IW 406 FG II Installation speaker

The IW 406 FG II uses a 6.5-inch woofer and a 1-inch titanium dome tweeter to deliver remarkably accurate sound, tailored to its in-wall design. SoundAngle technology allows you to fine tune the IW 406 FG II to the listening area and to the most discerning tastes.

  • A redesigned magnetic paintable grille with a new, more natural white color to blend seamlessly into any premium decor
  • Jamo core technology created for clear, detailed sound and zero distortion
  • Decoupled Tweeter Technology (DTT) minimizes vibration transfer from the baffle to the tweeter for detailed, clear high frequencies
  • Wave Guide provides focused, dynamic transfer of high frequencies into the listening space
  • Hard Conical Cone (HCC) minimizes woofer break-up for punch, clear low frequencies
  • Centre plug replaces the traditional dust cap for cooler voice coil and higher power handling
