Speaker Installation HORIZONTAL PLACEMENT RECOMMENDATION Traditionally, proper horizontal placement of speaker systems slightly behind (not on) a meter bridge accomplished two purposes: it allowed both woofer and tweeter to be at ear level, and many times, it permitted the recording engineer to see over the speakers and into the studio. Horizontal placement is a recommended arrangement with the M1 Active Mk2 because the left and right mirror-imaged pair permits a symmetrical alignment of drivers and ports. This will be conducive to a balanced mix. See Figure 2 below. Proper tweeter orientation is toward the stereo image center (the middle) as shown. Ports are always faced toward the bottom side of the cabinet. This setup will promote a strongly focused center image such as for the vocalist. And because the (vocal) image width will be narrower than if the speakers are placed vertically, it will be possible to place the vocalist with great precision at stage center. In this orientation there will be much less chance of first reflections from either sidewalls or the console coloring your mix. M1 Active Mk2 Reference Manual 21
