover serving as the sign that points each band of frequencies to its destination. So, for example, a single input signal can be separated into bands of low-, high-, and mid- range frequencies. The Audison bitTen processor includes a very high end active crossoverĬrossovers are electronics devices that convert a single audio input signal into two or three signals by dividing the signal into bands based on frequencies.
