H ORIZONTAL P LACEMENT R ECOMMENDATION
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 set-
up 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.
