Acid techno is a harder, more driving offshoot of acid house that blends the squelching lines of the Roland TB-303 with the pounding rhythms and industrial edge of 1990s techno. It favors relentless 4/4 kicks, hypnotic 16th‑note bass patterns with accent and slide, and aggressive resonance sweeps that create a distinctive, corrosive timbre. Emerging largely from the UK free-party and squat-rave scenes, acid techno emphasizes raw energy, immediacy, and live hardware performance. Compared with acid house, it is faster, tougher, and more percussive; compared with mainstream techno, it leans heavily on the 303 as the central hook and motif. Typical tempos range from about 135 to 150 BPM, with arrangements built for long, tension-and-release transitions, filter rides, and layered drum machine grooves tailored to large, physically immersive sound systems.

Dub techno is a minimalist offshoot of techno that fuses Detroit/Berlin techno rhythms with classic Jamaican dub studio techniques. It emphasizes space, depth, and decay through extensive use of tape‑style delays, spring/plate reverbs, and filtering. Typical tracks hover around 118–130 BPM with understated 4/4 drums, deep sub‑bass, and repeating, softly struck chord stabs (often minor 7ths or suspended voicings) that are washed in reverb. The result is a hypnotic, immersive sound world—grainy, foggy, and textural—where small timbral changes and delay tails provide the narrative. The genre coalesced in early‑1990s Berlin around Basic Channel and related labels, drawing on Detroit techno’s futurism and Jamaican dub’s mixing philosophy while embodying the austere spatial aesthetics of the Berlin scene.

Minimal dub is an electronic music style that fuses the spacious, echo‑laden mixing techniques of Jamaican dub with the stripped‑down structures of minimal techno. Hallmarks include deep sub‑bass, sparse drum programming, long feedback‑rich delays, spring/plate reverbs, and filtered chord stabs that drift through large amounts of negative space. Tempos typically sit near 118–128 BPM, but the sensation is unhurried and hypnotic due to restrained arrangement and micro‑variation rather than overt melodic movement. Where classic dub foregrounded live rhythm sections and remix performance, minimal dub translates those practices to drum machines, samplers, and DAWs, treating the mixing desk itself as an instrument while maintaining a minimalist, iterative groove.
