Динамик СЧ SCANSPEAK 12M/4631G00. Инструкция на английском языке

MIDRANGE                                                   12M/4631G00
The Revelator midranges are 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 it represented
a breakthrough in midrange clarity and overall smooth frequency response
characteristics.
KEY FEATURES:
? Excellent Midrange reproduction          ? Sliced Cone (Controls Cone Breakups)
? Low-Loss Linear Suspension               ? High Output 89dB @ 2,83V
? Compact Neodymium Magnet System
