28 cm Woofer, 8 ohm, Sandwich Paper Cone, Ferrite Magnet
The 28W/8878T01 is a very powerful 28cm woofer, with its large 3” voice coil, extreme linear excursion and low resonance frequency is it perfect to reproduce the deepest frequencies. It features a paper-sandwich cone with very high stiffness and relative low weight. The motor system has heavy duty copper sleeves for optimizing eddy currents and minimizing self-induction.
