Since they don’t require two types of amplifiers, they are cheaper than active crossovers. They work well in cases with high current and high voltage. Passive crossovers are used after the amplifier rather than on the input. This is why people usually install 2-way crossovers for both the tweeter and woofer. These crossovers need power amplifiers on every output band. They are used for amplifiers inputs to curb the noise that can be created when signals are amplified. They have active components in their filters, and the most common type is the op-amp. What Is an Active CrossoverĪctive audio crossovers are installed before the amplifier. The latter is used for monitor speakers, PA speakers, subwoofer The former is used for keyboards or bass amplifiers andĮnclosures. Need a proper sound system, you will need two things: crossovers and a sound If you’re planning on going for professional audio where you Crossovers are generally used in car speaker systems, but they can also be used for other sound systems. The signal will be routed accordingly to the tweeter or woofer of the PA system cabinet, ensuring the highest quality sound. The crossover will be used to split all the different frequencies from high to low. Whether you’re listening to a live band on stage or playing recorded music from a CD, you will need an audio crossover installed to make the sound clear. It contains woofers for mid to low frequencies, as well as a tweeter for high range frequencies. Since every speaker is designed to operate on a different frequency band, you will need an audio crossover system to separate the frequencies accordingly.įor example, let’s say you have a PA system cabinet. Most sound systems or multi-frequency speaker systems have multiple different sized speakers. This is because the driver (speaker) can’t handle all frequencies from high to low. If you pass the entire audio range through, it will cause distortion and a strange relative volume. You can split the full range audio signal into two (bass and treble) or three (bass, mid range and treble) bands, which will greatly improve the quality of the sound.Īudio crossovers are mostly used when a speaker can’t cover the entire audio spectrum, ie a subwoofer (bass) or tweeter (treble) speaker. The crossover breaks the signals into different audio frequencies and sends them to the right driver (speaker). There are many different applications of this electronic filter. The crossover is essential for any sound system because it compensates for the natural electrical components of the drivers in the sound system. Basically, it acts as a traffic police cop it allows some frequencies to travel through and stops others so that there isn’t an accident on the road or distorted sounds in speaker land. The audio crossover plays a critical role in a sound system since it stops the signal’s full range from reaching the speaker. The crossover is designed to stop certain frequencies from traveling through to the speaker/output. If the audio being sent to a bass speaker did not pass through a crossover for bass speakers to remove the high treble frequencies then the bass speaker would play distorted treble sounds as it has not been designed to play high frequencies. The same is true for a large bass speaker or subwoofer. If the low frequencies were not removed the tweeter would play distorted sounds as it doesn’t have the capability to play low (bass) sounds. Inappropriate frequencies are removed to ensure the speaker does not play distorted sounds.įor example, low (bass) frequencies will be removed/filtered from the music (audio signals) being sent to a tweeter, because tweeters are designed only to play high (treble) frequencies. Put simply, a crossover is an electronic device which is wired between the amplifier and the car speaker to ensure bass frequencies are sent to bass speakers and treble frequencies are sent to treble speakers. Here is a simple guide that will tell you more aboutĬrossovers, as well as the different types of crossovers. You use it incorrectly, it can negatively impact the overall sound quality of Well, simply put, yes! The crossover is an essential item for sound systems. But what does it mean? Is it even necessary? If you’re new to speaker systems, you’ve probably heard the
