DnB sub-bass is a synthesised or sampled deep pattern felt physically through powerful sound systems, not just heard

DnB places great importance on its bassline as a deep sub-bass pattern in the low-frequency range — typically felt physically through high-powered sound systems. Bass lines originate primarily from synthesisers or sampled sources rather than bass instruments. There has been considerable exploration of different timbres in the bass line region, particularly in techstep and neurofunk, where bass sounds became metallic, growling, or industrial. The sparse arrangement of DnB tracks deliberately clears mid-range space to allow the bassline to occupy a wider sonic bandwidth. DnB parties are often advertised as featuring extraordinarily loud and bass-heavy sound systems precisely because full appreciation of the sub-bass requires physical playback capability.

Examples

A smooth DnB sub-bass patch: sine oscillator at 40–80Hz, minimal harmonics, long sustain. A neurofunk growl: heavily distorted, modulated bass with aggressive filter sweeps. Same low register, radically different timbre, both legitimately DnB.

Assessment

Design two contrasting DnB bassline patches — one smooth sub-bass (liquid DnB style) and one distorted growl (neurofunk style). Describe the synthesis parameters that differentiate them and explain how each serves its subgenre.
