Instruction Manual
Front Panel Controls
The IWTS speakers have three
controls that help optimize
the speaker’s performance
regardless of mounting loca-
tion or room acoustics.
HF (High Frequency) Level Control
This control adjusts the relative level of high frequency
output to compensate for varying room acoustics or
placement behind a screen.
“+” is for absorptive, acoustically “dead” rooms (or when
the speaker is behind a movie screen). Use this position
to increase the HF level and restore the proper sparkle and liveliness to
the sound.
“0” is for rooms of average absorptive characteristics.
“-“ should be used in rooms that are highly reflective, with hard floors
and exposed windows.
The setting of the HF control is mostly a matter of personal taste, so try it
in all three positions and see which one is preferred.
Boundary Compensation Control
Large room boundaries, such as floors, walls, and ceil-
ings, reinforce sound by acting essentially as acoustic
“mirrors.” When the speaker is mounted too close to the
corner or a wall/ceiling intersection, this sonic “reinforce-
ment” often results in an unnatural heaviness or color-
ation of the sound.
If it’s necessary to mount the speaker closer than 12 inches to the ceiling or
corner, you may find that by switching the Boundary Compensation control
“on,” the speaker sounds better. We recommend that you try the control in
both positions and see if it helps in your particular installation.
Directional Vector Control™
Oftentimes, it is visually advantageous to mount the
speaker high up on the wall, as this puts the speaker
above the field of vision and thus prevents any intrusion
by the speaker into the room’s décor.
However, acoustically, the best location for a speaker is at
seated ear level, about 3-4 feet off the floor.
The DVC electronically directs the midrange sound at the listener’s ears,
even when the speaker is mounted high up on the wall.
The “on” position directs the sound down at the listeners when using the
speakers as LCR theater speakers or primary stereo music speakers.
The “off” position fires the sound straight out from the speakers—above
the listener’s heads—which is perfect for non-localizable surround use, or
for room-filling background music (“whole house audio”) use.
IR Knockout
There’s an IR “knockout” plug in the upper right corner
of the front baffle. If you are using a multi-room con-
trol system, you can install a standard IR receiver in the
knockout hole.
