Scan-Speak 18W/4531G01 'Revelator'

Woofer with sliced paper cone, SD-1 motor and large ferrite magnet system.

The slices filled with dampling glue dramatically reduce the break-up modes in the paper diaphragm. In combination with Scan-Speak's low-loss linear suspension and patented Symmetrical Drive (SD-1), the Revelator 18W/4531G01 woofer represents a real breakthrough in midrange clarity and overall smooth frequency response characteristics.
