Динамик НЧ SCANSPEAK 32W/8878T01. Инструкция на английском языке

WOOFER                                                     32W/8878T01
The 32W/4878T01 the most powerful woofer designed by Scan-speak. Its large 3”
voice coil and low resonance frequency is perfect to reproduce low to mid frequencies
at with high efficiency. It features a brand new type of paper-sandwich cone with a
special foam filling technology (patented) that gives the cone very high stiffness and
relative low weight. The motor system has heavy-duty copper sleeves for optimizing
eddy currents effect and minimized self-induction.
KEY FEATURES:
? Paper sandwich cone with Patented foam filling    ? Patented Symmetrical Drive motor
? Spider with balanced woven in tinsel leads    ? Long linear excursion (+/- 7.5 mm)
? 3” Voice coil, Titanium former and paper reinforced    ? Stiff and strong die cast aluminium chassis
