Scanspeak Illuminator 18WU/8747T00 Woofer

Illuminator 18cm 8 Ohm woofer. A radical rethink in speaker design.

Illuminator logo

This 18cm 8 ohm woofer is the product of many years research at Scanspeak R&D, Videbaek, Denmark and brings together many advancements.

Featuring a unique airflow optimised open chassis and underhung Neodymium SD-3 magnet system, this woofer is free from compression & reflection effects, resulting in highly accurate reproduction. With a rigid aluminium alloy cone, copper capped pole piece & huge linear excursion, this audiophile quality driver operates as a pure piston delivering highly accurate bass reproduction with great authority, extension and texture.

We believe this is possibly the finest 18cm dedicated woofer available. There is a full datasheet at the bottom of this page for download.

Available in 4 and 8 ohms.

Key Features:

    • Under-Hung Neodymium Motor Design
    • Black Anodised Aluminium Alloy Cone
    • Exceptionally Long Linear Excursion
    • Patented Symmetrical Drive (SD-3)
    • Low-loss linear suspension
