Description

32cm Woofer 8ohm, Sandwich Paper Cone, Ferrite Magnet

The 32W/8878T01 is the most powerful woofer designed by Scan-Speak. Its large 3” voice coil and low resonance frequency is perfect to reproduce low to mid frequencies with high efficiency. 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 optimising eddy currents effect and minimised self-induction.

Features

  • Paper sandwich cone with Patented foam filling
  • Patented Symmetrical Drive motor
  • Spider with balanced woven in tinsel leads
  • Long linear excursion (+/- 7.5 mm)
  • 3" Voice coil, Titanium former and paper reinforced
  • Stiff and strong die cast aluminium chassis
