Description

32cm Subwoofer 4ohm, Sandwich Paper Cone, Ferrite Magnet

The 32W/4878T00 is the most powerful subwoofer designed by Scan-Speak to this date, with its large 3” voice coil, extreme linear excursion and low resonance frequency, it is 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 relatively low weight. The motor system has heavy duty copper sleeves for reducing eddy currents and minimising self-induction.

Features

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