Scan Speak 32W/4878T01 Woofer 32cm (13") with cellulose sandwich cone and aluminum basket

The 32W/4878T01 is the most powerful woofer designed by Scan-speak. Its large 3" voice coil and low resonance frequency are perfect for reproducing midrange-bass frequencies at high efficiency. It is equipped with a brand new paper-sandwich cone type with a special patented foam filling technology that gives the cone very high rigidity and relatively low weight. The motor system is equipped with copper sleeves to optimize eddy current effects and minimize self-inductance.

32W/4878T01 Features

  • 32 cm woofer
  • 4 ohm, sandwich paper cone, ferrite magnet
  • Sandwich paper cone with patented foam filling
  • Patented symmetrical pull motor
  • Spider with balanced tinsel-woven conductors
  • Maximum excursion (±7.0 mm) at high efficiency
  • 3" voice coil, CU wire on titanium support
  • Rigid and robust frame in die-cast aluminum
