Location Considerations
Choosing the location for the subwoofer is a very important consideration.
Since the IW-28 SUB can't easily be moved once it's installed (!), very care-
ful consideration should be given to its placement. In general, the cleanest
and most articulate delivery of bass energy into the room occurs when the
subwoofer is placed asymmetrically with respect to the room's dimensions
and is located along the same wall as the left and right speakers. If this is
not possible, try to locate it within the front half of the room. (see fig. 1).
Such placement generally results in the best overall balance of bass impact
vs. 'one-note boom. '

FRONT
If you are using two IW-28 SUB modules, follow the same advice: locate
them asymmetrically within the room and asymmetrically with regard
to each other (i.e. one near a corner, one towards the middle of a wall) to
smooth out the bass and minimize random standing wave patterns. (see
fig. 2)

Connection Considerations
Choosing how you connect the IW-28 SUB is dependent upon your appli-
cation. In a Home Theater it should be powered by an external monoblock
amplifier, such as Atlantic Technology's SA-180 with its EQ circuit that was
specifically designed to get the very best performance out of the IW-28 SUB.
In a traditional 2 Channel System it may be used as a passive subwoofer
if your receiver does not have "sub out" and/or an additional monoblock
amplifier is not desired. In a Distributed Audio system it can be used either
way depending upon your system. We will cover each of these applications
separately.
