CHAPTER 2: INSTALLATION
Like any speaker system, your Monitor Ones will work best
when properly positioned in a suitable acoustic environment.
Achieving proper speaker placement is usually straightforward,
but even with near-field monitors, speaker placement and the
acoustics of the listening room itself are too often overlooked and
can become significant contributors to an inaccurate and
uninspiring monitoring environment.
Please take a moment to read this information carefully. It will
help you to get the most use and enjoyment from your new Alesis
monitors.

2.0 SPEAKER PLACEMENT

While near-field monitors are more forgiving of the
surrounding room acoustics, it is always prudent to optimize the
listening environment whenever possible. First, the user should
be aware of the effect that the size of the listening room can have
on low frequency response. In general, the smaller the room, the
stronger the bottom end will be, although placement within a
larger room can also make a difference. This has to do with the
way low-frequency waves travel in closed spaces. If you find your
monitor system to be either light or heavy on the bottom, try
moving them around within your listening room. Also, because the
Monitor One's SuperPort tube is located at the rear, position the
monitors at least six inches away from anything that would block it.
You should avoid locating your Monitor Ones near reflective
surfaces such as glass, tile, large open walls or table tops. Still,
many rooms used for recording have these surfaces, so the best
way to deal with them is to place the monitors out in the room
away from reflective walls, windows and sizable objects.
Even with these reflective surfaces separated from the
monitoring position, typical mixing situations usually still have the
top surface of the mixing board to deal with. Unfortunately, the
board itself can be a major source of reflections and the additional
acoustic conduction into the board can affect your monitor's
amplitude and phase response. Speaker placement on the
console's meter bridge provides for two clear acoustic paths
between the speakers and the recording engineer which results in
undesirable comb filtering effects and poor imaging. The first path is
the direct one, and the second is via a reflection off the mixer main
