HT CHANNEL APPLICATIONS ONLY FOR REAR CHANNEL APPLICATIONS WE RECOMMEND USING A NILES HDFX OR CM6HDrx LOUDSPEAKER PLACING THE HDLCR AS THE FRONT LEFT AND RIGHT SPEAKERS In a home theater the intelligibility of dialog and action reproduced by the front speakers is paramount The position of the speakers plays a very important role in how clear the sound is and how a stereo image is created Here are some guidelines to make the process of placement quick and easy e Make sure the sound will not be blocked or reflected off furniture or other objects The listener should have a direct line of sight with the front of the speaker To determine the best position measure the listening distance between the ideal listening position e g favorite chair or couch and the wall in which you plan to install the speakers e For stereo music applications try to place the speakers so that they are equally distant from the listening spot and at least one half of the listening distance apart to maintain a large pleasant stereo image e In home theater applications where there is a center channel you may choose to space the left and right main speakers farther apart for a bigger than life sound with Dolby encoded movies and TV shows However for combined music and movie usage we recommend using the placement zone for stereo music Ideally if the listening position is 10 feet back from the wall place the speakers between 5 and 10 feet apart
