How to Wire Speaker Crossovers
Whether you’re building a stereo system or just want to improve your existing one, speaker crossovers are a critical component. These devices allow you to separate high, mid, and low frequencies for a more balanced sound.
Basically, speaker crossovers are an audio circuit that uses inductors and capacitors to isolate speakers’ inputs and outputs from each other. They work by reducing the AC resistance of the input and increasing that of the output, which helps to reduce sound pressure on the driver.
When a crossover is installed, it can also prevent speakers from getting out of phase with each other. This can cause distorted or out-of-range bass, which is not pleasant to listen to.
There are two main types of speaker crossovers: passive and active. Passive crossovers connect between the amplifier and the speakers and can be used with a wide range of speaker impedances.
They are the most common type of crossover and can be found on most cars and homes that have audio systems. They look like little cylinders with RCA connectors on each end and plug into your amp’s inputs.
These are usually a good choice for car systems that have a wide range of speakers and need to optimize the quality of their sound. The downside is that they are often expensive to install and require professional installation, but they can be a very effective way to enhance your sound.
Some in-line speaker crossovers, such as those offered by Teufel Audio, are very inexpensive and can sharpen the sound of your audio system. They also help your amplifiers to save energy by not amplifying high frequencies that aren’t needed, such as those from the subwoofer.
How to Wire a Crossover
To wire a crossover, first make sure you have the right speaker wires and connectors for your speakers. This will ensure that you get a good match and the crossover works properly.
Next, insert the correct speaker wire into each jack on your crossover. Typically, the jacks are marked with the speaker type and polarity to indicate which speaker you’re connecting. You may need to wiggle the wires in the jack to be sure they’re oriented correctly.
Once you have the correct jacks and the wires attached, plug the crossover into the preamplifier or receiver using the appropriate cables (typically RCA or speaker wire for a home stereo system). Then plug each output on the crossover into an appropriate amplifier that will drive the specific type of speaker.
When installing the crossover, remember to ground it properly. This is essential to preventing interference from the power supply and other components.
If you don’t know how to ground a crossover, it can have a serious impact on the quality of your sound. A good grounding system should be able to handle all the power your crossover needs and provide adequate protection against electrical surges.
The most important thing to remember is that a speaker’s impedance changes with frequency, so you need to use the exact values for your speakers to achieve optimal performance. These values should be on the speaker’s specification sheet and will vary depending on the model of speaker you have.
