![]() They’re usually used for smaller speakers like with tweeters, 2-way coaxial speakers, and component speaker systems because they’re relatively affordable in those situations. “Passive” crossovers are those that use inductor and capacitors, without a power source, to filter out sounds you don’t want to reach speakers. The signal output of an electronic crossover has to be amplified, unlike speaker (passive) crossovers that you connect between an amp and speakers. Unlike passive crossovers, they do require power to work and change the signal, hence the name “active.”Īctive crossovers work with a line-level (RCA) signal either before an amp’s RCA inputs (in add-on external crossovers you can buy) or inside the amp. They offer a lot of benefits (especially their compact size) and can be designed to allow you to choose between using no crossover, a high-pass, or a low-pass easily. Most amps today include what you’ll need already.Īctive crossovers use electrical components such as transistor-based chips called op-amps (operational amplifiers) to behave the same way as their much bigger and much less efficient speaker crossover counterparts. Some offer a few more options, but unlike years gone by, they’re less and less important these days. These are basically the same as the electronic crossovers built into many amps you can buy today. Digital (software) crossovers – they work with sound in the digital music domainĪn example of an external (add-on) electronic (active) 2-way crossover.Passive (speaker) crossovers – work in the amplified speaker path after an amplifier.Active (electronic) crossovers – work in the signal path (line-level signals).What are the 3 types of crossovers in car audio? Simple speaker crossovers can also be added inline with speakers to block lower-end bass as well. In car audio, the most common speaker crossovers are used in 2-way coaxial and component speakers. In fact, you’ll almost never find a good-sounding speaker system that isn’t using one or more types of crossovers that’s how important they are for great sound.Ī crossover (audio crossover) is an electrical or electronic component circuit made up of parts that react to certain frequencies and designed to eliminate unwanted ranges of sound from reaching speakers.Ĭrossovers allow a desired range of sound to pass unaltered and effectively block ranges of sound past a limit called the cutoff frequency.Ī crossover circuit can be used for only one single speaker channel or combined with another to separate and direct sound the best speakers suited to produce it. When we think about musical signals we don’t always realize the important things going on behind the scenes. One reason why crossovers are so helpful there is that we can use them to block terrible-sounding audio frequencies that ordinarily would cause these problems and others, too. That means they leak air badly and can “bottom out” easily if driven hard with bass sounds, for example. To make matters worse, speakers in cars, trucks, and even boats are often mounted in areas where it’s impossible to get great sound because they leak air and don’t form a good enclosure to deliver sound properly unlike home stereo speaker cabinets. Some of the most common speaker sizes installed from the factory or sold for aftermarket use like 3.5″, 4″, and 5.25″ sizes can be terrible for playing bass, resulting in bad sound and ugly distortion. How are crossovers helpful for speakers?Ĭrossovers are very important for car audio as they help us deal with the poor enclosures they’re used in along with the weaknesses that small speakers have. While they sort-of do, in reality, crossovers are filters that greatly reduce the amount of unwanted sound frequencies sent to speakers. People tend to talk about crossovers as if they totally “block” sounds you don’t want to go to your speakers. What does a crossover do?
