(Bi-Wire or Bi-Amp Connection Method)

BI-WIRE CONNECTION METHOD

The bi-wire connection method requires one amplifier and two sets of speaker wires. By removing the shorting bars, connections may be made to the individual network sections using four conductors, one for each of the four terminals (see Figures 10, 12 and 13).

BI-AMP CONNECTION METHOD

The optimal method of powering the Project K2 system is with two amplifiers, one for the low- frequency and one for the high- frequency unit, and a crossover network. Since each amplifier drives only one speaker, this method allows the user to select amplifiers with the desired sonic character for low and high fre- quencies (see Figures 10, 12 and 13).

Four identical amplifiers (or two dual channel units) may be used, although specialized low- and high-frequency amplifiers offer clear advantages. The Project K2 specialist dealer can recommend the amplification that will best suit individual needs.

In all cases, the left and right amplifiers for each section must be identical. Make sure that the input sensitivity of the amplifier for each section is equal, or that input level controls are provided to maintain the proper low-to-mid/high bal- ance. If two identical stereo ampli- fiers are used, one may be located near each loudspeaker and drive low- and high-frequency sections through short wire runs.

NOTE: Input polarity must be the same for both the low- and high- frequency sections. Some ampli- fiers invert polarity. If the polarity is reversed to one section, a discon- tinuity in response will be apparent in the crossover region. If a prob- lem is suspected, reverse the polarity to either low- or high- frequency sections of both loudspeakers. Amplifier polarity markings may not ensure correct polarity connections.

THE WOOFER GRILLE:

The grilles on the Project K2 S5800 loudspeaker system have been designed for maximum acoustical transparency. For the most critical listening, however, JBL suggests removing the grilles. The grilles are connected by four pins inserted into four holes on the face of

the cabinet.

To remove each grille, hold the grille edges with your fingers and gently pull the grille away. Do not use any tools to pry the grille off; this will damage the finish of the cabinet. To replace the grille, posi- tion the mounting pins over the holes and gently press until the grille meets the enclosure.

PROJECT K2 FINAL CHECKLIST

•Connect and plug in all other system electronics.

•Check all connections. If bi- amping or bi-wiring, make sure both shorting bars are removed.

•Make sure the controls on the crossover panel are correctly set.

The system is now ready for use. The Project K2 S5800 speaker system is fully functional as soon as it is set up. The amplifier power should not exceed 300 watts (RMS). There may be some subtle tonal changes in bass output over the first week to 10 days of operation. These are caused as the move- ment of the low-frequency drivers becomes more fluid and the parts settle in. This process is completely normal with transducers of

this caliber.

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. Whether for professional use or high-end home listening, the K2 S5800 exemplifies JBL's legacy of innovation and quality in the audio industry.
