WOOFER 32W/4878T00

The 32W/4878T00 is the most powerful sub woofer designed by Scan-speak to this date, with its large 3” voice coil, extreme linear excursion and low resonance frequency is it perfect to reproduce the deepest frequencies. 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.

Key features:
  • Paper sandwich cone with Patented foam filling
  • Patented Symmetrical Drive motor
  • Spider with balanced woven in tinsel leads
  • Extreme linear excursion (+/-14 mm)
  • 3” Voice coil, Titanium former and paper reinforced
  • Stiff and strong die cast aluminium chassis
