MIDWOOFER
15W/8530K01
The Revelator midrange and midwoofers, both well known for their sliced paper cone
technology. The slices are filled with damping glue, which dramatically reduces break-
up modes in the diaphragm. In combination with Scan-Speaks low-loss linear
suspension and the patented Symmetrical Drive (SD-1) it represented a breakthrough
in midrange clarity and overall smooth frequency response characteristics.
KEY FEATURES:
Patented Symmetrical Drive Motor Design
Coated Paper Cone
Low Damping SBR Rubber Surround
Sliced Cone (Controls Cone Breakups)
Low-Loss linear suspension
Die cast Alu Chassis vented below spider
