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.

K2 S5800 specifications

The JBL K2 S5800 is an exceptional loudspeaker that caters to audiophiles and professional audio engineers looking for high fidelity sound in various listening environments. Known for its iconic design and remarkable performance, the K2 S5800 combines advanced technology with a rich heritage in audio engineering, making it a standout choice in the realm of high-end speakers.

One of the main features of the K2 S5800 is its innovative 3-way speaker configuration, which incorporates a 15-inch woofer, a 4-inch midrange driver, and a 1-inch titanium dome tweeter. This combination allows for a wide frequency response, delivering deep and powerful bass, clear midrange, and crisp high frequencies. The result is a well-balanced sound that can reproduce music accurately without coloration, providing listeners with an authentic audio experience.

The K2 S5800 utilizes JBL's patented Bi-Radial horn technology, which enhances the dispersion of high frequencies across a broad area. This technology ensures that listeners can enjoy consistent sound quality, whether they're positioned in the sweet spot or off to the side. Additionally, the advanced waveguide design of the horn optimizes the interaction between the drivers, further improving coherence in sound reproduction.

Another noteworthy characteristic of the K2 S5800 is its ability to handle high power levels, making it suitable for both home audio systems and professional studio environments. With a power handling capacity of up to 800 watts, the K2 S5800 can deliver powerful sound that fills large spaces without distortion. This capability is crucial for audio professionals who require reliable performance during recording, mixing, or live sound applications.

The speaker's cabinet is meticulously crafted from high-quality materials, providing both aesthetic appeal and acoustic integrity. The enclosure is designed to minimize resonance and unwanted vibrations, ensuring that the sound remains clean and true to the source. Furthermore, the K2 S5800's elegant finish and sleek design add a touch of sophistication to any space, making it not just a high-performance speaker, but also a stylish piece of furniture.

In summary, the JBL K2 S5800 is a remarkable loudspeaker that merges cutting-edge technology with a commitment to audio excellence. With its powerful drivers, advanced dispersion technology, and premium build quality, it is an ideal choice for anyone seeking unparalleled sound performance in a beautifully designed package.
