Динамик НЧ SCANSPEAK 22W/8851T00. Инструкция на английском языке

WOOFER                                                     22W/8851T00
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 low-loss 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    ? Rigid Paper Cone
? Low-Loss linear suspension               ? Low Damping SBR Rubber Surround
? Die cast Alu Chassis vented below spider    ? Ferrite Magnet System w. Rubber Boot
