Cabinet design
Tweeter driver
Woofer/midrange
driver
The box design with a narrow baffle and curved side -
is not only an aesthetically neat shape, but also has
some advantages in terms of acoustics, since
nonparallel walls muffles internal resonances of the
cabinet.
The cabinet is made in sturdy MDF board, which has
good sonic qualities.
The cabinet is further strengthened with bars, which
in total yields a very stable construction.
We have chosen a ribbon tweeter which provides
superior transient response and a very flat frequency
response The ribbon cone is super light and only 18
microns thin. It is a sandwich construction of rosin-
aluminium-rosin that has been hardened at 320
degrees Celsius.
The magnet system is a 2 row high-efficient
neodymium magnets in a moulded chassis of ceramic
carbon steel.
Fishbone shaped contactors in aluminium, yields a
low connection resistance and good heat derivation.
The driver has high power durability and handles
frequencies up to 40000 Hz which makes it DVD-
Audio and SACD-ready.
After evaluating a large number of drivers from
different manufacturers 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
have extreme 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 moulded metal basket of "high flow" type that
is acoustically transparent and high precision since
the basket is shaped exactly due to moulding. This
makes sure that the basket is very stable and
efficiently reduces resonances. The basket is
absolutely none magnetically, which contributes to
a higher efficiency of the driver.
A strong magnet combined with the light cone
yields a high efficiency and a good transient
response.
Heavy copper rings mounted above and below the
T-shaped pole piece reduces non linear and
modulation distortion and increases the overload
margin.
