User manual MAGNEPAN MG12-QR

[. . . ] ASSEMBLY The four support feet for the MG12 are shipped in the speaker carton along with the 8 mounting bolts. Install the foot supports on the back of the speakers and tighten the bolts. HOOKUP The MG12 features unique, high current connectors which provide optimum contact area with speaker cables up to 10 gauge. Simply strip 1/2" of insulation from the end of the cable. [. . . ] Begin moving the speakers forward or backward in increments of 6 to 12 inches. One position in the room should be noticeably better than others. Also experiment with your chair location. Positions close to a wall will often result in increased bass (often too much). B) STEREO WIDTH AND IMAGING--Once you have located the best position for the speakers and your chair for bass performance, separate the speakers by 50% of the distance from your chair to the speakers. (For example, if your chair is 10 feet from the speakers, move the speakers 5 feet apart. ) Now, move the speakers apart in increments of 3 or 4 inches at a time, listening carefully at each position. At some point you will start to hear two separate speakers instead of a "stage effect" (or continuous image). When this occurs, your speakers are too far apart: begin moving the speakers back in small increments until you notice a point at which you achieve one cohesive "sound stage. " For best results listen to speakers on axis with the listening position as shown in Figure 1 and 2. Figure 1 Figure 2 C) LEFT/RIGHT--The MG12's are matched pairs and mirror-imaged. The serial number for each speaker in the pair is the same, except for a "1" or "2" following each serial number. As you face the front of the speakers, the speaker with the "1" after its serial number has the tweeter near the left edge, and the speaker with the "2" has the tweeter near the right edge. To obtain correct phasing between the tweeter and bass of the MG12, the tweeters should be placed on the outside. NOTE: Once you have located the ideal speaker position you should mark it. A small tack or piece of tape can be placed on the carpet so that your ideal listening spot can be easily relocated when the speakers (or chair) are moved for cleaning, etc. In the event that your ideal listening spot is inconvenient from the standpoint of the room layout and decor, simply slide the speakers wherever they look best. Experience has shown that the speakers can be placed close to a wall, and it will make little difference for FM or background listening. The entire placement procedure may seem like a great deal of work, but is necessary in the setup of any high quality system. The time and effort expended should be necessary only once, and will repay the owner with countless hours of musical enjoyment. ROOM ACOUSTICS Magneplanars, like other bipolar speakers, usually sound best with a moderately reflective surface behind the speakers. In situations where the speakers must be placed as close as 2 feet from the back wall, a heavy damping material directly behind the speakers is advised; however, it should not cover the entire wall. Damping material in other parts of the room is a matter of trial and error. [. . . ] Other values are available from your Magneplanar dealer. Figure 3 10. MAINTENANCE A. The hardwood frames can be cleaned with a slightly damp dust cloth. Light vacuuming of the grille cloth is possible. 11.
