A crossover divides the audio signal into different frequency ranges, directing each range to the appropriate driver. For example, a woofer handles low frequencies, while a tweeter handles high frequencies. This ensures that each driver only processes the frequencies it is designed for, improving overall sound quality and preventing distortion to the speakers.
The crossover points that are built into the Forty Eighty and Forty Sixty speakers are as follows...
Forty Sixty – 2kHz
Forty Eighty – 1.6kHz
