Динамик НЧ SCANSPEAK 23W/4557T02. Инструкция на английском языке

SUBWOOFER                                                  23W/4557T02
The Revelator woofers and subwoofers features very rigid cones in paper or aluminium
that operates as a piston over a wide frequency range, in combination with Scan-
Speaks linear suspension and the patented Symmetrical Drive (SD-1) it results in very
low distortion and a smooth and well behaved frequency response as well as perfect
transient reproduction.
KEY FEATURES:
? Patented Symmetrical Drive Motor Design    ? Black Anodized Rigid Alu Cone
? Long Throw Surround                      ? Die cast Alu Chassis vented below spider
? Ferrite Magnet System w. Rubber Boot     ? Gold Binding Post Terminals
