What Is a Sound System?
What is a sound system? In reggae, dub and UK bass music, not just a PA: a named outfit with its own speakers, amplifiers, control tower, records and crew. The idea grew out of Kingston, Jamaica, in the 1940s and came to the UK with Caribbean migration.
Two meanings
In general audio, a sound system is any rig that makes sound louder: mixer, amps, speakers. In sound system culture a "sound" is an identity. It has a name, a following, its own selection and usually speakers its crew built or commissioned. Dancers follow a sound for its tone and its selectors as much as its volume. This section of the site is about the second meaning.
Origins
Sound systems became popular in Kingston in the 1940s. Operators loaded a truck with a generator, turntables and large speakers and set up street dances, playing American rhythm and blues. By the mid-1950s sound systems were more popular at parties than live musicians.
The leading operators of that era included Clement "Coxsone" Dodd, Duke Reid and King Edwards, with Tom the Great Sebastian among the earlier sounds. Operators began recording local musicians; what began as an attempt to replicate American R&B evolved into ska. The culture reached the UK with mass Caribbean migration.

The parts of a sound
- Speakers. Separate boxes per band, commonly sub, bass (kick), mid and top in a four-way system.
- Amplifiers. At least one channel per band, so each set of drivers has its own power and limiting.
- Control tower. Preamp, crossover, EQ and effects, played live by the operator. Many are custom built.
- Records and crew. Selector, operator, MC and the people who carry, stack and wire it. See selector, operator and MC.
Built around the bass
Reggae, dub, jungle, drum and bass and dubstep are written around the bassline, and a sound is judged on how clean and weighty its bottom end stays at level. That puts the money and the engineering into the sub cabs: scoops, folded horns and large reflex boxes loaded with 18" drivers. Each trades size, efficiency and extension differently. See scoop vs reflex vs horn.
For the sub stack, the numbers that decide it are continuous power, coil size and displacement. Our WM18X451 is built for scoops and folded horns (1800 W RMS, 4.5" copper coil, double spider, £345); the WM1850/8 is rated 1800 W AES with a 125 mm coil and 1493 cm³ of displacement, at £275.
Sound system vs club PA
| Sound system | Installed club PA | |
|---|---|---|
| Owned by | The crew; travels with them | The venue |
| Cabinets | Often hand built to the crew's chosen design | Usually commercial boxes |
| Control | Operator plays the preamp live | Often locked processor settings |
| Identity | A named sound with a following | Part of the room |
| Music | The sound's own selectors | Whoever is booked |
Today
Sounds play carnivals, dub nights, warehouse dances, festivals and community events across the UK. Rigs range from vintage valve amps and hand-built preamps to traditional cabs driven by DSP and Class D. Many crews start with a pair of subs and a pair of tops and grow box by box. Starting out: planning your first sound system.
Safety
Lift large cabs with at least two people, stack only on firm, level ground and never climb a stack. Protect your hearing and the crowd's. Mains distribution should be handled by a competent, qualified person.

Questions
What is a sound system in reggae?
A named crew with its own speakers, amplifiers, control tower and records, known for its selection and its sound. It plays dances, carnivals and clashes, and is operated live by its members.
Where did sound systems originate?
In Kingston, Jamaica, where they became popular in the 1940s playing American rhythm and blues at street dances. The culture came to the UK with mass Caribbean migration.
What is the difference between a sound system and a PA?
A PA is any amplification rig, often owned by a venue. A sound system in the cultural sense is a crew's own rig and identity, usually custom built and played live from its own control tower.
Why are sound systems so bass heavy?
The music they play, from reggae and dub to jungle and dubstep, is built around the bassline. Sounds put most of their engineering into sub cabinets, typically scoops, folded horns or large reflex boxes with 18 inch drivers.
