2 Installation The following instructions are for installing the XLS320, XLS340, and XCS350 Loudspeaker Systems into the wall using the optional CK320, CK340 and CK350 In Wall Mounting Kits with Grilles. The CK320, CK340 and CK350 Kits share a com- mon mounting procedure with a varying number of mounting brackets and fasteners used to install each Loudspeaker Model. Before proceeding with these instructions refer to the XLS320, XLS340 and XCS350 Owners Manual sections in- cluding Unpacking the Loudspeaker starting on page 10, to Locating the Loudspeaker System on page 18, Tweeter Array Optimization on page 19 and How to Connect starting on page 20, before beginning the Mounting Process. It is recom- mended that the Professionals at your McIntosh Dealer, who are skilled in all aspects of installation and operation, install the Loudspeaker System and any associated audio/video equipment. Caution: Due to the size and weight of the XLS340 and XCS350 Loudspeakers, two or more persons may be required to install them safely. Unpacking the Loudspeaker Unpacking the XLS320, XLS340 and XCS350 Loudspeaker by referring to the instructions contained in the Owners Manual starting on page 10. Then perform the following steps: 1. Place the Loudspeaker System, with the front facing down, on top of the packing material located on top of the shipping carton as illustrated in the Owners Manual. 2. Using the supplied Allen Wrench, re- move the screws at locations illus- trated in figure 1. Note: The XCS350 Loudspeaker requires removal of the Stabilizer Bar and replacement of the three screws used to attach the Stabilizer Bar, with screws of the same type but shorter in length (supplied with the XCS350) to prevent air leaks. Figure 2 Installing the Loudspeaker System The XLS320, XLS340 and XCS350 Loudspeakers Smooth Fre- quency Response may be altered by a large object(s) located in the sound waves path or by locating the Loudspeaker too close to a side wall. There should be an unobstructed area in front of the Loudspeaker of at least 15 degrees either top or bottom from the center axis and 30 degrees side to side for the best performance. Re- fer to figures 2 and 3. 3. Use a suitable wall stud finder or metal detector to verify a proper mounting location for the Loudspeaker System be- fore cutting into the wall. The XLS320 and XLS340 are de- signed for mounting between vertical wall studs with 16 inch (40.64cm) centers. Refer to figure 4. The XCS350 is designed for mounting hori- zontally in a special prepared opening. Refer to figure 5. Note: Make sure there are no Plumbing Pipes, AC Electrical Wiring or Heating/Cooling Ductwork in the wall between the studs where the Loudspeaker is to be mounted. 4. For the XLS320 and XLS340, cut an opening in the existing finished wall using the dimensions in the figure 6 Chart. The In Wall Mounting Bracket(s) can be oriented for anchoring the Bracket to the wall stud either on the left or right hand side of the Loudspeaker. Refer to the Top Inside Views in figures 7 and 8. Note: The In Wall Bracket(s) must be secured to a wall stud on one side, with the other side clamped to the dry wall. In new construction the Loudspeaker Mounting Bracket(s) should be secured to wall studs on both sides. 5.
