Динамик СЧ/НЧ SCANSPEAK 18W/8535-01. Инструкция на английском языке

MIDWOOFER                                                   18W/8535-01
This unit is an improved version of the highly praised 18W/8535-00 midwoofer, where
a new aluminum chassis and an updated cone as wells as a few other details are
introduced, these updates improves mechanical stability and sound performance. High-
quality magnet system design with patented Symmetric Drive(SD-1) continues to be
key feature.
KEY FEATURES:
· Patented Symmetrical Drive Motor Design  · Coated Air Dried Paper/Carbon Fibre Cone
· 38mm Voice Coil                         · Low-Loss linear suspension
· Low Damping SBR Rubber Surround         · Aluminium Chassis
