Instruction Manual

Mounting the IWTS-28 SUB

NoTE: We always recommend a professional be involved in the

installation of IWTS speakers, if at all possible.

You will need the Grille/Frame assembly GFR-626, sold separately.

ensure that the clamps have adequate room to rotate. A stud or other

obstruction that's too close will stop them from properly doing their job.

Installation of the IWTS-28 SUB in New

Construction

Atlantic Technology offers an optional Rough-in Frame Kit to ease instal-

lation in new construction. Instructions for its use are included with this

kit. Ask your Atlantic dealer for more details. The kit's model number is

IN-NC-626.

Installation of the IWTS-28 SUB in Existing

Construction

Removing and Installing the Grille

Remove the grille from the speaker using an awl or the point of a drywall

screw in a grille opening near one of the grille corners. Slowly pry the grille

out, being careful not to damage the speaker's frame or its finish.

To re-install the grille later, press it carefully into the appropriate opening in

the frame assembly. Since it's designed to fit snugly, please take your time

and use care when installing the grille.

The GFR-626 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. Here are some

important precautions to take

before mounting:

Keep the sides of the actual

mounting hole at least 1½ inches

away from beams or studs to

Treating the Wall Cavity

The IWTS-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 items that could rattle or vibrate from the 28

SUB's output. A subwoofer moves a considerable amount of air, and if

something can rattle, it probably will rattle. It's much, much easier to

'button everything 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

28 SUB.

• Fill the wall cavity loosely with acoustic speaker stuffing ("polyfill"). It

is not necessary to pack the stuffing in extremely tight; in fact, that will

reduce the bass output.

• If this is new construction, we strongly recommend using

sheetrock. It's heavier and more expensive than ½" material, but it's far,

far superior in terms of acoustic/mechanical integrity and rigidity. We

also strongly recommend that the sheetrock be screwed to the studs

every 6 inches or so, instead of the more common practice of nailing

it every 12-18". Use screws for at least a full stud bay on either side of

where the 28 SUB will be mounted.

• If you drill a hole in the stud to snake the speaker wires through, be

certain to seal that hole with silicone caulk.
