CHAPTER 6 – PLACEMENT AND SETUP CONSIDERATIONS

The Project K2 S5800 loudspeaker system is designed to be less affected by room acoustics than conventional imaging systems. However, it is very sensitive to overall symmetry, and proximity to walls, ceilings and corners.

Ideally, any listening room should contain a combination of live sur- faces (e.g., walls and windows) and absorbent surfaces (e.g., drapes, carpets, upholstery). If the distance from floor to ceiling is short, it is preferable that one sur- face has an absorbent covering. With Project K2 S5800, it is most important to be able to accommo- date the optimum listening area that is defined by the 60° horizontal/ 30° vertical coverage pattern of the horn.

The listener should be centered in front of the speakers and furniture should be of an appropriate height so that when the listener is sitting, the ear level is on a vertical plane with the horn (approximately 32 in/ 80cm) as illustrated in Figure 2.

CAUTION: Project K2 S5800 is a massive system comprising materials chosen for their density, with its weight concentrated in a relatively narrow area. Verify the integrity of

the floor surface before placing and setting up the speakers. See Floor

Requirements.

If possible, the distance between the speakers should be the same as the distance between each speaker and the listening area. Angle the speaker in toward the listener so that when seated, the listener could look straight into the center of the speaker (Figure 7). As the distance increases between the speakers, increase the inward angle of the speaker.

The imaging qualities enable the speakers to be placed relatively far apart from each other. In addition, the low-frequency alignment fea- ture enables placing the speakers near or even in a corner without producing an overabundance of bass. This corner placement ability allows optimum performance even in small rooms.

The Project K2 S5800 system can operate fairly close to the wall. Allow enough clearance between the back of each speaker and the wall to allow making the connec- tions on the back of the speaker (approximately 2"–3" is sufficient), and to avoid interference with the performance of the tuned port.

Remember that these speakers weigh close to 185 lb (84kg) each and cannot be easily moved.

FLOOR REQUIREMENTS

The floor in the location selected for setting up the Project K2 S5800 speakers must be capable of sup- porting a load of 185 lb (84kg). Because of the coupling effect of the stainless steel feet, a flat, hard surface such as wood or linoleum is preferable. However, the design of the loudspeaker’s coupling sys- tem, along with the speaker’s extreme weight, should result in excellent performance on any surface, even on carpets.

To prevent indentations on wood or linoleum floors caused by the weight of the loudspeaker, always utilize the enclosed coasters. Do not set up the Project K2 S5800 system directly on a ceramic tile floor; the concentrated weight might cause the tiles to crack.

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.
