DRIVE UNITS BY MANUFACTURER:
This 18cm 4 Ohm woofer is the culmination of many years research at Scanspeak R and 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.
This woofer is 4 Ohms ; the 8 Ohm version is here : 18WU/8747T00
