ScanSpeak 15W, 8531K00 MidWoofer - Revelator Range

ScanSpeak 15W, 8531K00 MidWoofer - Revelator Range

Revelator midwoofers are famous for their Scanspeak Sliced Paper Cones, the slices are filled with damping glue. The effect is to reduce break-up nodes in the 6" cone, and give a midrange clarity and overall smooth frequency response which has made this top audiophile range uniquely successful.

Die cast Aluminum Chassis vented below spider.

Low Loss linear suspension, large ferrite magnet system and a high output. Symmetrical Drive Motor System, Low Damping SBR Rubber Surround.
