  • Page 6: Preface

    JBL engineers have labored to create a loudspeaker system with no acoustical or electrical limitations whatsoever. While the Project K2 S9900 is itself a new development, the goal that it achieves goes back to the earliest days of the original James B. Lansing Sound Company.
  • Page 7 Autogoods “130”...

  • Page 8: Legacy

    At JBL, Inc., this has happened eight times. In each case, JBL engineers were told to build the speaker system they had always wanted to build. Whatever resources were required would be made available.
  • Page 9 Most important, it was the first loudspeaker system available to consumers to do all this. Project K2 S9900, one of the most advanced and sophisticated loudspeakers in the world today, is the latest expression in technology that is deeply rooted in more than 60 years of tradition.
  • Page 10 In overall dynamics and transient response, transducers became once again a potentially weak link in the high-end audio reproduction chain. It was in this environment that JBL engineers set out to create the fourth and fifth Project loudspeakers, K2 S9500 and K2 S5500. As with the Hartsfield, the simplicity of a two-way system was considered the most promising design track.
  • Page 11 The K2 S9900 continues the tradition of the K2 S9800 and also incorporates key design elements from the DD66000. Despite its 21st century power and sophistication, Project K2 S9900 is a synthesis of tradition and technology. It reflects the design, material, engineering and manufacturing expertise developed and refined through nearly six decades of experience that are the exclusive legacy of one loudspeaker brand –...

    Project K2 S9900 CHAPTER 2 The Project K2 S9900 Loudspeaker – a Triumph in Acoustics and Technology The following sections describe the primary features and components of the Project K2 S9900 loudspeaker system. The basic system configuration is what has been referred to historically as an augmented two-way.
  • Page 13 The transducers, horns and crossover networks are housed in a visually stunning enclosure that is reminiscent of both the DD66000 and K2 S9800 systems. The specially curved baffle provides the sidewalls for the main horn. The top and bottom horn flares are accomplished by the attachment of precision-molded ®...

  • Page 15 This material is insensitive to temperature changes and back EMF from the coil. JBL engineers have overcome the tendency of alnico to demagnetize with high drive, by utilizing a massive shorting ring at the base of the motor assembly. The top plate is constructed of alternating copper-steel laminations.
  • Page 16 This fully vented frame and motor design also serves to minimize the back pressure under the dome and spider, helping to reduce harmonic ™ distortion to even lower levels. Proprietary JBL Vented Gap Cooling (VGC) is incorporated within the motor structure, and lowers the operating temperature of the coil during moments of high-power operation.
  • Page 17 The phasing plug is a traditional JBL rapid-flare, coherent-wave four-slot design. This coherent-wave design shapes the wave output, producing a truly coincident wave front as the sound enters the Bi-Radial horn. The diaphragm is formed of magnesium-alloy foil and is the first JBL large-format 100mm compression driver to use this special material.

  • Page 20 Project K2 S9900 Internal Crossover Network The circuit topology, combined with the acoustic behavior of the 1500AL-1 and 476Mg, provides a 24dB-per-octave transition at 900Hz. This is the primary crossover point of the system. Additionally, the 045Be-1 is turned on above 15kHz to provide extended response to beyond 50kHz.

    Project K2 S9900 system. Because of the bulk and weight of this loudspeaker, it is recommended that at least two people unpack it in the following manner.

  • Page 24: Chapter 4 Selecting Cable

    Project K2 S9900 CHAPTER 4 Selecting Cable Speaker wire and interconnecting cables are important components in any audio system. With a system such as the K2 S9900, they assume a new level of importance. The K2 S9900 loudspeakers are internally wired with high-quality oxygen-free copper cables.

  • Page 26: Chapter 5 Amplifier Recommendations

    Project K2 S9900 CHAPTER 5 Amplifier Recommendations No single type of amplifier is specified for use with the Project K2 S9900 system. The speakers are highly efficient and will operate adequately with an amplifier or receiver of 70–100 watts. However, the transient response and audio definition of a high-end system such as the K2 S9900 will pick up all the inefficiencies and distortion in an amplifier system.

  • Page 28: Chapter 6 Placement And Setup Considerations

    CHAPTER 6 Placement and Setup Considerations The Project K2 S9900 loudspeaker system is designed to be less affected by room acoustics than conventional imaging systems. However, it is still sensitive to overall symmetry and proximity to walls, ceilings and corners.
  • Page 29 • The surrounding environment for the speakers affects bass quality. Placing the speakers closer to the wall behind them or to the side walls will result in an abundance of bass, but placing them too close will result in dull bass. On the other hand, too much distance will reduce the bass output but result in fast and sharp bass.

  • Page 30: Chapter 7 Switch Operations

    Project K2 S9900 CHAPTER 7 Project K2 S9900 Switch Operations In addition to the input binding posts and connecting straps on the die-cast input plate, the K2 S9900 has two level-adjustment controls, a bi-amp switch and a 9V battery for biasing the signal capacitors. The battery is mounted under an access cover which is held in place by two Phillips-head screws.
  • Page 31 Presence Level This switch adjusts the attenuation applied to the 476Mg driver by approximately 0.3dB over the range of 1,500Hz to 3,000Hz. The vocal presence range is made softer by reducing the level and stronger by increasing the level. This action is accomplished by trimming attenuation resistors.
  • Page 32 K2 S9900 system. Battery Installation The network of this system utilizes the proprietary JBL “charge-couple method” to activate capacitors by applying DC bias using battery power; this eliminates unwanted distortions. Please refer to procedures below and install the supplied battery in the battery holder.
  • Page 33 to each of the capacitor positions in the various networks. The biasing of the capacitors is done through a large value resistor (2.2 megohm) and thus draws no appreciable current. The expiration date printed on the battery generally coincides with the need to replace the batteries. Each capacitor position is actually made up of two capacitors connected in series.

  • Page 34: Chapter 8 Connections

    Project K2 S9900 CHAPTER 8 Project K2 S9900 Connections Caution: Turn all amplifiers off before connecting or disconnecting the K2 S9900 loudspeakers. Making connections while an amplifier is operating could seriously damage the loudspeaker system and void the warranty. All amplifiers must also be turned off before connecting or disconnecting cables at the amplifier or preamplifier inputs.
  • Page 35 I. Passive Connection Method The passive method requires one amplifier and one set of wires. Connections are made to either the upper terminals or the lower terminals. Do not remove the shorting straps. II. Bi-Wire Connection Method The bi-wire connection method requires one amplifier and two sets of speaker wires.
  • Page 36 Project K2 S9900 K2 S9900 is shipped with a twisted pair of shorting straps installed. In case the bi-wire or bi-amp connection method is to be employed, remove the straps from the terminals (referring to Figure 13) and retighten the terminals. If the ampli-...

    CHAPTER 9 K2 S9900 Care and Maintenance The Project K2 S9900 loudspeaker system requires no maintenance other than occasional dusting with a soft, dry, lint-free cotton cloth. The horns may also be wiped with a soft cloth. Treat the lacquered surface very carefully to avoid scratching the finish.
