The 32W/8878T01 is a powerful woofer designed by Scan-speak. Its large 3” voice coil and low resonance frequency is it perfect to reproduce low to mid frequencies 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 and minimizing self-induction.
KEY FEATURES: - Paper sandwich cone with Patented foam filling - Patented Symmetrical Drive motor - Spider with balanced woven in tinsel leads - Linear excursion (+/-7 mm) with high efficiency - 3” Voice coil, Titanium former and paper reinforced - Stiff and strong die cast aluminium chassis
