Weak subwoofers employ limiters (ie high-pass filters) to ensure that they don't self-destruct. This prevents bottoming out, longer life, etc. Some subwoofers don't necessarily need subsonic filters, like small sealed subwoofers, which act like pseudo high-pass filters.16-Jan-2010
Does a subwoofer need a low pass filter?
As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker's lowest frequency response. For example, your speaker's frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer's low pass filter to 30Hz.
What should my high pass filter be set on my subwoofer?
Recommended Starting Points:
- Front Component Speakers – High-Pass Filter = 80 Hz (12 db or 24 db Slope)
- Rear Coaxial Speakers – High-Pass Filter = 80 Hz (12 db or 24 db Slope)
- Subwoofer(s) – Low-Pass Filter = 80 Hz (12 db or 24 db Slope)
Should I use HPF or LPF for subwoofer?
For example, LPF (sometimes referred to as LP) refers to Low Pass Frequencies and is used for subwoofers designed to play only the lowest notes. HPF (sometimes referred to as HP) refers to High Pass Frequencies and is used for speakers and tweeters.

What does subwoofer low pass mean?
Low Pass: This controls the crossover point. The crossover is the frequency point where the subwoofer will take over from the other speakers in your system. We always recommend starting with the crossover (Low Pass knob) set to 80Hz, but crossover points can be a personal preference.

When should I use high-pass filter?
High pass filters are most commonly used to remove low-frequency content that is not within an instrument's frequency range. As a general starting point, you should place a high pass filter on each channel and adjust it according to the lowest frequency the sound source can produce.
What does a high-pass filter do?
A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. A low-pass filter (LPF) attenuates content above a cutoff frequency, allowing lower frequencies to pass through the filter.
