Description

This passive subwoofer filter from QTX is built for Hi-Fi and PA loudspeaker systems where you need to send low frequencies to the right driver. It works as a low-pass crossover, letting bass through while rolling off higher frequencies so your subwoofer only handles the content it is meant to reproduce. Being passive, it sits inline in the speaker circuit and needs no external power.

The crossover frequency is fixed at 120Hz, with a damping factor of 12dB per octave. That slope gives a steady roll-off above the crossover point, which keeps mid and high frequencies out of the sub and helps the whole system sound cleaner. It is rated at 4 Ohms and handles up to 600W, so it suits a good range of loudspeaker builds and cabinet projects.

Connections are made by solder terminals, which give you a solid, permanent join once the filter is wired into your build. This is a component part rather than a finished unit, so it is aimed at anyone assembling or repairing a speaker system. If you are matching it to a driver, check that the impedance and power figures line up with your subwoofer before you fit it.
