6) Tighten (drive clockwise) the screws that turn the mounting clamp dog and tighten them.
Try to tighten each clamp the same amount, being careful not to over tighten them. See
diagram below for details.
Turn the mounting
clamps against the
enclosure, then
place the speaker
in the mounting
hole. Use a phillips
head screwdriver
to deploy the
mounting clamps
and pull them
against the back
of the drywall.
7) Replace the speaker grille.
Note: The IW-SR30 is sold in pairs. On the cabinet, near the input terminals, is a temporary label
to specify screen direction. The response will be slightly superior in this direction. Install the
two IW-SR30’s so that the arrows BOTH point toward the screen. If listeners are not going to be
located on or near the center axis of the speaker, the speaker should be oriented with the arrow
toward the listener location (even if this is away from the screen).
SETTING THE IW-B7 AND IW-C7 CONTROL SWITCHES
The IW-B7 and IW-C7 have three switches that let you adjust its sound to suit your listening
environment.
Bass Loading
– When a speaker is placed close to a corner (or any boundary that forms a
corner such as a fi replace or a large column), the bass output is emphasized. Setting the Bass
Loading switch to the Boundary position slightly reduces bass output, thus preventing the
“heavy” sound quality that can result from a speaker being placed close to a corner. When the
IW-C7 is positioned at least 18” from the corner the Normal switch postion will usually produce
the best sound balance.
Treble Level
– This 3-position switch controls the “brightness” of the sound. Set the switch to
“+1dB” to increase the high-frequency output in situations where the speaker sounds “dull”.
This can occur when the listening room has a lot of heavy carpeting, drapes, etc. that absorbs
high frequency sound. Set the switch to “–2dB“ when the sound is too bright, which can hap-
pen in rooms with more hard, refl ective surfaces. For typical rooms, with a balanced mix of hard
and soft surfaces, set the switch to “0dB”.
