Cabinet design

The box design with a narrow baffle and curved
side - is not only an aesthetically neat shape, but
also offers advantages in terms of acoustics, since
nonparallel walls muffles internal resonances of the
cabinet.
Internally the cabinet is physically separated in two
parts, one for the midrange and tweeter, and one
for the woofer. This makes it possible to optimize
the cabinet volume for the woofer.
It also lets the midrange driver to accomplish the
best possible sound without being interfered from
the woofer. The internal boxes have non-parallel
walls.
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 and
to break up standing waves.
Both boxes are filled with a combination of mineral
wool and synthetic damping material, to effectively
reduce internal resonances in the box.
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
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.
