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.
