PREF ACE Thank you for selecting a Project K2 S5800 loudspeaker system. 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 elec- trical limitations whatsoever .
CHAPTER 1 – LEGACY : THE HISTORICAL DEVELOPMENT OF THE JBL PROJECT LOUDSPEAKERS Of those few who seek perfection in sound reproduction, only a handful have actually achieved it.
After Project Everest was intro- duced, sound recording and play- back technology underwent a revolution of its own. With the advent of CD, extremely demanding recorded signals had become the rule rat.
In order to re-create the extremely high dynamic range provided by today’ s audio sources, a new low- frequency transducer was used, incorporating a ferrite magnet, 3- inch edge-wound voice coil, and an Aquaplas ™ -coated 12-inch cone made of Kevlar ® composite, a mixture of Kevlar fiber and pulp material that provides increased rigidity .
CHAPTER 2 – THE PROJECT K2 S5800 LOUDSPEAKER: A TRIUMPH IN ACOUSTICS AND TECHNOLOGY The following sections describe the primary features and compo- nents of the Project K2 S5800 loudspeaker system.
frequency drivers, it utilizes forced-air cooling. The entire magnetic structure is attached to a die-cast aluminum-alloy frame. This provides accurate, rigid support for the motor and cone mounting points, as well as doubling as a massive heatsink by providing a huge surface area for heat dissipation.
045TI PURE-TIT ANIUM DIAPHRAGM/ NEOD YMIUM MAGNET UL TRAHIGH-FREQUENCY COMPRESSION DRIVER See Figure 5. The 045T i utilizes the same princi- ples as the 435Al, in a smaller foot- print so that a frequency response up to 40kHz can be achieved.
CHAPTER 3 – UNP ACKING THE PROJECT K2 S5800 SY STEM All components of the Project K2 system have been very carefully packed for maximum protection against damage. As with any superior audio product, it is advisable to keep the original packing materials in case it is necessary to transport the Project K2 S5800 system.
CHAPTER 5 – AMPLIFIER RECOMMENDA TIONS No single type of amplifier is specified for use with the Project K2 S5800 system. The speakers are highly efficient and will operate adequately with an amplifier or receiver of 70–100 watts.
CHAPTER 6 – PLACEMENT AND SETUP CONSIDERA TIONS 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.
CHAPTER 7 – PROJECT K2 S5800 SWITCH OPERA TIONS The K2 S5800 has two switches mounted on the network panel on the rear of the enclosure. The switches are covered by an access plate which is easily removed by unscrewing the two mounting screws. See Figure 8.
¡ Bias Battery: The bias battery supplies constant DC bias to the crossover capacitors, eliminating crossover distortion at zero electric potential. Replace the test battery supplied with your system with a 9-volt, 006P rectangular battery as soon as possible.
15 SHORTING BARS The K2 S5800 is shipped with short- ing bars installed between its low- frequency and high-frequency terminals. Please see Figure 10. To prepare the K2 S5800 for bi-wire or bi-amp operation, these bars must be removed by completely unscrewing each binding post, removing the bars, and replacing the binding posts.
16 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).
CHAPTER 8 – PROJECT K2 S5800 CARE AND MAINTENANCE The Project K2 S5800 loudspeaker system is sprayed in a poly- urethane finish and requires no maintenance other than an occa- sional dusting with a soft, dry , lint- free cotton cloth. The horns may also be wiped with a soft cloth.
CHAPTER 9 – TROUBLESHOOTING AND SERVICE GUIDE Project K2 S5800 loudspeakers are designed to provide years of trouble-free service. If you are experiencing difficul- ties, we suggest you check these possibilities before contacting your Project K2 specialist dealer for assistance.
