Характеристики

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:

- High-end mid-woofer with sturdy aluminum diecast basket
- Mid-woofer cone with scooped, long-fibered sisal with additional elastomer structural damping
- Virtually compression-free conversion of the amplifier power into sound pressure
- Lowest manufacturing tolerances and exclusive use of selected materials
- Grille included
