  • WOOFER 28W/4878T00
    The 28W/4878T00 is a very powerful 28cm sub 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.

    KEY FEATURES:
    · Paper sandwich cone
    · Spider with balanced tinsel leads
    · 3” Voice coil, Titanium former and paper reinforced
    · Patented Symmetrical Drive motor
    · Extreme linear excursion (+/-14 mm)

    · Stiff and strong die cast aluminium chassis
