A high-pass filter (hpf) is an audio frequency filter that cuts (filters out) frequencies below a set level. For example, if you set a high-pass filter at 300hz, you’d lose a lot of the bass sound from instruments that have frequencies in that lower range.
Thus, the recommended settings are a HPF (5000 Hz) for the front tweeters, a HPF (80 Hz) for front midrange, a HPF (80 Hz) for rear speakers and 12 dB or 24dB slope. If rear speakers (passive) are added to this system, the settings will change a little bit.
Secondly, what is HPF slope? A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. The slope of filter attenuation is usually quantified in decibels per octave.
Also know, what should I set my HPF and LPF to?
You usually set the HPF with a steep slope say 24db/octave because you are trying to protect the sub from damage and a 12-18db/octave on the LPF because you want it to kinda “blend” in with your mids. The steeper the slope (db/octave) the less your sub will creep into the neighboring frequencies.
What Hz is best for bass?
||20 to 60 Hz
||60 to 250 Hz
||250 to 500 Hz
||500 Hz to 2 kHz

What is a good crossover frequency?
The most common crossover frequency recommended (and the THX standard) is 80 Hz. On-wall or Tiny ‘satellite’ speakers: 150-200 Hz. Small center, surround, bookshelf: 100-120 Hz. Mid-size center, surround, bookshelf: 80-100 Hz.
What does LPF and HPF mean on an amp?
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. This is because front channels are typically always used for speakers.
How do you set a crossover frequency?
Setting the Crossover Set the crossover point 10 Hz higher than the low end of your speaker’s tolerance range. If you don’t know the frequency range of your speaker, use a subwoofer matching tool. Listen for smooth transitioning between the subwoofer and the speakers.
What should LPF be set on AMP?
Set the LPF at 60-80 Hz. Most amplifiers have a 12 dB crossover slope on the LPF, so if you set the LPF higher, you will get punchy bass and it will hit very hard, but if you keep it at 60-80 Hz you will get smoother lower more pleasant bass.
How do you set a low pass filter?
Setting the low-pass filter for the subwoofer output (Subwoofer Low Pass Filter) Select [Setup] – [Audio Settings] from the home menu. Select [Subwoofer Low Pass Filter]. Select the setting you want. On: Always activates the low-pass filter with a cutoff frequency of 120 Hz. Off: Does not activate the low-pass filter.
When should I use high pass filter?
A high-pass filter is used in an audio system to allow high frequencies to get through while filtering or cutting low frequencies. A high-pass filter is used with small speakers to remove bass, for example.
How do you set a subsonic and LPF filter?
Turn your Subsonic Filter down to 10Hz then slowly turn up the filter frequency until you hear it take effect on your sub bass. The Subsonic is now correctly set. 5. Turn the Low Pass Filter to the setting that allows for the most accurate sub bass sound for your system.
What frequency should a subwoofer be set at?
How do I adjust the low pass filter on my amp?
Make sure those are all turned off, too. Start by turning the gain down, and turn off your filters and bass boost. Turn the gain up until it distorts, then back it off until the sound is clean again. Adjust the low-pass filter downward to eliminate high- and mid-frequency notes. Now play with the bass boost.
How do you test a crossover?
Testing the crossover with a multimeter is also possible. Use a signal generator (e.g. a PC s/w) to drive the crossover with discrete sine waves of varying frequencies. The low frequency output of the crossover should show a drop in voltage as frequency increases. The HF output should show the opposite.
