WOOFER 32W/4878T01 The 32W/4878T01 is a 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 ? Lin. excursion (±7.0 mm) with high efficiency ? Patented Symmetrical Drive motor ? 3” Voice coil, Titanium former and paper reinforced ? Spider with balanced woven in tinsel leads ?
