User manual MCINTOSH XCS1K CENTER CHANNEL LOUDSPEAKER

[. . . ] Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment. WAR NING: When this Loudspeaker is connected to an amplifier that is Powered On, the connection terminals may have hazardous live voltages present with a risk of electric shock. CAUTION: When this Loudspeaker is assembled it weighs 133 pounds (60. 3 kgs). It requires two or more persons to safely move the Loudspeaker. Thank You Your decision to own this McIntosh XCS1K Loudspeaker System ranks you at the very top among discriminating music listeners. [. . . ] This results in lower distortion due to more linear magnetic flux in the voice coil gap. Additional benefits are Figure 3 less volume compression due to improved heat transfer through the sleeves and a cooler operating voice coil. Both measurements, as well as critical listening, reveal ten times less distortion than previous designs. A good example of this low distortion is incredible smoothness Figure 4 and clarity in the reproduction of the human voice. The Crossover Networks used in the XCS1K Loudspeaker System are phase matched between the Low Frequency, Figure 5 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. All the Capacitors and Inductors are chosen for high current capacity. Each section of the network utilizes its own self resetting high current PPTC type fuses to provide an extra measure of protection. Figure 2B The Low Frequency Section of the System consists of two 10 inch Woofers. They have a large magnet assembly and long cone excursions with very low levels of harmonic distortion and frequency response down to 16Hz. The Woofer also incorporates McIntosh's Patented LD/HP1 Magnetic Circuit Design. No 5, 151, 943 4 Introduction and Performance Features Performance Features · Patented LD/HP Technology The McIntosh Low Frequency Loudspeaker Elements feature the patented LD/HP Magnetic Circuit Design. This design, when compared to conventional Loudspeaker Elements, reduces distortion significantly. · Neodymium-Iron-Boron Alloy Magnets The 32 two inch Midranges and 20 three-quarter inch Dome Tweeters all use this Alloy. The NeodymiumIron-Boron Alloy has the highest flux density per unit of volume. The smaller overall size of the Midrange and Tweeter Loudspeakers allows for closer spacing and results in improved sound reproduction. · Low Harmonic and Intermodulation Distortion The XCS1K Loudspeaker System is capable of reproducing the full dynamic range of a symphony orchestra with very low audible distortion of any kind. · High Power Handling The Loudspeaker Elements and Crossover Components of the XCS1K are all chosen for use with powerful amplifiers up to 1, 200 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 XCS1K Loudspeaker System provides separate connections for Bi-Amplification and Tri-Amplification hookups. · Extruded Column The top, bottom and rear of the XCS1K Low Frequency enclosure is extruded thick aluminum construction with non-parallel internal sides and is given a High Gloss Black Piano Type Finish. Figure 8 Figure 6 Figure 7 · Gold Plated Input Connectors The XCS1K input connectors are gold plated for superior corrosion resistance and high electrical conductivity. 5 Dimensions The following dimensions can assist in determining the best location for your XCS1K 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.
