SSOUNDS LC8.4H
Two-way 8 × 4.5″ plus 8 × 1″ column, 640 W AES, 128° × 27°, for conference halls, auditoria and worship.
Conference halls and auditoria ask a column for more than speech: walk-in music, video playback and a full room at the end of the day. The LC8.4H is a two-way line of eight 4.5″ cone drivers and eight 1″ high-frequency drivers in a 969 mm cabinet, rated 640 W AES and 129 dB peak. The vertical pattern holds to 27° and the horizontal to 128°. We specify it for conference and lecture halls, auditoria, houses of worship and large commercial spaces that need more headroom than a full-range column gives.
Part of the LC System
Two-way, eight 4.5″ drivers with eight 1″ high-frequency drivers, 129 dB peak: conference halls, auditoria and worship.
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.
