Description

The WS 17 E has a coated paper cone, an elastic rubber surround and an inverse dust cap, and its balanced response suits it to woofer duty or to the low-midrange band of a four-way system. This 8 Ω version takes 60 W rated power, resonates at 45 Hz and shows 5.8 Ω d.c. resistance with a total Q of 0.81.

Typical applications

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

Installation and cabinet guidance

Allow a 150 mm panel opening. The frame is not round: it measures 165 mm across the flats and 188 mm across the corners, with 5 mm fixing holes set out at the corners on a 175 mm circle, so mark them from the driver itself. Behind the panel the driver needs about 75 mm of clear depth for the basket and the 81 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, and tighten the fixings evenly and only enough to seal so the frame is not distorted. 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.
