Both for ninja accuracy, below 20hz just pushes air on a lot of systems and generally doesn't add any weight.RandoRando wrote:Is it just me or does anyone else not notice that 75% of the people in here and confusing high pass and low pass?
HIgh Pass, your letting the HIGH frequenices PASS through. High passing a sub@20hz would allow the sub to play everything ABOVE 20 Hz
Low pass a sub @60Hz would allow the sub to play everything BELOW 60Hz, which would allow the mix to leave room for the kick which could be 60-120 Hz.
High pass /''''''''''
Low pass ''''''''''''''\
Do you have any evidence on this?dubesteppe wrote:40 seems preatty high, most car subs can hit around 30. big systems respond even lower. most people high pass at 20
I dont think boosting sub frequencies are a good idea personally.sycotronix wrote:i low pass sub @ 65 - 70 hz with boosting around the 55hz range depending on the fundamental freq ,high pass kik @ 70 hz.so even if my sub & kik is playing together , they dont interfere with each other & makes mix muddy.
i hope im doin it rite..any comments pls
This sounds right to me but what do I know...joshisrad wrote:I don't do SHIT to my sub. No need to lowpass or highpass it. Unless you are going for a musical effect where the sub bass is reduced in volume when you play higher notes, in which a lowpass would be acceptable. There is no muddiness or any other frequency at ALL if you are using a sine wave.
thats where all the low weight is!! my subs are tuned to 30hz. cut 20 hz and below, its not really neccessary but if you use linear phase EQing you might gain a few DB headroom.Refuzed wrote:i normally cut everything below 30hz

A sine wave only occupies a single frequency, not a range. Its the purest waveform there is.cmgoodman1226 wrote:A sine wave has no harmonics or overtones, but it still occupies a range of frequencies.
I might be wrong, but i think this is only true to a point. Firstly, its good to learn the conventions so you know why they're there, then you can decide if you wish to break them. Secondly, i don't think some things should be changed, like keeping the sub in mono or filtering out <20hz frequencies which don't do a tune any good.Ghost of Muttley wrote:Using the same formula every time is how you end up with a formulaic sound, the more varied the conventions the better.
But its nice to improve said formula still.Ghost of Muttley wrote:Using the same formula every time is how you end up with a formulaic sound, the more varied the conventions the better.
Its true that you need to learn technique before you can develop a style, but that's not the same as sticking to a set approach every time imo.VirtualMark wrote:A sine wave only occupies a single frequency, not a range.

I think you're misinterpreting information. I understand the theory behind a sine, but load a pure sine into any spectrum analyzer and tell it's only occupying 1hz.VirtualMark wrote:A sine wave only occupies a single frequency, not a range.
