What are Active Crossovers?

Active crossovers need electricity to filter the signal. Moreover, they require ground connections as well to remove unwanted noises. That being said, the active quality in their performance allows the user further flexibility and fine-tuning control over the music.

What are Passive Crossovers?

Passive crossovers perform a similar task to active crossovers but with two very different qualities: they don’t need the power to operate and they can’t offer so many audio tuning capabilities. On the good part, they are easier to install, on the not-so-good part, they are, mostly, one-trick ponies.
