CABINETS
To ensure the best possible appearance, the
surface of the aluminium line is treated with the
highest grade of aluminium processing.
After being precisely machined and CNC milled,
all aluminium parts are bead blasted and
transparently anodized.
To maximize internal volume, we profited from
the stiffness of aluminium to realize a slim walled
cabinet. Furthermore, the aluminium panels are
curved to optimize both stiffness and freedom
from resonance, which is so crucial for natural
sound. This curve means that while the average
depth of the speaker is 50 mm (2 inches), it
reaches a maximum point of 84 mm (3.3 inches)
in the center of the arch.
The extra available space in the middle of the
cabinet allows for the use of physically deeper
pure
high-end mid-bass drivers. An additional benefit
of the speakers´ shape is the lack of parallel
walls,
which avoids internal standing waves from
adver-sely affecting performance.
In extensive research we found out that it is vital
not to use a single enclosed form in creating the
box, but to break the cabinet into two separate
elements connected by MDF, with additional dam-
ping strips between the MDF and the aluminium,
in
order to completely eliminate deleterious cabinet
resonance.
