For acoustic purposes Alesis has closely grouped the Monitor Two’s three
drivers together which necessitates mounting the high frequency dome driver on
one side of the mid/low frequency drivers. Therefore, your Monitor Twos are
supplied as a pair of mirror imaged cabinets, called the A and B side. Either
speaker cabinet can be oriented horizontally or vertically as long as a few simple
rules are followed For most near to mid-field monitoring applications the
mounting orientations shown in Figures 4a and 4b below are recommended.
Figure 4
Recommended left-right speaker orientation and mounting elevation
Speaker mounting elevation is important so our “ear level”
recommendations are shown in Figure 4. If the speakers are
mounted vertically as shown in Figure 4a, position the speakers so
that your ears are level with the high frequency dome driver. This
puts the low frequency driver slightly below ear level and the
midrange driver slightly above. If you are mounting your speakers
horizontally as in Figure 4b, the ear line should be centered on the
low and mid frequency drivers. Finally, if you are unable to mount
your monitors at ear level, rotate the cabinets forward or back so
that the points marked “ear-level” are perpendicular to your ears.
The Monitor Two system will produce the smoothest frequency
response when both speakers are perpendicular . In this three sided
triangle, the listener is said to be in the speakers’ “sweet spot”. In
reality, however, the listener needs to move around a bit and
therefore its helpful to know how the speaker’s sound field will
change with other listening positions. Therefore, our last word
