SSOUNDS LS310 Sub
Subwoofer duplo de 18″ voável para arrays LS310, alcance de 23 Hz, pico de 143 dB, voa no mesmo hang.
O LS310 Sub completa o sistema LS310: um subwoofer duplo de 18″ com design de bass-reflex e corneta, construído para voar dentro do array LS310 em um sistema de içamento de liga de alumínio, estendendo a largura de banda do hang até 23 Hz sem um hang de sub separado. Ele recebe uma única alimentação NL4 do amplificador do sistema, então o percurso do sub permanece independente do loom NL8 dos tops. A SSOUNDS especifica drivers para pico de 143 dB, em um gabinete de madeira compensada de bétula reforçada com tratamento resistente à água e poeira. Empilhe no chão quando o projeto exigir graves de piso.
Part of the LS System
Flyable dual-18 subwoofer on the shared array hardware.
LS stands for Line Source. A line source, in the acoustic sense: coupled elements radiating as one continuous source, so vertical pattern is set by the length of the array rather than by the individual cabinet.
Key features
- Flies inside LS310 arrays on the same titanium rigging, no separate sub hang
- Its NL8 carries the whole array loom: sub, LF, MF and HF on one cable per box
- 23 Hz reach and 143 dB peak SPL
- 2 × 18″ cone drivers, 4″ coil
- Horn-designed bass-reflex cabinet in braced birch ply
- Water- and dust-resistant treatment for outdoor work
- CardioSteer presets steer low-frequency energy off the stage

Physical
Measurement conditions
- Maximum SPL is the peak level at 1 m, driven with pink noise at crest factor 4 to the clipping point of the recommended amplifier, with the SSOUNDS system preset applied. Full-range enclosures are specified under free-field conditions; figures marked half-space are specified over a reflecting plane, the condition subwoofers are deployed in, which adds approximately 6 dB.
- Frequency response is specified on axis at 1 m in a free field. The tolerance the figure is referenced to is stated alongside it; where no tolerance is given, the figure is the −6 dB bandwidth.
- Sensitivity is specified at 1 W into the nominal impedance at 1 m on axis, averaged across the pass band of the enclosure.
- Recommended amplifier power is the amplifier output SSOUNDS specifies for this enclosure, driven with the SSOUNDS system preset. It guides amplifier selection and is not an AES power-handling rating for the transducers.
- Nominal impedance is the manufacturer's rating for amplifier load calculation; minimum impedance across the operating band may be lower.
- Net weight excludes packaging, flight case, accessories and optional rigging hardware.
- Dimensions are stated in millimetres and exclude protruding rigging hardware, handles and connector panels unless noted.
- All figures are typical values for production units specified under the conditions above. Individual units may vary within published tolerances.
Directivity
Directivity computed by the SSOUNDS system prediction engine from this product's driver complement, the same dataset the printed data sheet uses. 1/24-octave band-power resolution; values are dB relative to on-axis.
System operation
Recommended: SSOUNDS D24X, one channel per LS310 Sub (4 Ω) with the LS310 Sub preset loaded.
