Scanspeak 18WU/8747T00 Illuminator 18cm 8 Ohm woofer. A radical rethink in speaker design.
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.
- Under-Hung Neodymium Motor Design
- Black Anodised Aluminium Alloy Cone
Exceptionally Long Linear Excursion
- Patented Symmetrical Drive (SD-3)
- Low-loss linear suspension
