HELIX C 2M

These reference speakers in our C-series raise the bar to a new level of fantastic sound quality. The legendary sisal woofer cones are equipped with an additional structural damping layer made of an elastomer, which again improves the acoustic properties of the driver. The tweeter enclosure also underwent a complete overhaul. Anyone who wants to operate these loudspeakers as fully active speakers (e.g. using our new digital signal processors) can put together the system of their choice by combining the individual components.

Features

  • Ultra lightweight silk dome for a distinguished and natural midrange response
  • Sturdy protection grille for protecting the dome from damages
  • 10 x drilled neodymium magnet for highest magnetic flux linearity
  • Integrated, dampened coupling volume for very low resonance frequency
