SSOUNDS LC16.3
16 × 3″ full-range column, 127° × 24°, for announcements and speech in airports, stations and mosques.
Large public interiors are built from hard materials, and in them intelligibility is lost to reflections long before it is lost to level. The LC16.3 is sixteen 3″ full-range drivers in a 1401 mm straight line inside a slim cylindrical wooden enclosure. The length of the line keeps the vertical pattern to 24°, so energy is directed at the floor where people stand and kept off high ceilings, while the 127° horizontal covers a wide hall from a single wall position. It is the LC column for airport terminals, railway station concourses, metro halls, mosque prayer halls and large houses of worship, where announcements and the spoken word have to be understood at the back of a reverberant room.
Part of the LC System
Sixteen 3″ drivers in a 1,401 mm cylindrical column, 127° horizontal: announcements and speech in airports, stations and mosques.
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.
- Power handling is rated to AES2 using pink noise with a 6 dB crest factor over a two-hour period. Programme power is twice the AES rating; peak power is four times.
- 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.
