Mounting the IWTS Speakers
NOTE: We always recommend a professional be involved in the
installation of IWTS speakers.
The IWTS speaker can be easily mounted in most any standard wall mate-
rial, 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 ½ inch away from
beams or studs to 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.
Wall cavity size will affect the bass and midrange performance of any
in-wall speaker. The IWTS-5 LCR is designed to play optimally in a 0.5
to 1.0 cubic foot space (measured before wall insulation is inserted) and
the IWTS-10 LCR in a 0.75 to 1.5 cubic foot space. Cubic dimensions can
be determined by multiplying the length x width x height of the cavity. A
larger cavity won't hurt, but a smaller one will negatively impact the bass
and midrange response of the system.
Some of the sound from the speaker will transmit to the space on the other
side of the wall cavity. If this is a major concern, you can build a box within
the wall that provides the required cubic volume. Please note that there is
very little room behind the drivers in a standard "2 x 4" wall cavity (there's
only 1/4 inch), so the back of any enclosure box must be made from thin
material. Typically then, the back wall material of your enclosure will be
roughly 1/8 to 1/4 inch thick.
For optimum sound install we recommend lining the cavity with fiberglass
or polyfill, observing all the relevant precautions and instructions from the
insulation manufacturer. If you have built a back box, you can use common
fiberglass insulation or open cell foam rubber in the enclosure. Be sure to
push the insulation back from the drivers to ensure that it doesn't get into
the moving cone area.
IWTS-10 LCR In-Wall Enclosure Recommendations
Please use this information to construct an in-wall enclosure if you so
desire. Doing so will generally improve the performance and increase the
power handling of the system.
Be sure to line the cavity with insulation, being careful to avoid letting the
insulation touch the backs of the woofer cones. It's also important to seal the
joints of the enclosure with a high quality non-shrinking caulk.
Be careful to keep the wires from touching the chassis of the drivers or baffle
in such a manner that the wire might vibrate and buzz. You may use nylon
wire ties to keep the wires properly positioned. Such ties are available that
are designed to screw directly to studs making them ideal for this purpose.
As always, take care to wire the speakers properly, with the positive lead
(normally marked with a red terminal or a "+" sign) from the ampli-
fier connected to the positive terminal on the speakers and the negative
(marked with a black terminal or a "-" sign) connected to its respective
terminals.

Ceiling Mounting
It is especially important when mounting the speaker in a ceiling that you
cover the back of the system with a fiberglass window screening (available
at any home center or hardware store) to keep insulation and other foreign
matter out of the assembly. You also should install safety wires from the rear
of the assembly to a secure mounting place, like adjacent beams or the floor
above, for added security. Should you be installing IWTS speakers in a sus-
pended ceiling, it is imperative to install safety wires from the speaker to the
support structure above, to ensure security under all conditions.
