Active Crossover Calculator

An active crossover is an electronic device used in audio systems to split an incoming audio signal into different frequency bands before amplification. Unlike passive crossovers, active crossovers use electronic components and require power. They offer more precise control over signal processing and are often favored for multi-driver speaker setups in professional audio and high-end home audio systems.

FAQs

What should I set my crossover frequency at? The ideal crossover frequency depends on your specific audio setup and speaker characteristics. A common starting point is around 80Hz, but it can vary. You should experiment and adjust it based on the performance of your speakers and subwoofer.

What is an active crossover? An active crossover is an electronic circuit that splits an audio signal into different frequency bands before amplification. It is typically used before amplifiers to send the appropriate frequencies to different speakers or drivers, providing more precise control over the audio output.

What should I set my subwoofer crossover to? The subwoofer crossover frequency is typically set between 80Hz and 120Hz, but again, it depends on your specific setup. Start at around 80Hz and adjust it based on how well it blends with your main speakers.

What is the formula for passive crossover? The formula for a passive crossover network involves calculations for the values of capacitors, inductors, and resistors to create the desired frequency response. It’s a complex calculation and varies depending on the crossover type (e.g., first-order, second-order, etc.). Online calculators or dedicated software are often used for this purpose.

Should crossover be 80Hz or 100Hz? Both 80Hz and 100Hz can work well as crossover frequencies, but it depends on your specific speakers and subwoofer. 80Hz is a common starting point and often provides good results, but if your speakers and room acoustics favor 100Hz, that can be a suitable choice too.

Is a higher or lower crossover frequency better? There is no one-size-fits-all answer. A higher crossover frequency sends more midrange frequencies to the subwoofer, which can be good for blending with small speakers. A lower crossover frequency sends more bass to the subwoofer, which can be better for larger speakers. The “better” choice depends on your system and listening preferences.

Which is better active or passive crossover? Active crossovers are often preferred for their flexibility and precision, as they are adjustable and provide better control over the audio signal. Passive crossovers are simpler but can introduce some signal loss.
