Detailed instructions for use are in the User's Guide.

[. . . ] 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 168 pounds (76. 2 kgs). It requires three or more persons to safely move the Loudspeaker. Thank You Your decision to own this McIntosh XRT1K 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 less volume compression due to improved heat transfer through the sleeves and a cooler operating voice coil. Both measurements, as well as critical Figure 4 listening, reveal ten times less distortion than LD/HP previous designs. A good Conventional example of this low distortion is incredible smoothness and clarity in the reproduction of the human voice. The Crossover Network used in the XRT1K Loudspeaker System is designed Figure 5 to ensure an even frequency response over the entire audible range. The Network utilizes both Second and Third Order design utilizing Capacitors and Inductors with high current Figure 6 capacity. There are two different types of low loss (DCR) Inductors in the network, each one chosen not to exhibit any core saturation even at high power levels. This prevents the addition of distortion to the music at any frequency. The Capacitors used include low loss (ESR) Polypropylene and Mylar types. The Network also utilizes 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 44 two inch Midranges and 28 three-quarter inch Dome Tweeters all use this Alloy. The Neodymium-IronBoron Alloy has the highest flux density per unit of volume and helps to keep the Column weight to a minimum. Figure 7 · Low Harmonic and Intermodulation Distortion The XRT1K Loudspeaker System is capable of reproducing the full dynamic range of a symphony orchestra with very low audible distortion of any kind. · Large Long Low Frequency Port The XRT1K Loudspeaker System utilizes a very large 6 inch diameter port to increase bass output, reduce distortion and improve the overall efficiency of the Loudspeaker. Figure 8 · High Power Handling The Loudspeaker Elements and Crossover Components of the XRT1K 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 horizontal polar response for superior imaging. Figure 9 self resetting high current Poly-Switches to provide an extra measure of protection. The Loudspeaker System utilizes a massive extruded aluminum enclosure that houses the Loudspeaker Drivers. It also has multiple front to back internal braces to form a dampened rigid Column Structure. The Column's small footprint allows for a variety of different placements in a room. Figure 10 · Versatile Operation and Placement In addition to the regular connections, the XRT1K Loudspeaker System provides separate connections for BiAmplification and Tri-Amplification hookups, as well as Bi-Wiring and Tri-Wiring. · Extruded Column The Column enclosure is extruded thick aluminum construction with non-parallel internal sides and is given a High Gloss Black Piano Type Finish. Unpacking the Loudspeaker To protect the fine finish of the XRT1K Loudspeaker System during the installation process, it is advisable to prepare a suitable adjustment area. A freshly vacuumed carpeted area covered with a soft, clean fabric, such as a large bed linen or blanket would be suitable.
