Unpacking and Inspection
The Red Mountain Subwoofers are packaged extremely well to make sure no damage
occurs during shipping. Carefully open the box and remove the speaker. Inspect it
immediately for any kind of damage. The speaker should have left our warehouse in
perfect condition so any damage that has occurred probably happened in transit from
our warehouse to your address. If for some reason damage has occurred, please
contact your Dealer or TruAudio immediately. We recommend that you retain the
packaging in case a need arises for you to transport your loudspeakers.
The RM-12Sub and RM-10Sub besides the actual subwoofer cabinet and grill, should
also come with: this instruction manual, a warranty card, and a power cord. Four,
heavy-duty plastic feet come attached to the bottom of the cabinet.
Caution; for NO reason should you open this subwoofer.
This will void the warranty!
To reduce the risk of electrical shock and fire, do not remove the amplifier panel from the back
of the cabinet or do not remove the subwoofer from the front of the cabinet. There are NO
fuses or serviceable parts.
All service to this product MUST be done by a TruAudio Authorized repair center.
Before installing the subwoofer, please read the following instructions:
Always turn off the power of your receiver/preamp and the powered subwoofer.
When turning your amplifier/receiver back on, make sure your volume is turned all
the way down.
Never expose this subwoofer to excessive cold, heat, humidity or direct sunlight.
This device should never be used in, on or near water due to risk of fatal shock.
DO NOT attempt to open or dismantle this subwoofer.
These models should always have plenty of Air flow to reduce the chance of over
heating.
Subwoofer Placement
This subwoofer is engineered, designed and built to reproduce low frequencies at and below
150Hz. Frequencies at this level are basically omni-directional. This makes it easy to find a
good place for the sub; however, there are also several location options that can either give
more or less bass. When placed near a wall, you will get louder, deeper bass. Placing the
subwoofer in a corner will produce a high volume of bass output, while near only one wall will
provide less bass. Placement away from any wall may not produce enough bass. Because even
a slight change of how the unit sits will alter the bass output, we suggest trying your subwoofer
in different locations. This will allows you to hear the difference of bass output and decide
what is best for that particular room and the listener’s preference.
Our suggestion is to place the subwoofer close to the pair of speakers it will be matched with.
For example, if the subwoofer is to reproduce bass from the front two channels, then it should
be located near the front two speakers. If it’s to reproduce bass from the rear effect channels,
then the sub should be located near the rear speakers.
Because the Red mountain series of subwoofers are ported from the front, they can be built-in
to a wall, into cabinetry etc………NOTE; even though they are ported from the front, the amp
panel is still located on the back of the subwoofer cabinet. They need to have proper ventilation
for the amp to “breath”. If the subwoofer will be “built-in”, make sure there is enough space in
