SB Acoustics SB65WBAC25-4 2.5" Fullrange

  • Geometrically furrowed aluminum cone for extended usable frequency range.
  • Copper cap for increased high frequency output, reduced phase shift at higher frequencies and improved power handling capability.
  • Low damping surround and non-conductive voice coil former to ensure dynamics and an open/transparent sound character with excellent detailing/resolution.
  • Linear neodymium motor system for reduced distortion.
  • Vented voice coil former for reduced compression.
