Model IW-28 SUB

In-Wall Thin Bezel Subwoofer

Thank you for purchasing Atlantic Technology products. Our speaker sys-

tems have been designed to deliver exceptional sound and value. We hope

you like what you hear, and are happy with your decision to buy them.

Please take a few moments to read these instructions. They’re intended not

only to tell you how to mount the speaker, but how to get the best perfor-

mance from it.

Unpacking the Speaker

Use care when unpacking the speaker. Remember to save all packing

materials until you are certain that the speaker has suffered no damage in

shipment. If you ﬁnd such damage, either visible or internal, contact your

dealer immediately.

If you can do so, save the carton, packing pieces, and plastic bags that came

with your speakers. They will be useful in case you move or have to ship

your loudspeaker for any reason.

Description

The IW-28 SUB is a thin bezel, in-wall, passive subwoofer that has dual

8” long throw woofers, a ¾” reinforced MDF bafﬂe and a switchable Low-

Pass crossover that will provide you years of enjoyment. The IW-28 SUB is

designed to be used with either a monoblock ampliﬁer, such as our SA-180

in a home theater application or as a passive subwoofer connected in par-

allel with the L/R speaker in a traditional 2 channel audio system. It may

also be used in a distributed audio system to add dynamic range that most

people are missing in today’s whole house installations.

Speaker Placement

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.
