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.
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.
Gold plated terminals reduce contact resistance
and serves as anti-corrosion.
Large windows in the basket both above and below
the spider reduces sound reflection, air flow noise
and cavity resonances.
Also for the bass register we selected a SEAS driver
of the type coated paper, a very well-tried type with
an unbeatable relation between price/performance.
The coated paper 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.

For the 99.38, we have chosen to have an external
cross over box. Having the cross over outside the
box has some benefits.
1. Less affection of microphonic in the cross
over.
2. Making the assembly easier and
having the opportunity to drive the
speaker fully active.
The components being used in the cross over, are
only of high quality, to get as small affection as
possible on the signal
