Why your 808 disappears on small speakers
An 808's fundamental, the note itself, usually sits somewhere between about 30 and 60 Hz. Phone speakers, laptop speakers and most earbuds give you very little below roughly 150 to 200 Hz. So on those speakers, the part of the 808 that carries the note is mostly gone.
The reason you can still hear a bass line on a phone is the harmonics: the overtones an octave and more above the fundamental. Your ear hears that stack of harmonics and fills in the missing note on its own. If your 808 is close to a pure sine wave, it has almost no harmonics, so there's nothing left for the ear to work with.
1. Give the 808 harmonics
Saturation or distortion adds overtones in the 100 to 500 Hz range, which small speakers can play. Go for density, not fuzz: if the 808 starts to sound harsh or buzzy on big speakers, back off. A little saturation on the 808 itself is usually better than a lot on the whole mix.
2. Make the hit land
The first 20 to 40 milliseconds of an 808 are what you feel as the knock. Bringing up that front edge, without bringing up the click on top, makes the 808 read as punchy even when the speaker can't move much air.
3. Control the tail
Long 808 tails overlap the next note in fast patterns and turn into a low rumble that eats headroom. Shorten them where the pattern is busy, and let them ring where there's space. A tight tail also leaves room for the kick.
4. Keep any sub layer in phase
If you layer a sine sub under your 808, or use a sub enhancer, check it in mono. A sub that's out of phase with the 808 cancels it, and you lose low end exactly where you were adding it. Notes that change pitch (glides, slides) are where layered subs drift out of phase most.
5. Check your lowest notes
The lowest notes in an 808 line (an A0 sits at 27.5 Hz) are the first to vanish on small speakers and the easiest to lose under a limiter. Play your track on a phone, on earbuds and in a car. If the low notes drop out while the higher ones come through, those low notes need more help than the rest.
How SUBFORCE handles it
SUBFORCE is our low-end processor for kicks, 808s and bass. It works on the low end only, so the click and the top of your sound pass through untouched:
- SUB follows the pitch of every note and glide. Higher notes get a synthesized octave underneath; low notes (like that A0) get their own fundamental lifted instead, so nothing is wasted below what speakers can play.
- PUNCH brings up the hit you feel, not the click.
- BODY adds sustain and harmonic density from an always-on analog-style circuit, which is what makes the 808 read on small speakers.
- TIGHT shortens the tail without choking sustained notes.
- Phase Intelligence makes sure nothing SUBFORCE adds ever cancels the low end you already have.
It comes with presets made for this: 808 Phone Speaker for translation, 808 Hard Hitter for fast drill and trap patterns, and 808 Long Glide for sustained 808s with slides.
