Scanspeak 15W-8530K00 User Manual [ru]

MIDWOOFER 15W/8530K00

The Revelator midrange and midwoofers, both well known for their sliced paper cone
technology. The slices are filled with damping glue, which dramatically reduces break­up 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

· Low-Loss linear suspension

· Coated Paper Cone

· Sliced Cone (Controls Cone Breakups)

· Low Damping SBR Rubber Surround

· Large Ferrite Magnet System
