Cabinet design
Tweeter driver

driver
The box design with a narrow baffle and curved
side is not only an esthetical neat shape, but also
provides some advantages in terms of acoustics,
since non parallel walls
resonances of the cabinet.
The cabinet is made from sturdy MDF board, which
offers good sonic qualities.
The cabinet is further strengthened with bars,
which in total ensures a very stable construction.
We have selected a ribbon tweeter which provides
superior transient response and a very flat fre-
quency response. The ribbon cone is super light
and only 18 microns thick. It is a sandwich con-
struction made from rosin-aluminium-rosin that
has been hardened at 320 degrees Celsius.
The magnet system is a 2 row high-efficient neody-
mium magnets in a moulded chassis of ceramic car-
bon steel.
Fishbone shaped contactors in aluminium, results
in a low connection resistance and good heat distri-
bution.
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 dif-
ferent 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" mag-
nesium driver from the Seas Excel series that have
extreme performance. We claim that finding a bet-
ter 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 surrounding makes sure that no edge
resonances are present.
The moulded metal basket is a "high flow" type that
is acoustically transparent with high precision as
the basket is shaped exactly due to the moulding
process. This makes sure that the basket is very
stable and efficiently reduces resonances. The bas-
ket is absolutely non-magnetic, which contributes
to a higher efficiency of the driver.
A strong magnet combined with the light cone en-
sures a high efficiency and a good transient re-
sponse.
Heavy copper rings mounted above and below the
T-shaped pole piece reduce non linear- and modu-
lation-distortion and increases the overload mar-
gin.
