Ofc I only meant the headphones as reference to the stereo depth added to the sound. You will want to keep it minimal on the sub freqs, in a way that is just on the verge to be appealing with headphones - but still controlled enough so you don’t loose impact on mono subs or risk vinyl incompatibility, and maybe even giving some very slight unevenness to the rumble that can be very appealing and as well glue together with the harmonics… vs. a straight clean action in the sub.
Also keep in mind that usual production seperates the steps between sound design and mixing. Maybe many people would design the maximum impact 808 bass in a rather plain way, and then give it that depth and definition in the mixing step. You need to plan this ahead.
You must view the bass as a composition of frequencies. The lowest, sub freqs where the fundamental is are rather felt than heard, and given proper mastering you cannot really tune those to have more impact than possible and usually applied. Just the sub alone will be weaker in impact than a sub with less amplitude, but lots of strong harmonics adding up to the percieved energy of the tone. The trick to make it have that energy is making sure you have harmonics/overtones/grit in sync with the sub freqs, and having reserved space for the sound in the mix. I’ve seen a trap track that did reserve almost completely the space from sub to about 400Hz or even higher just for the 808 kick - with that space reserved there was quasi nothing fighting with the 808 thus it dominated the song somewhat, in a very strong manner.
Another hint, load the tune in renoise as an autoseek audio track, cut so you only have the passages of interest to you, i.e. where the 808 kicks in and has the least amount of other noises distracting in the mix, then analyse it. Check ow the the waveform looks, the different spectrum analyser modes, check mono vs stereo, mid/side actions, lp/hp/bp filter it to isolate certain frequencies of the sound, resample the filtered and analyse on. As it is a complete mix you might miss some magic that might happen in the higher frequencies, but you should be able to find out roughly the properties of the sound, i.e. the energy characteristics of the harmonics. Then you can start trying to recreate something similar.
