Thanks! Some amps, head units, and digital processors/equalizers for car audio offer more crossover options for people who want advanced control – especially if you’re working on a high-end sound system. That’s one reason the built-in low-pass subwoofer crossovers in amps are so great. 60 to 70Hz or so are pretty common crossover frequencies that usually work well. Small … Some will say that you should set the crossover point 10% above that -3dB frequency, but with decent quality components it’s really a matter of taste rather than a hard and fast rule. While they sort-of do, in reality, crossovers are filters that greatly reduce the amount of unwanted sound frequencies sent to speakers. Copyright © 2017-2020 SoundCertified.com. They're poor for treble and a tweeter should be added. And as I mentioned ealier, -12dB per octave (“-12dB/octave”) is very common in car audio. This should be around the 60-70Hz range. We don’t want to block bass found in the lower end of midrange like from the vocals in music (for example, around 100-120Hz or so). Unlike passive crossovers, they do require power to work and change the signal, hence the name “active.”. The signal output of an electronic crossover has to be amplified, unlike speaker (passive) crossovers that you connect between an amp and speakers.

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. 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. 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. “Passive” crossovers are those that use inductor and capacitors, without a power source, to filter out sounds you don’t want to reach speakers. This makes them more complicated but saves spaces & money since it reduces size & the electronics required. Good low-pass frequency range for subwoofer bass & blocking midrange sounds. More great speaker and crossover info to see. 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. If your center speaker can produce 80Hz to 120Hz, then you want your low-pass crossover to be anywhere close to 90Hz. Woofers and many midrange speakers do not perform well above this general range. Un design splendide et une technologie de pointe pour reproduire numériquement la musique que vous aimez avec un son Hi-Fi authentique.. Adjust the crossover frequency control to the lowest setting (this is usually around 50Hz for most amps). I don’t recommend that in most cases. People tend to talk about crossovers as if they totally “block” sounds you don’t want to go to your speakers. An example of an external (add-on) electronic (active) 2-way crossover. Passive speakers aren’t used to block midrange and treble (“highs”) from subwoofers because the size of the inductors needed would be really big – and expensive, too! A crossover can’t fix that problem. The crossover frequency is the sound frequency point at which sounds after that will be greatly reduced, effectively blocking them. We use it as a reference point at which the output to a speaker (or the input to an amplifier, when using active crossovers) is reduced by 3 decibels (-3dB). What are the 3 types of crossovers in car audio? Check out my installation guides and technical info, too! Adjust the crossover frequency control to the lowest setting (this is usually around 50Hz for most amps). These are basically the same as the electronic crossovers built into many amps you can buy today. Most people typically use a car amplifier for one of a few basic systems: For cases #1 and 2, if your amplifier has a built-in crossover option you can use the high pass crossover to block low end bass that small speakers simply can’t produce well, if at all. Conçu autour de l'ensemble de haut-parleurs Uni-Q de 12e génération avec technologie d'absorption des métamatériaux, cette ensemble robuste et compacte est capable de fournir un son détaillé n'importe où dans la pièce. That’s a much more advanced topic and worth its own article, by the way. Find out here. For amplifiers with adjustable crossovers, use the following steps: Similarly, do the following to adjust the subwoofer frequency & crossover: However, I’ve seen many cases where a subwoofer installed in the wrong type of subwoofer enclosure produces bland, poor sound. Note: Not all amplifiers offer an adjustable control. Now that the basics of crossovers are understood, let's cover some good starting points for various system configurations (consult the speaker's manufacturer for more detailed information on their recommended frequency response).
