mixing kick and bass help

hello i just have a couple questions regarding eqing the kick and sub bass. i always sidechain the two, so no problem there..just wondering if im eqing properly, mainly hp and low pass filters is my problem. for instance i always lp the sub bass and cut everything above 100-120 hz and hp cut everything below 40-60hz. but with the kick i still cut anything below 60hz and i cut alot of the higher out of the kick..i know its whatever sounds good, but how should i low pass the kick does it need alot of high end, where should i roll it off, it doesnt sound right if i cut of the highend like i do with the sub bass..i also boast and cut both oppositely to create space. its worth noting i make alot of dance music so im looking for a punchy tight low frequencies. also i normally use two kick samples and two snare samples which are layered. obviously both kick samples are going to be alittle different, would it be bad to boost or cut them the same or should i cut one whre i boost the other.. the kick and sub bass are so important i need to get this right.. any help on where to cut the kick would be great thanks

Also, unless you're mixing for playback on club systems or setups with seriously good subwoofers it's generally not a bad idea to high pass everything around 50Hz with a steep roll-off below that point before the final compressing/limiting is done. Nearly all playback systems apart from those can't handle anything below that frequency (or even an octave above it) in the first place, and if there is inaudible stuff going on down there it can still have a lot of energy, which can build up and trigger compressors/limiters skewing mix finalising/mastering.

One trick for adding a bit of prominence to kick drums is to slightly boost the frequency around the smack of the beater hitting the skin - what that frequency is will vary depending on the drum/sample. If you're using synthesis-generated drums doubling them with a fast, brief tom-tom or low-pitched "rimshot" that's pretty much nothing but the initial transient can do a similar thing.

Also, either as an alternative to eq or an additional thing, try using side-chain triggered compression to duck the bass during the kick's initial transient. To do this put a compressor on the bass track after any compression you may already be using. Any compressor that accepts a sidechain input will do. Then set up a pre-fader send on the kick track/bus with destination set to the compressor's side-chain. The compressor will now trigger whenever it gets a strong enough signal from the kick track. You'll need to adjust the track send level and the compressor settings until you find a good setting.

It's even possible to only trigger the sidechained compressor at specific points so it doesn't trigger on every kick strike or with a response that doesn't folow the volume or duration of the kick sample. Instead of creating a send on the kick track, create a new audio track and put a pre-fade send to the compressor sidechain on it. You can now place samples of pretty much anything on that track, set the track fader to zero and use that track just to trigger the compressor on the bass exactly when and for how long you want. To vary the compressor depth vary the volume of the samples on the trigger track, etc.

A quick-and-dirty alternative is Wave's One Knob Pumper run on the bass track, but it's not as configurable as the sidechain method.

Some great info here.
