The SW-004 is a compact baffle-mount loudspeaker designed for 100 V public address systems. Built on a 13 mm thick black-coated chipboard panel, it houses a 119 mm twin-cone driver and an integrated 100 V transformer, making it suitable for installation in suspended ceilings, enclosures, or technical ceilings.

The bottom of the panel is equipped with four rubber feet that allow vibration-free placement on perforated ceiling plates or other surfaces. With a nominal power of 4 W, excellent speech clarity, and a wide 180° dispersion at 1 kHz, the SW-004 is ideal for background music and announcements in schools, offices, and utility buildings.
