Description

The WS 25 E has a coated paper cone, a rubber surround and an extended rear pole plate for long excursions, and its basket shape makes it a practical replacement for the woofer in many standard hi-fi speakers. This 8 Ω version takes 80 W rated power, resonates at 34 Hz and fits a 225 mm cut-out.

Typical applications

  • Replacement hi-fi woofer
  • Large multi-way speaker systems

Installation and cabinet guidance

Allow a 225 mm panel opening. The frame is not round: it measures 245 mm across the flats and 283 mm across the corners, with 6 mm fixing holes set out at the corners on a 262 mm circle, so mark them from the driver itself. Behind the panel the driver needs about 106 mm of clear depth for the basket and the 80 mm magnet, with room beyond that for the terminals and the wiring.

Mount it on a rigid baffle with a continuous gasket or sealing strip between the frame and the panel. The pressed flange is thin, so tighten the fixings evenly and only enough to seal, and keep the cone and the rubber surround clear of the grille and of any internal bracing. The terminals take 5.2 x 0.8 mm blades on the positive side and 2.8 x 0.8 mm on the negative, so check blade width before choosing connectors, observe polarity and use an amplifier or crossover suited to the 8 Ω load.

The lower cut-off depends on the enclosure volume and tuning, so test the driver in the intended enclosure at the intended listening level before finalising the cabinet.

If it is going in as a replacement, check the cut-out, the fixing pattern, the depth behind the panel and the impedance against the original driver before ordering.
