The HD6 include some pretty significant upgrades over the A5+s.  Among these are:

  • Larger redesigned woofer with die-cast aluminum frame for extended bass response with fast dynamics
  • New larger custom 1” tweeter for an open and realistic high end and an extraordinary soundstage
  • Thicker, low-resonance cabinet
  • Upgraded crossover components

In addition to the performance related upgrades, the HD6s also feature:

  • Bluetooth aptX and digital optical inputs
  • Real wood-veneer cabinet finish options
  • Removable magnetic grills
  • Solid aluminum remote control
