The low frequency section interfaces
with the external main control panel for
input connections and switch functions.
They also employ massive air core
inductors for best possible sonic char-
acteristics and lowest possible col-
o r a t i o n .
All internal connections are of propri-
etary Monster Cable
®
, and all critical
connections are gold plated for long
life. Capacitors are ultra high grade
mylar for extremely low loss, and are
bypassed with polypropylene for
improved transient behavior. Network
plates and the port bezels are metal to
eliminate vibration and help conduct
unwanted heat away from the network.
All switches and components are of the
highest quality for long life and
reduced distortion of all types.
The network also utilizes JBL’s propri-
etary Charge-Coupled topology, which
e f fectively "charges" the network at all
times so that all components are con-
stantly on and do not have to generate
distortion while switching between on
and off stages. This is accomplished by
a battery that biases the components in
the network.
The network also facilitates bi-amping
and bi-wiring as necessary, using con-
figuration switches and twisted pair
j u m p e r s .
The HF level control allows fine tuning
of the high frequency output level to
the acoustics of the listening space as
well as to the listener’s liking.
ADamping (Q) Adjustment knob is
also provided to fine tune the interac-
tion of the low frequency section of the
K2 S9800 with the power amplifier in
u s e .
E x t e rnal Connections
The input connectors provide for both
bi-amplification and bi-wiring, which
are explained in detail later in this
g u i d e .
E n c l o s u re s
The enclosure design of the P roject K2
S 9 8 0 0 minimizes coloration by dramat-
ically reducing panel radiation. It is
constructed from 25 mm (1 inch) thick
MDF and SonoGlass™ panels.
The enclosure's unusual thickness,
along with the SonoGlass™ panels,
add up to the lowest vibration, most
acoustically inert loudspeaker enclosure
presently possible to construct.
Enclosures are finished with a high-
gloss polyurethane lacquer.
Base and Fe e t
P ro j e c t K2 S9800 terminates in a mas-
sive base consisting of 3 layers of dif-
ferent panels along with specially
designed stainless steel spiked feet.
All unwanted mechanical vibration is
channeled down via the point-to-point
e n e rgy transmission system and dissi-
pated into the base, which is massive
enough to couple acoustically to the
floor and therefore the dwelling sub-
s t r u c t u r e .
