NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL. To prevent the risk of electric shock, do not remove cover or back. No user-serviceable parts inside. IMPORTANT SAFETY INSTRUCTIONS! PLEASE READ THEM BEFORE OPERATING THIS EQUIPMENT. 1. Clean only with a non-abrasive dry soft cloth. [. . . ] The Low Frequency Section of the System consists of three 12 inch Aluminum Cone Woofers capable of long cone excursions. The sound produced has very low levels of harmonic distortion and a frequency response down to 16Hz. They have a large motor assembly made with High Temperature Neodymium magnets with inherent shielding to greatly reduce Figure 3 any external magnetic field. The woofer design also utilizes an aluminum shorting ring and copper capped pole piece. This results in lower distortion due to more linear magnetic flux in the voice coil gap. A good example of this low distortion is incredible smoothness and effortless clarity in the reproduction of the human voice. The Crossover Networks used in the XCS2K Loudspeaker System are phase matched between the Low Frequency, Midrange and High Frequency Sections to ensure a smooth frequency response over the entire audible range. The crossover inductors are selected so they will not add audible distortion. The network capacitors are film type for extra reliability. All the Capacitors and Inductors are chosen for high current capacity. Each section of the network utilizes it own self resetting high current PPTC type fuses to provide an extra measure of protection. Figure 2B 4 Introduction and Performance Features · Shielded Magnetic Field The XCS2K may also be used in Home Theater Installations near a television receiver or monitor without causing the television image to degrade. By design, all of the speaker's magnetic structures are inherently shielded which prevents interference. · Low Harmonic and Intermodulation Distortion The XCS2K Loudspeaker System is capable of reproducing the full dynamic range of a symphony orchestra with very low audible distortion of any kind. Figure 4 · High Power Handling The Loudspeaker Elements and Crossover Components of the XCS2K are all chosen for use with powerful amplifiers up to 2, 000 watts. · Superior Imaging Locating the Tweeters between the two rows of Midranges generates a symmetrical response for superior imaging. · Versatile Operation and Placement In addition to the regular connections, the XCS2K Loudspeaker System provides separate connections for BiAmplification and Tri-Amplification hookups, as well as Bi-Wiring and Tri-Wiring. · Extruded and Machined Side Panels and Column The top and bottom of the XCS2K Low Frequency enclosure and the Midrange/Tweeter Column enclosure are machined from extruded thick aluminum panels to be non-parallel and are given a High Gloss Black Piano Type Finish. · Gold Plated Input Connectors The XCS2K input connectors are gold plated for superior corrosion resistance and high electrical conductivity. Figure 5 Figure 6 Performance Features · High Temperature Neodymium-Iron-Boron Alloy Magnets The 3 twelve inch Woofers, 32 two inch Midranges and 20 three-quarter inch Dome Tweeters all use the NeodymiumIron-Boron magnets. This Alloy has the highest flux density per unit of volume and helps to keep the Loudspeaker System weight to a minimum while preserving the utmost in performance. 5 Dimensions The following dimensions can assist in determining the best location for your XCS2K Loudspeaker System.

The optimal method for selecting all the Loudspeaker Locations in a Home Theater System includes the use of a real time spectrum analyzer operated by an experienced system installer. An uncompromising installation would take into consideration the floor, wall and ceiling coverings, the type and placement of furniture and can even include the architectural design of the room and its construction materials. Place the Loudspeaker in the final location. [. . . ] Connect a Loudspeaker cable from the XCS2K HIGH Frequency INPUTS 3 (+) Binding Post to the (8 ohm) Binding Post C of the Power Amplifier number two. Connect a Loudspeaker cable from the XCS2K MID Frequency INPUTS 2 (-) Binding Post to the (-) Binding Post B of the Power Amplifier number two. 14 Note: It is important to maintain the correct polarity at both ends of the Loudspeaker cables. How to Connect using a three Amplifiers Caution: The AC Power Cord should not be connected to the Power Amplifiers until after the Loudspeaker Connections have been made. Failure to observe this could result in Electric Shock. Follow the connection instructions below, together with the Connection Diagrams located on the separate folded sheet "Mc1A and 1B", as this represents an example of a typical audio system. Your system may vary from this, however the actual components would be connected in a similar manner. [. . . ]
