A speaker generally consists of two-way or three-way speakers. This defines how many types of drivers are installed. Two-way speakers usually have one woofer and one tweeter; three-way speakers come with an additional midrange-woofer. A crossover makes sure that the right frequency arrives at the right driver. A two-way crossover is a combination of a low-pass filter (LPF) and a high-pass filter (HPF) – high frequencies via an HPF for the tweeter, low frequencies via an LPF for the woofer and frequencies in between to the midrange woofer. Here at SoundImports, you can buy two-way, three-way, HPF's, LPF's and many more passive crossovers from brands such as Dayton Audio and Monacor!
What is the difference between active and passive crossovers?
The difference between an active and a passive crossover is that an active crossover requires an external power supply while a passive crossover does not. This makes an active crossover less prevalent since the additional power components make active crossovers more expensive.
What is an assembled passive crossover?
As the name already suggests, an assembled passive crossover is a passive crossover that is pre-assembled. The advantage of this is that all components assembled are already matched up to one another. This saved time and, sometimes, frustration!
Is there something I should pay attention to when purchasing an assembled passive crossover?
Yes, there is. First of all, you need to decide on the type of passive crossover you want or need. Besides, you may check the required frequency range and required Ohms. The crossover board's size is relevant since most crossover board get placed inside the speaker after the case got assembled. Therefore, you should make sure that the chosen assembled passive crossover board is not larger than the woofer cut-out diameter in the case.
