The 32W/4878T01 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.
