HELIX C 1T 25mm tweeter

The C-Series reference loudspeakers raise the bar for fantastic sound quality to a new level. The tweeter housing has been completely redesigned. Those who wish to operate their loudspeakers fully actively (e.g., via one of our digital signal processors) can assemble their desired system from the individual components as desired.

Features

• Particularly lightweight silk dome for outstanding and natural high-frequency reproduction
• Stable grille for optimal protection of the dome against damage
• 12-hole neodymium magnet for optimally linear magnetic flux
• Integrated, damped coupling volume for a particularly low resonant frequency
