ScanSpeak 15W, 8530K01 MidWoofer - Revelator Range

Replacement for the Ruark Solus bookshelf speaker woofer.

Revelator mid-woofers 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 the spider.

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