ScanSpeak 18W, 8535-01 MidWoofer - Classic Range

This unit is an improved version of the highly praised 18W/8535-00 midwoofer, where a new aluminum chassis and an updated cone as wells as a few other details are introduced, these updates improves mechanical stability and sound performance. Highquality magnet system design with patented Symmetric Drive(SD-1) continues to be key feature.

This is the replacement for the 18W, 8535-00 Driver.
