JBL K2 S5800 manual Placement and Setup Considerations, Floor Requirements

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.
