SSOUNDS P4
Coaxial 4.5″ install loudspeaker in a white aluminium cabinet on a U-bracket, 90° × 90°.
The P4 is the smallest install cabinet in the P series: a 4.5″ coaxial driver with a 1″ high-frequency driver on one axis, in a white aluminium cabinet on a U-bracket, covering 90° by 90° from 90 Hz to 20 kHz with 116 dB maximum SPL. It handles 60 W AES at 8 Ω and connects on an NL4 speakON. We specify it for shop fronts, display areas, bars, under-balcony fill and foyers where the loudspeaker sits in view and has to look like part of the interior.
P stands for Point Source. One cabinet as the whole source rather than a coupled array: coverage is set by the cabinet's own horn, waveguide or driver layout, and is the same whether one is deployed or several. A T marks a model that also runs on a 70/100 V line.

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.
- 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.
