What should my low-pass filter be set on my subwoofer?

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.

Is Butterworth filter a bandpass filter?

It was invented in 1930 by the British engineer and physicist Stephen Butterworth in his paper titled “On the Theory of Filter Amplifiers”. The frequency response of the Butterworth filter is flat in the passband (i.e. a bandpass filter) and roll-offs towards zero in the stopband.

Is bandpass a low-pass filter?

A band pass filter is a combination of a high pass and a LPF. It allows only a select range of frequencies to pass through. It is designed such a way that the cut off frequency of the LPF is higher than the cut off frequency of the high pass filter, hence allowing only a select range of the frequencies to pass through.

What does low pass do on a subwoofer?

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.

Why bandpass filter is used?

In a receiver, a bandpass filter allows signals within a selected range of frequencies to be heard or decoded, while preventing signals at unwanted frequencies from getting through. A bandpass filter also optimizes thesignal-to-noise ratio (sensitivity) of a receiver.

What happens to the frequencies above or below the band of a bandpass filter?

Frequency Response of Band Pass Filter The range can be quite large depending on inherent characteristics of the circuit. The signal is attenuated at low frequencies with the output increasing at a slope of +20 dB per decade or 6 dB per octave until the frequency reaches to lower cut off frequency ‘fL’.

What phase should a subwoofer be set to?

Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to 180-degrees.

When would you use a low-pass filter?

A low-pass filter can be used very effectively to mimic the sensation that one signal is further away from the listener than another (unfiltered) signal. This technique can be used very quickly, and easily to establish spatial contrast between two signals, especially if they’re separated in the stereo field.
