Sub-Bass

Frequencies roughly below 60 Hz that are felt more than heard on a big system, forming the low-end weight beneath a bassline.

Sub-bass refers to the lowest audible frequency range, roughly 20 to 60 Hz, produced by the lowest register of a kick drum or bassline. On a club system this range is felt as physical pressure rather than a distinct pitch, and it accounts for most of a track's perceived weight and body.

Why it matters

Sub frequencies accumulate fast. Running two tracks with active sub-bass simultaneously will overload the low end and risk clipping the system amplifiers, so one track's low EQ must be cut before the other's comes in.

Frequently asked questions

Sub-bass refers to frequencies roughly below 60 Hz, below what most speakers can clearly reproduce. A bassline is a melodic pattern that can span multiple frequency ranges. Sub-bass is the lowest, often inaudible-on-small-speakers layer that adds physical weight and chest pressure on large club systems.

Consumer headphones and small monitors roll off heavily below 60-80 Hz. Sub-bass frequencies are designed to be reproduced by large subwoofers and felt physically in your body rather than heard clearly. This is why mixes prepared on small speakers sometimes sound thin or overwhelming on a club system.

Use a high-pass filter to remove the sub frequencies from the outgoing track before or during the transition. Sub-bass from two tracks doubles up fast and creates a boomy, undefined low end that can distort the system. One sub at a time is the standard approach.

I DJ and produce as so I so — downtempo, minimal, dub house, tech house, and techno (releases on Spotify and SoundCloud, links above). Everything I write here comes from my own gigs, studio sessions, and library cleanups: the rules I follow, the failure modes I've actually hit, and the workflow I use when nobody's watching. If a technique didn't earn its place in my own sets, it doesn't make it into a tutorial.
