045TI PURE-TITANIUM
DIAPHRAGM/
NEODYMIUM MAGNET
ULTRAHIGH-FREQUENCY
COMPRESSION DRIVER
See Figure 5.
The 045Ti utilizes the same princi-
ples as the 435Al, in a smaller foot-
print so that a frequency response
up to 40kHz can be achieved.
INTERNAL CROSSOVER
NETWORK
Each loudspeaker unit has two
internal dividing networks, one for
the LF transducers and one for the
combined HF and UHF transducers.
The low-frequency section inter-
faces with the external main con-
trol panel for input connections and
switch functions. They also employ
massive air core inductors for best
possible sonic characteristics and
lowest possible coloration.
All internal connections are of pro-
prietary Monster Cable
®
, and all
critical connections are gold-plated
for long life. Capacitors are ultra-
high-grade polypropylene for
extremely low loss. Network plates
and the port bezels are metal to
eliminate vibration and help con-
duct unwanted heat away from the
network. All switches and compo-
nents are of the highest quality for
long life and reduced distortion of
all types.
The network also utilizes JBL’s pro-
prietary Charge-Coupled Linear
Definition
™
topology, which effec-
tively “charges” the network at all
times so that all components are
constantly on and do not generate
distortion while switching between
the on and off stages. This is
accomplished by a battery that
biases the components in the net-
work. The network also facilitates
bi-amping
and bi-wiring as neces-
sary, using a configuration switch
and shorting bars.
The HF level control allows fine-
tuning of the high-frequency output
level to the acoustics of the lis-
tening space as well as to the
listener’s liking.
EXTERNAL
CONNECTIONS
The all-metal, gold-plated, 5-way
binding-post input connectors pro-
vide for both bi-amplification and
bi-wiring, which are explained in
detail later in this guide.
ENCLOSURES
The enclosure design of the
Project K2 S5800 minimizes col-
oration by dramatically reducing
panel radiation. It is constructed
from 1-inch (25mm)-thick MDF.
The enclosure’s unusual thickness,
along with the SonoGlass horn
assembly, add up to the lowest
vibration, most acoustically inert
loudspeaker enclosure presently
possible to construct. Enclosures
are finished with a high-gloss
polyurethane lacquer.
