The Contacta STS–S61–G is a Flush Mount Loudspeaker (Grey), included within the STS-K003L-G kit. This item can be purchased as a replacement for a damaged or defective unit but has also been succesfully used in Speech Transfer scenarios that require a discrete, robust, small loudspeaker for localised voice reinforcement or audio broadcast.

The loudspeaker unit is a compact solution that includes a 4Ω, 5W (RMS) loudspeaker delivering 85dB at 1W/1M. This particular Surface Mount Microphone is also available in Black (STS-S61-B). Dimensions are approximately 50mmD x 60mmW x 120mmH.
