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.
Speaker placement
Avoid reflections
While near-field monitors are fairly 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 within a
larger room placement 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.

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 the
port. Do not place the Monitor Ones inside a bookshelf or other closed
chamber, such as a wall soffit. The Monitor Ones are designed to be used
in free space. Otherwise, bass frequency response will be adversely
affected.
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
console to deal with. Unfortunately, the console itself can be a major source
