Динамик СЧ/НЧ SCANSPEAK 18W/4531G01. Инструкция на английском языке

MIDWOOFER                                                  18W/4531G01
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    ? Sliced Cone (Controls Cone Breakups)
? Wood Fibre Cone                          ? Low-Loss linear suspension
? Low Damping SBR Rubber Surround          ? Large Ferrite Magnet System
