yeah i wouldnt cut at 40hz, sure you might not hear that sub but you will certainly feel it, im sure most good club systems will play down to that range
i have an eq8 set to 30hz (with a q of about 0.6) on my master, seems to do the job |
Q is absolutely different for every EQ. Just because 1.41 is one octave (I really hope I got that right from memory), it doesn't mean it's the same for every other EQ. Also why apply it on the master when it isn't needed to begin with. EQ is something you only want to apply when you have to, not because it's conventional. |

Anyone who cuts everything below 40 Hz is a noob. Sorry, but it had to be said. We can hear (and certainly feel) right down to 20 Hz. Placing a high-pass filter at 40 Hz will mean 40 Hz will be reduced by 3 dB! Sub-sonics are a good thing if they're kept at the right level so they don't dominate the bass, but provide enough support to the mix. |
It barely makes a difference either way, lets not kid ourselves here. And your 3db reduction in db actually speaks against your point, not for it. Thats WHY so many people cut it is because of how much more headspace lower frequencies remove from your mix in general. Its smarter to compensate with higher frequencies. Which is why YOU sound like a noob. |

can anyone verify this?
12dB/oct = 1dB/semitone?
i totally agree with megaman, damping from your baseline note and down, somewhere between 30-40Hz. hence my question above. |

I'm sorry. Atlantis' street cred's outweigh yours. Try and make your low freq's managable instead and rock the dancefloor. |

@ the OP; sub bass is from at least 80 downwards, not from 20-40 hz. That range is usually filtered out in most tracks, since subs don't usually handle them and they eat headroom. So you don't really need to monitor that range.
Personally, I think its best to cut from 35 or 40 downwards and boost around 80-90. that way you get more thump and chest rattle and use less headroom and create less floor rattling. |

spose i could just put it on the kick channel, thats the only other channel i dont high-pass
i dont put it there because its conventional, but because i need to, my mixes would be a bit on the boomy side if i didnt - anyways, each to their own! |

Yeah, I shelved 30 Hz by -4 dB in a recent project and left it for the bass to fill the sub. If it sounds better, then surely do it! |

Why do you need to know, if I may ask? At 12 dB/oct, if you place a high-pass filter at 262 Hz you'll get a 3 dB reduction there, and a 12.04 dB reduction at 131 Hz, with a 24.08 dB reduction at 65 Hz, if I believe (with 523 Hz being a lesser number), but I'm no expert when it comes to this. I'm pretty sure it won't be linear though, due to the nature of dBs being logarithmic...
My point continues to be though, sub-sonics have their place in the mix and shouldn't just be cut off. If you analysed thousands of tracks you'd see they all follow a pattern, and that is a gentle roll-off in the sub-sonics, but they still have their place. If I gave you a track that had already been high-passed in the kick and bass channels (and you didn't know), would you cut it again on the master, hence increasing the Q? Why? Roll it off only if it needs to be rolled off! |

| well both dB and frequency (scales/octaves) are logaritmic so thats one of the reason i asked, i think it actually is linear as both the measurements are logaritmic (not linear on its own but compared to each other). So it does seem its damped 1dB pr semitone imo. The reason i asked was because i was wondering if it damped suddenly all the 12dB through the whole octave or whether it went smoothly but after thinking i know its smooth. |

| I've just thought about it more and it can't be linear, simply because the curve on a paragraphic EQ isn't a straight line... |

+1. It's not like were making true Dub or Raggae here. below 40 just makes rattle in large PA or club systems, it barely has any actual sound as such, more just deep vibration.
The other thing that people are forgetting to ask in this thread is how well do your mid level 6" drivers in your monitors handle 40hz? Answer: either not well or not at all.
So good luck mixing accurately with that.
Yes, if you're working on serious monitors then maybe you can try managing 40hz as a specific effect but otherwise don't kid yourself or give advice on this forum about doing it. It's just not a realistic concern.
And the sub argument doesn't work either because once again, we don't mix in 2.1 do we? There's no LFE channel..... |
