I've certainly worked on production for some projects where there was musical content down to around 25 Hz that went to Printing that way. Why would I do that? Subsonic filters for avoiding reflex speaker unloading are literally subsonic, not within the clearly audible frequency range. I've never cut off everything below 40Hz in CD mastering.

Active tone circuits certainly are fun, I've designed a few in my younger years. Those shunning low frequencies aren't necessarily correct in assuming the frequency itself is the problem as much as the entire circuit design being not to their liking.Īnyhow. My point is correct still that a 100 Hz or even 20 Hz center frequency for a bass control can sound amazing on a bass guitar if the q and order of the filter are setup well. Shouldn't kill the speakers though as long as peaks are tamed. That is the basis for Alembic's series 1 filter where q made a much bigger difference than center frequency.Īnything below 30 hz. Honestly without changing the frequency you can dramatically change overall tone very much sounding like you're changing the frequency just by changing q and output level. If you get thump from 125Hz that's great but it isn't where I get it, however again it depends on the eq slope and q. Fundamental is also very audible though and does provide the very definition of 'thump' in bass guitar tone which makes my previous post relevant to the topic. I'm aware of harmonics being more important to tone identification and uniqueness. On your instrument anything between 60hz and 100hz for a bass knob is just about perfect, frequency depending on the flat EQ voice of the instrument. Warwick basses are really strong and lovely in this range, which makes them high end imho. Between 1k and 4k there's a lot of painful noise going on with a lot of basses, this is the hardest freq range to get right for bass and guitar. More growl is obtained by boosting somewhere between 500hz and 800hz depending on the voice of your instrument. When wanting more thump in the bass while mixing one usually dials in some more 125hz.

The 'Bass' dial on most hifi stereo amplifiers is at 100hz.

This is why the 30hz control on a Trace Elliot's 12 band EQ is coloured red. Your amp will also sound tighter as it won't throw most of its power into a useless part of the audio spectrum. Really, anything under 30hz you want to cut off to keep your speakers from flapping out. What is most audible to the human ear are the harmonics of those ultra low tones. Yet you get to hear nice and full sounding low B's.Īlso, a lot of hi fi stereo speakers don't go under 50hz. In most CD productions anything under 40hz gets cut off mastering. Mixing is not about the fundamentals but rather about harmonics.
