The FRWS 5 uses a lightweight cone and soft surround to reproduce speech and music in a small square frame. Its wide dispersion suits narrow speaker columns, while the compact size also works in models and electronic monitoring equipment. This 8 Ω version handles 4 W rated power; the balanced response region starts around 250 Hz.
Typical applications
- Narrow speaker columns
- Electronic monitoring
- Model construction

Installation and cabinet guidance
Allow for a 45 mm opening, 50 mm square frame and 44 mm fixing pitch. Tighten the four fixings evenly without distorting the basket, and leave access to the solder lugs.
Mount on a rigid panel with a continuous seal around the frame to prevent air leaks and rattles. Keep the cone and surround clear of the grille and internal parts.
Use an amplifier suitable for the 8 Ω load and follow the polarity marks. Solder without prolonged heating, insulate the joints and secure the wires so they cannot touch the cone or pull on the lugs.
For a 100 V line system, connect through a correctly rated line transformer; do not connect this low-impedance driver directly to the line.
Use this impedance version’s enclosure parameters when developing a cabinet, and test the response at the intended listening level. Allow for the volume occupied by the driver and keep damping material clear of the cone and terminals.
