WOOFER 22W/8857T00
The Revelator woofers and subwoofers features very rigid cones in paper or aluminium
that operates as a piston over a wide frequency range, in combination with Scan-
Speaks low-loss linear suspension and the patented Symmetrical Drive (SD-1) it
results in very low distortion and a smooth and well behaved frequency response as
well as perfect transient reproduction.

KEY FEATURES:
Patented Symmetrical Drive Motor Design
Low-Loss linear suspension
Die cast Alu Chassis vented below spider
Rigid Black Anodized Alu Cone
Low Damping SBR Rubber Surround
Ferrite Magnet System w. Rubber Boot
