Another set of variables is the shape and volume of your
listening room. Large rooms require more bass energy to excite
waves within them. Small rooms need less energy, but reflect it
differently. And then there’s the fact that most rooms don’t have
four walls anymore, but open into dining rooms, lofts, cathedral
ceilings, etc. All of this means that predicting sound interaction
patterns is very difficult due to the irregularities of the room
shape.
As you can see, room acoustics is an important but compli-
cated subject (To learn more about room acoustics, send for
AudioControl’s Technical Paper 107, “Small Room Acoustics De-
Mythologized”). The overall point that we’re trying to make is
that the various rooms in your home function as gigantic mechani-
cal equalizers, boosting or cutting certain frequencies depending
on size, shape, volume, acoustic treatment and the position of the
speakers.

It may take several series of adjustments since there is some
interaction between each control. We have included some sample
settings and general descriptions of each control’s function on
page 13.
After initial adjustment the only time you would change the
control settings are 1) if you connect different speakers into the
system, 2) if (assuming the speakers aren’t built-in) you move
them significantly, such as from a bookshelf to floor stands, or 3)
if your room acoustics change through rearrangement of furniture,
wall or floor coverings, large hairy dogs, etc.
The following are examples of typical settings along with short
descriptions of each Architect Model 700 Speaker Optimizer
control. Naturally, the results of adjustments will vary depending
on the acoustic environment, type of speaker and sound sources
you are using, but this is a good starting point.
For an extensive description on the use for the SA-3052 real
time spectrum analyzer for these settings, please see that product’s
manual.
