TECHNICAL PRESENTATION

CABINET DESIGN
The box design with a narrow baffle - is not only an aesthetically neat
shape, but also offer advantages in terms of acoustics. The cabinet is
made from sturdy MDF board, which offers good sonic qualities.
The cabinet is further strengthened with internal bars, which in total
ensures a very stable construction.
TWEETER DRIVER We have selected a ribbon tweeter which provides superior transient
response and a very flat frequency response. The ribbon cone is super
light and only 18 microns thick. It is a sandwich construction made from
rosin-aluminum-rosin that has been hardened at 320 degrees Celsius.
The magnet system is a 2 row high-efficient neodymium magnets in a
molded chassis of ceramic carbon steel.
Fish-bone shaped contactors in aluminum, results in a low connection
resistance and good heat distribution.
The driver has high power durability and handles frequencies up to
40000 Hz which makes it DVD-Audio and SACD-ready.
WOOFER/MIDRANGE
After evaluating a large number of drivers from different manufacturers
DRIVER we selected one from Seas, a company that has a solid reputation in the
area of high quality speaker drivers. You find Seas drivers in many well-
known High End speakers.
For woofer/midrange we decided on a 6,5" magnesium driver from the
Seas Excel series that has extremely good performance. We claim that
finding a better 6,5" driver on the market is a very difficult task.
The surface treated magnesium cone is extremely light but still
extremely stiff and effectively reduces resonances. The rubber surround
makes sure that no edge resonances are present.
The molded metal basket is a "high flow" type that is acoustically
transparent with high precision as the basket is shaped exactly due to
the molding process. This makes sure that the basket is very stable and
efficiently reduces resonances. The basket is absolutely non-magnetic,
which contributes to a higher efficiency of the driver.
A strong magnet combined with the light cone ensures a high efficiency
and a good transient response.
Heavy copper rings mounted above and below the T-shaped pole
piece reduce non linear- and modulation-distortion and increases the
overload margin.
The copper plating of the top and bottom plates along with a solid
copper phase plug improves the heat conduction and thus contributes
to the high power durability.
Large windows in the basket both above and below the spider reduces
sound reflection, air flow noise and cavity resonances.
