marked on the appliance.
11. Grounding or Polarization - Precaution should be taken so that the
grounding or polarization means of an appliance is not defeated.
12. Power Cord Protection - Power supply cords should be routed so
that they are not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at plugs,
receptacles, and the point where they exit from the appliance.
13. Cleaning - The appliance should be cleaned only as recommended by
the manufacturer.
14. Non-use Periods - The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.
To remove all power (supply mains) from the appliance, remove the
plug from the wall outlet.
15. Object and Liquid Entry - Care should be taken so that objects do
not fall and liquids are not spilled into the enclosure through the
openings.
16. Damage Requiring Service - The appliance should be serviced by
qualifi ed service personnel when:
A. The power supply cord or the plug has been damaged; or
B. Objects have fallen, liquid has been spilled into the appliance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally; or
E. The appliance has been dropped or the enclosure is damaged.
17. Servicing - The user should not attempt to service the appliance
beyond that described in the operating instructions. All other servicing should be referred to qualifi ed service personnel.

INTRODUCTION
Product Description
The Complement® SUB105 is a compact, high-powered
active subwoofer with a comprehensive feature set for
installer and user convenience. Its powerful amplifi er
couples with an acoustically optimized cabinet and
driver to provide high performance with a deep low end
and smooth response.
Features
For installation fl exibility, the SUB105 offers stereo linelevel inputs, a line-level LFE input, a balanced line-level
stereo input via CAT-5 cable, and stereo speaker-level
inputs with pass-through.
An adjustable level control, a variable crossover, and a
phase switch allow the user to precisely balance the sub
with the other speakers in the audio system. Frontmounted controls make it convenient for the user to
make adjustments and turn the subwoofer on and off.
An automatic standby mode turns the subwoofer on
as soon as it senses an audio signal and mutes it 20
minutes after the signal ends. A front-panel power
indicator glows amber for standby mode and green for
fully on.
The subwoofer’s attractive compact design provides
versatile placement options without compromising the
home décor.
Because the subwoofer’s location affects how standing waves are created, correct subwoofer placement is
important to avoid such peaks and nulls. They can’t be
fi xed by equalization, which could overdrive the speaker
and amplifi er, causing distortion or damage.
The fi rst step toward getting accurate bass response is
to set the subwoofer’s crossover to match the low-frequency roll-off point of the main speakers. Once you’ve
set the crossover, you can then experiment to fi nd the
best possible location for the subwoofer.
Corner placement
Placing the subwoofer in a corner will result in maximum volume, greatest effi ciency, and lowest distortion.
This is because the adjacent walls and fl oor reinforce
the fundamental bass tones. However, corner placement
can also make the subwoofer sound boomy, emphasizing a single frequency above others and resulting in
uneven frequency response.
Other placement options
To get a smoother, more even frequency response, place
the subwoofer at varying distances from the walls of
the room. The key to minimizing standing waves is to
avoid symmetry. Also, place the subwoofer close to the
main speakers. This will help blend and integrate the
sound of the sub and the main speakers. At the very
least, keep the subwoofer in the front half of the room.
Applications
The SUB105 is ideal for use in home theater and stereo
music systems. The perfect match for Russound Complement LCR7 on-wall speakers, it can also be used with
any Russound in-wall or in-ceiling speakers.
The balanced line-level RNET A/V input makes the
SUB105 especially useful when the audio source is
remotely located, such as in an equipment cabinet. By
using CAT-5 cable, the installer can avoid transmitting unbalanced signals over long distances, which can
degrade the signal and introduce noise.
Subwoofer Placement
Room acoustics and modes
Room acoustics have a great effect on the sound of
speakers, especially subwoofers. When sound is refl ected
back and forth between two parallel surfaces, such as
opposite walls in a rectangular room, it creates standing
waves. These make bass response uneven by creating
sound peaks and nulls at certain locations within the
room.
A common technique for fi nding the best location is
to put the subwoofer in the main listening position, at
seated ear height on a sturdy, nonresonant platform.
Play music with ascending and descending bass notes,
such as a jazz recording with a walking bass line. Crawl
around the fl oor until you fi nd the spot where the bass
sounds smoothest, and where each bass note has about
the same volume and clarity. Avoid positions where
some notes resonate longer or sound heavier than others. When you’ve found the place where the bass sounds
best, put the subwoofer there.
Multiple subwoofers
Using multiple subwoofers provides greater dynamic
range and smoother bass response throughout the room
than using only one subwoofer. Placing two subwoofers in the corners behind the main speakers will reduce
room resonances and increase directly radiated sound.
When placing two subwoofers in adjacent corners,
position them asymmetrically to minimize the effects of
standing waves.
