low pass high pass?

so this question is probably very simple and im sure i know the answer but just to clarify, Say I low pass something(e.g. sub) to 100hz (just as an example, i dont always go that low). then high pass something (e.g. a bass drum) to 100hz. the freqs shouldnt clash right? cuz one is hi passen and the other is lo passed. even if the x over freq (on both synths) is pinned to the very left. Im pretty sure that theyd be fine but can someone just make my mind at ease? Gratzi

They still will, how much depends on the slope of the filters.

Probably easier and more accurate to eq out the frequencies as different filters work in different ways and will probably leave sounds clashing still

well im usin reason 4's stereo imagers and i always eq the sounds to make sure the freqs arent clashing but i was jw if doing what i mentioned worked for seperating the freqs

The only things I can think that could be a concern would be the slope of the filter and if there is any resonance (a little bump or spike) where the cutoff begins and tapers off.

i'd also be careful highpassing the kick that high as that is usually where the main meat is and the filters could be causing some sort of phase distorion which could be killing the fucking with your kick.
High pass the kick a bit lower and sidechain it to the sub by a few dB imo.

so if im usin reasons stereo imagers are u sayin lo pass it at a higher x over freq rather than hi passing it at a lower x over freq. then use some eq to make sure it doesnt clash with the lower freqs?

Filters and EQs are the same thing

Like Project EX said earlier it does depend on the slope of the stereo imager. Although it seems to suggest it is cutting off everything below or above 100 hz, in reality, the cut off is a gradual slope, which can be steep or gentle depending on the settings. I'm not sure what the slope is for reason's stereo imager but I'm sure you could find out somewhere. No matter what frequency you cut off on, a sidechain is definitely a good idea though as whatever happens, you will still get more headroom at the lower end of your track, and imo when it come's to EQing, the low end is the priority when it comes to mixing

Should be said, if you plan to locut eq, don't use really steep cutoffs, lest phasing issues start to fuck your life.

A picture example would be great for what you're talking about exactly
Are you saying to leave a "hill" slope rather then a cliff? when you cut off? And why/how would it phase?

don't do that. imo.
just use a shallower gradient. when ur locutting or highcutting. It's not a terrible thing for your mix if sounds overlap. check out this eq tutorial

I couldn't tell you the physics of how phase problems arise, just that you don't want them.

damn i always use eq to low pass/high pass and i usually use a 48db slope, i guess ill have to try and mellow them out

^^ Ya someone on here said before that generally you shouldn't make a boost(or cut I'm pretty sure) over 6dB. I've been following that guideline closely and I think it helps keep me from going overboard.
That said, do filters mess with the phase like eq does?

I'd think so, as they work in very similar ways, but I'm not sure.

An EQ is a collection of filters, theyre just not high and lowpasses. They both cause some kind of phasingdifference unless specifaclly created NOT to do that.

Linear phase EQ doesn't have these phase problems am I correct? Latency is a huge issue, though.
