Description

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 4 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 4 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.
