It requires four or more persons to safely handle the Loudspeaker System. 1. Loudspeaker Cables of adequate size are important to ensure that there will be no significant power loss or heating. Cable size is specified in Gauge numbers or AWG (American Wire Gauge). The smaller the Gauge number, the larger the wire size: If the Loudspeaker Cables are 50 feet (38.1m) or less, use at least 12 Gauge (AWG) wire size or larger. If the Loudspeaker Cables are 100 feet (76.2m) or less, use at least 10 Gauge (AWG) wire size or larger. 2. For additional connection information, refer to the ownersmanual(s) for any component(s) connected to the XRT2K Loudspeaker. 3. The XRT2Ks built-in speaker protection incorporates five automatic resetting solid-state devices in the crossover networks. One protects the tweeters, one for the midranges and three for the woofers. The protection allows a certain amount of overdrive but extended periods will trigger protection. If an obvious lack of high, mid or low frequencies is noticed, the Protection Device may have activated. These devices will automatically reset when the volume level is reduced significantly and kept low until the output of the affected Loudspeaker Element returns to normal. 4. When the XRT2K Loudspeaker System is driven by more than one amplifier, the output levels of the different amplifiers connected to the Loudspeaker System must be adjusted to achieve a proper balance between the low, midrange and high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer. Important Information

11 Room Placement Room Placement Loudspeaker placement in a room can greatly affect performance. The XRT2K Loudspeaker is designed for both Music and Home Theater Systems. The optimal method for selecting speaker locations 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. In those instances where placement in the room is fixed an environmental equalizer may be needed to restore proper musical balance. Placement near a wall, corner, floor, ceiling or any inter- secting surfaces will reinforce some bass frequencies. Which bass frequencies are boosted by placement in a par- ticular location is dependent on the dimensions of the room. Test the various Loudspeaker locations by playing music with continuous bass, setting up the speakers and listening to them from the main listening spot. Move the Loudspeak- ers to an alternate location and repeat the listening, paying attention to how the bass qualities and response levels change. Do not assume the loudest bass is best; rather listen for booming (a lack of articulation), as well as a balance over the whole spectrum, to assure the bass will not drown out the other parts of the music. Experiment with various Loudspeaker positions until the locations that sound best are found. The XRT2K Midrange/High Frequency Columns Smooth Frequency Response may be altered by large ob- ject(s) located in the sound waves path or by locating the column too close to a side wall. There should be an unob- structed area in front of the column of at least 60 degrees either side from the center axis for the best performance. Refer to figure 9. Locating Loudspeakers for use in Home Theater In a Home Theater application, the placement of Left and Right Front Loudspeakers can be limited by such considerations as the size and location of the video monitor. The locating suggestions in the for use in a Music System section below can still be helpful as a starting place. Refer to figure 10. Locating Loudspeakers for use in a Music System When used in a Music System the distance between the Loudspeakers and the listener to the Loudspeakers should form a equilateral to an acute isosceles triangle. If the speakers are too far apart relative to the listener, some imaging can be lost. Refer to figure 11. Figure 9 Figure 10 Figure 11
