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
