Illuminator 18cm 4 Ohm woofer. A radical rethink in drive unit design.

Illuminator logo

This 18cm 4 Ohm woofer is the culmination of many years research at Scanspeak R&D, Videbaek, Denmark and brings together a host of advancements.

Featuring a rigid aluminium alloy cone, copper capped pole piece & huge linear excursion, this audiophile quality driver operates as a pure piston. The unique airflow optimised open chassis and underhung Neodymium SD-3 magnet system define new standards in terms of minimal compression & reflection.

Delivering highly accurate bass reproduction with great authority, extension and texture, we believe this is possibly the finest 18cm dedicated woofer available.

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
