SSOUNDS M4.2P
Compact two-way cabinet, 2 × 4″ in V formation with a compression driver, 100 dB sensitivity, 126 dB peak.
The M4.2P is a compact two-way cabinet for fill and foreground duty where a small box has to keep up with a larger system. Two 4″ long-excursion drivers in V formation sit beside a compression driver with a 0.5″ throat and 1″ voice coil, giving 100 dB sensitivity and 126 dB peak at 1 m from 95 Hz to 20 kHz. The name follows the M3 columns: driver size, then driver count. We specify it for front fill, under-balcony and delay positions, bars and foyers.
M stands for Modular. One install and portable platform from the smallest fill cabinet to the fifteen-inch point source, with the subwoofers and columns that go with them, on a single amplifier and bracket language.

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.
- All figures are typical values for production units specified under the conditions above. Individual units may vary within published tolerances.
