SSOUNDS LC9.4W
IP66 die-cast aluminium 9 × 4.5″ column, 128 dB peak, for long platforms, courtyards and the call to prayer.
Long outdoor spaces need level at distance and a pattern that does not hit every building on the way. The LC9.4W is nine 4.5″ full-range drivers in an IP66 die-cast aluminium column 1100 mm long, rated 125 dB continuous and 128 dB peak with 99 dB sensitivity. The vertical pattern is 10° and the horizontal 160°. We specify it for long railway platforms, mosque courtyards, minarets and the call to prayer, and open public areas that need speech carried a long way in all weather.
Part of the LC System
Nine 4.5″ drivers, 128 dB peak: long platforms, courtyards and the call to prayer.
LC stands for Line Column. Drivers stacked in a vertical line that radiates as one line source, so the vertical pattern is set by the length of the column: energy lands on the listeners and stays off the reverberant ceilings and walls around them. The outdoor W models carry the same principle in IP66 die-cast aluminium, and the D models carry their own amplifier and take Dante audio and PoE power on one network cable.

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.
- Coverage angles are nominal −6 dB values averaged across the pass band. Per-octave directivity data is available from SSOUNDS system design support for prediction and modelling.
- 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.
