It represents the sum total of our research and developmental efforts in sound reproduction over the last half century. We have labored to create a loudspeaker system with no acoustical or electrical limitations whatsoever. While the Project K2 S5800 loudspeaker is itself a new development, the goal behind it goes right back to the earliest days of the original James B. [. . . ] Ideally, any listening room should contain a combination of live surfaces (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 surface has an absorbent covering. With Project K2 S5800, it is most important to be able to accommodate 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. 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 feature 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. Allow enough clearance between the back of each speaker and the wall to allow making the connections 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 supporting 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 system, 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. 12 Figure 7. Room placement of K2 S5800 speaker system.

In this event, consult your Project K2 S5800 specialist dealer for assistance. If, however, the problem has moved to the other speaker, then the cause is in either a cable or an electronic component. IF THE SYSTEM PLAYS AT LOW VOLUMES BUT SHUTS OFF AS VOLUME IS INCREASED: IF THE SPEAKERS SOUND QUALITATIVELY DIFFERENT IN AN INDEFINABLE WAY: · Test the batteries and replace them if necessary. NOTE: The batteries should be tested once a year in any event. · Check the "Balance" control on your receiver/processor. [. . . ]
