ScanSpeak 26W, 4867T00 Woofer - Revelator Range

4 Ohm 10" unit. Die-Cast Aluminum Chassis vented below spider. Low Damping SBR Rubber surround, Low Loss linear suspension, rigid black anodised aluminium cone, large Rubber Boot ferrite magnet system and a high output.

Revelator woofers are drive units that feature very rigid paper or aluminium cones with a strong wide frequency pure piston action. Powered by the Symmetrical Drive SD-1 Motor design, a low-loss linear suspension, the combination gives very low distortion and a famously smooth frequency response which has made this top audiophile range uniquely successful.
