Choosing the Right Low Pass Frequency

For peak system performance, selecting the correct frequency is essential. If you are undecided between two frequency values for your low pass crossover, the professional recommendation is to err on the side of the lower value.

Selecting the lower frequency provides a tighter safety margin, ensuring your subwoofers only reproduce the deep bass frequencies they are designed to handle. This results in a more refined output, improved signal clarity, and superior protection for your subwoofers and amplifiers.
