The MG1.6'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 MG1.6, the
tweeters should be placed on the outside.
