What is the crossover rate rule? The crossover rate rule is a guideline for selecting the slope of a crossover filter. A common rule is that each octave of frequency difference should correspond to a 6 dB/octave slope. For example, a 12 dB/octave slope might be used for a crossover between drivers that are one octave apart in frequency.

What is a typical crossover rate? A typical crossover rate often ranges from 6 dB/octave (first-order) to 24 dB/octave (fourth-order), depending on the specific audio system and the desired roll-off characteristics.

Do tweeters need a crossover? Yes, tweeters typically require a crossover to protect them from receiving low-frequency signals that could damage them. A crossover directs only the high-frequency signals to the tweeter.

What are the disadvantages of passive crossover? Disadvantages of passive crossovers include power loss (heat generation), limited flexibility in adjusting crossover parameters, and potential phase and impedance issues.

Do I need a crossover if my amp has one? If your amplifier has a built-in crossover, you may still benefit from using an external crossover or additional EQ to fine-tune your audio system, especially in more advanced setups.

What are the disadvantages of active crossovers? Disadvantages of active crossovers include the need for separate amplifiers for each driver, increased complexity in setup, and potentially higher cost due to the need for additional equipment.

Is DSP better than crossover? DSP (Digital Signal Processing) can provide more precise control and flexibility than traditional crossovers. It allows for fine-tuning of crossover frequencies, slopes, and other audio parameters.

What makes a good crossover? A good crossover effectively separates audio signals for different drivers, has adjustable parameters for customization, maintains phase coherence, and minimizes signal loss.

What should my LPF slope be? The slope of your low-pass filter (LPF) should be chosen based on your audio system’s requirements. Common LPF slopes are 12 dB/octave, 24 dB/octave, and 48 dB/octave.

What should I set my LPF and subsonic to? The settings for your low-pass filter (LPF) and subsonic filter should be chosen based on the specifications of your subwoofer, your main speakers, and room acoustics. Common LPF settings range from 80 Hz to 120 Hz, and subsonic filters are typically set to protect against frequencies below the subwoofer’s capabilities.
