Instruction Manual
Distributed Audio Connection
How to install the IW-28 SUB with a distributed audio system is dependent
upon your specific system. If your source has "sub out connection" follow
the "monoblock amplifier connection" instructions. You may use a chan-
nel from your amplifier to power the subwoofer or Atlantic Technology's
SA-180 monoblock amplifier.
IMPORTANT! Set the IW-28 SUB's front-panel Low-Pass switch to
the "off" position. This will bypass its crossover.
Alternately, remove the jumpers from the IW-28 SUB's terminals (see fig.
4). Run speaker wires from the amplifier's left speaker terminals to one set
of terminals on the IW28 SUB. Run another set from the amplifier's right
speaker terminals to the other set of terminals on the IW-28 SUB. (see fig.
5) It does not matter which set of terminal on the IW-28 SUB is considered
'right' or 'left'. Be careful to observe consistent polarity. All reds and blacks
should be consistent.
IMPORTANT! Set the IW-28 SUB's front-panel Low-Pass switch to
the "on" position. This will filter out any signals above 200 Hz from
reaching the IW-28 SUB module.
IMPORTANT NOTE: Each individual woofer in the IW-28 SUB is 8
ohms. Consult your amplifier's instruction manual for more informa-
tion on its impedance drive capability.
Mounting the IW-28 SUB
IMPORTANT! Keep the sides of the mounting hole at least 1½ inches
away from beams or studs to ensure that the clamps have adequate
room to rotate into position. A stud or other obstruction that's too
close will stop them from properly doing their job.
NOTE: We recommend a
professional be involved in
the installation of In-wall
speakers, if at all possible.
The IW-28 SUB woofer module
can be easily mounted in most
any standard wall material, from
½ to 1½ inches thick. Its rotating
wall clamps (sometimes called
"dog legs") firmly fix it to the wall
surface after the proper cutout
has been made.
Installation of the IW-28 SUB
Removing and Installing the Grille
Remove the grille from the speaker using the enclosed tool, an awl or the
point of a drywall screw in a grille opening near one of the grille corners.
Slowly pry the grille away from the frame, being careful not to damage the
speaker's frame or its finish.
To re-install the grille later, press it carefully into position, over the frame
assembly. The grille is secured by magnets in the frame and fits snugly.
Please take your time and use care when installing the grille.
Treating the Wall Cavity
The IW-28 SUB does not require a back-box. It is designed to work prop-
erly in a standard full-sized wall cavity. This is commonly called an "infinite
baffle" installation. However even though there is no back-box, you should
exercise good acoustic/mechanical common sense, and prepare the wall
cavity as follows:
• Make sure there are no extraneous house electrical wires, plumbing,
junction boxes, or other loose items that could rattle or vibrate from the
IW-28 SUB's output. Seal all the holes in the cavity with flexible caulk-
ing. A subwoofer moves a considerable amount of air, and if something
can rattle, it probably will rattle. It's much, much easier to 'button every-
thing down' securely before you install the sub then it is to try to hunt
down an intrusive buzz or rattle later on.
• Seal all the stud-to-drywall seams with a flexible silicone construction
caulk. This will help keep the drywall itself from flexing and rattling
against the studs, and it helps form a more airtight "enclosure" for the
IW-28 SUB.
• Fill the wall cavity loosely with acoustic speaker stuffing ("polyfill" or
unfaced fiberglass insulation). Do not pack the stuffing in the cavity
tightly, as that will reduce the bass output.
