Jul 10, 2023 · A highpass filter (HPF) works to block unwanted frequencies in the audio signal output (low frequency sounds) below the crossover point from reaching a speaker. Everything …

Mar 6, 2025 · I'm wondering if I could use that global EQ as LPF and HPF. It has Low, Mid, and High, and the frequency range is the same for all three: 20Hz to 20kHz, with -12 dB to +12 dB. …

Dec 21, 2022 · The mini Vong may only be 12dB/octave but the HPF/LPF Vong has a 12dB/octave 30Hz filter followed by a 12dB/octave variable filter, bringing you closer to the …

Jun 3, 2021 · Usually with crossovers they have a slope being -x db per octave. Usually it's a hpf (high pass filter ie high sounds come through) of -12db/octave with a lpf (low pass filter) of …

Nov 3, 2013 · Let's start simple with crossover filters, high pass (HPF), low pass (LPF) and bandpass. Basically they are filters that divide up the frequencies and allow/pass the proper …

Jul 20, 2012 · I will be checking this out for myself via trial and error, but just wondering what people use for their HPF setting -- I've seen people use everything from 6db/oct to 36db/oct …

Oct 25, 2020 · The improvement in sound provided by an HPF tends to be fairly subtle. An HPF may give you a bit more usuable headroom. However, most amps already have some high …

May 30, 2011 · Any HPF is going to have a gradual rolloff. It's not a hard cutoff as some people think. So setting an HPF to say 70Hz will roll off everything below 70Hz by anywhere from 6db …

The Thumpinator cuts 36db/Oct from 25hz so it effectively stops a lot of the Octave signal getting through if it drops below a low B Flat. So it protects the speakers and stops the octave turning …

An audio high pass filter (HPF) is an equalization tool that attenuates all frequencies below a set point. In other words, high pass filters remove low frequencies while allowing high frequencies …
