Description

The WS 25 E 4 Ω is a 25 cm woofer for cabinet construction and replacement-driver projects. Its coated paper cone and rubber surround support a stated excursion limit of ±6 mm. Check the 225 mm cut-out, fixing pattern and enclosure alignment before replacing an existing driver.

Typical applications

  • Bass reproduction in a suitable loudspeaker cabinet
  • Replacement of an electrically and mechanically compatible 4 Ω woofer

Installation and cabinet guidance

Use the manufacturer drawing to confirm cut-out, depth and fixing positions before machining the enclosure.

Connect an amplifier suitable for the stated nominal impedance and observe terminal polarity where marked.

Mount the unit on a rigid, sealed baffle where required and keep drive within the manufacturer's rated and maximum limits.
