What crossover setting should I use for my car speakers and subwoofer?

Choosing the right crossover point depends on your speakers, subwoofer, amplifier, DSP, enclosure design, vehicle acoustics and listening preferences. There is no single setting that suits every car audio system, but the goal is always the same: each speaker should only play the frequencies it is designed to handle.

For subwoofers, many systems are tuned with a low-pass crossover somewhere around the lower bass range so the subwoofer focuses on deep bass rather than vocals or higher-frequency sounds. If the crossover is set too high, the bass may become easier to locate from the rear of the vehicle, which can make the system sound less natural.

For door speakers or component speakers, a high-pass crossover is often used to reduce deep bass frequencies that may cause distortion or unnecessary speaker movement. This can help improve clarity, protect the speakers and allow the subwoofer to handle the deeper bass.

The ideal crossover point depends on the size and performance of the speakers. Smaller speakers may need a higher crossover point, while stronger midbass drivers may be able to play lower. Subwoofer size, enclosure type and amplifier power also affect the best setting.

Crossover settings should not be treated as tone controls. They are designed to divide frequencies correctly between speakers and subwoofers. Equalisation, DSP tuning and level adjustment are separate tools used to refine the final sound.

For the best result, speak with your nearest Focal Authorised Australian Dealer. A professional dealer can set the correct crossover points for your Focal speakers and subwoofer, tune the system properly and make sure the bass blends cleanly with the rest of your car audio system.
