Динамик НЧ SCANSPEAK 32W/4878T00. Инструкция на английском языке

SUBWOOFER                                                  32W/4878T00
The 32W/4878T00 is the most powerful sub woofer designed by Scan-speak to this
date, with its large 3” voice coil, extreme linear excursion and low resonance frequency
is it perfect to reproduce the deepest frequencies. 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 and minimizing self-induction.
KEY FEATURES:
? Paper sandwich cone with Patented foam filling    ? Extreme linear excursion (+/-14 mm)
? Patented Symmetrical Drive motor         ? 3” Voice coil, Titanium former and paper reinforced
? Spider with balanced woven in tinsel leads    ? Stiff and strong die cast aluminium chassis
