Aluminium-manganese tweeter system

The tried and tested aluminiummanganese tweeter system transmits music signals up to 40,000 Hz. A transmission front plate made of aluminium acts as a wave guide and supports the dispersion characteristics of the system.


Titanium membranes

In the new Chrono SL Series both the woofers and mid-range speakers have titanium membranes. In combination with the latest generation of the triple-fold wave surround this gives a controlled, faultless swing-in and swing-out behaviour even at high volume.


Cabinet geometry

The high standards set by the Chrono SL Series are reflected in the elaborate design of the seamless monocoque cabinet. Diamond-cut aluminium rings, an improved HDF cabinet interior with down-fire bass reflex opening, a conical spacer and a solid socket construction combine to set a new trend in design and sound.



The elegant surfaces are lacquered and sealed in an elaborate multistage process. They are available in black and white “high gloss”.




Front cover                   

The high quality, acoustically neutral fabric covers hide the technology from view and can be elegantly attached using magnetic fastenings.
