Threaded Insert Multi-Position Adapter Upper Half of Speaker Bracket -- Mad Figure 1 Wall Mounting Options for M50 that come with the stands. Be sure to use the plastic washer (supplied with the stands) between the stand bracket and the back of the speaker as shown. [. . . ] You can also invert and replace the grille panel to restore the logo to a right side up position. Should you wish to orient M80s horizontally, we recommend repositioning the tweeter/mid-range mounting plate as shown in the diagram Horizontal Position below. Mounting Plate Vertical Positions Woofer Tweeter Midrange Mounting Plate Rotation Procedure 1. Place the speaker on its back panel, so the front panel faces up. Remove the four hex-head mounting screws from the mounting plate using the supplied allen wrench. Carefully lift the mounting plate assembly about an inch off the cabinet. Rotate the plate 90 degrees and realign the plate's screwholes with cabinet's pilot holes. Replace the mounting screws, being careful not to over-tighten them. The grille panel's logo plate can be repositioned, if desired. Replace the grille.

Use 16 gauge or heavier speaker cable for longer runs. Determine how long the speaker cable should be for each speaker. Cut the speaker cable into the appropriate lengths. Strip 1/2" of insulation from the two individual conductors in the speaker cable. [. . . ] There is little advantage in using more power than 100 watts per speaker, but a receiver above this power rating can be used so long as the receiver is not operated at distorted levels. Warning About Excessive Amplifier Distortion Operating a receiver (of any power rating) beyond its maximum undistorted output level creates distortion ­ added high frequency sound not part of the musical program. Distortion dramatically increases the internal operating temperature of a speaker and will eventually cause the speaker's failure due to burned or melted internal parts. While Cambridge SoundWorks includes the most heat-tolerant parts commensurate with good acoustic design, the speaker's Limited Warranty against defects in materials or workmanship does not apply to parts that fail from long-term operation at very high temperatures. M60: Dimensions: 13 1/4" H x 8 1/4" W x 9 1/4" D Weight: 14 pounds each Impedance: nominal 8 ohms The M60 can be safely used with any receiver rated above 20 watts per channel. [. . . ]
