Installation
CABLES - RCA UNBALANCED
When installing your new subwoofer using unbalanced RCA connections, you should use
high quality shielded coaxial cables. Poor quality cables may pickup interference and result
in hum or noise. Keep the length of cable as short as possible and route all input signal
cables away from power cables to reduce the potential of induced noise.
CABLES - XLR
When using balanced XLR connections, be certain to use a high quality cable that maintains
proper connections to each pin, the pins are often marked with numbers. If an XLR cable
that is improperly wired is used, subwoofer performance may be degraded and you may
experience increased noise and/or hum. Due to various design differences between different
brands & types of equipment (e.g. different ground methods for power supplies and signal
reference) and long cables required in some installations, there is a potential for any product
to pickup noise via the connections and/or connected equipment (via ground loops).
SPEAKER LEVEL INPUT AND OUTPUT
The Speaker Level inputs allow you to connect your subwoofer via the speaker outputs of
any A/V receiver, stereo amplifier/receiver or power amplifier. This signal is sent through
a high pass filter within the Subwoofer en route to the Speaker Level output terminals.
You may then wish to connect your main/satellite speakers via these output terminals
rather than directly from the amplifier/receiver, thus reducing the bass load on your main
speakers and improving overall performance.
PLACEMENT
While true subwoofers operate at extremely low frequencies which are primarily omni-
directional, keep in mind that frequency response and output level can be dramatically
influenced by where you place the subwoofer within the room. Placing the subwoofer in
the wrong location may degrade sound quality, limit low frequency response and reduce
maximum output level, substantially reducing your overall listening pleasure. Many rooms
often end up with non-optimal placement, depending on the size and location of the
furnishings within your room and if the possibility to reposition them exists. Finding the
optimal location usually requires some experimentation to determine what sounds best in
your room, from your listening position. We suggest you read the general guidelines below
and setup the subwoofer in one of the suggested locations.
Proceed to listen to the loudspeakers multiple times, trying a few different locations before
settling on the final location. To do this, perform basic setup and listen to a familiar music
track or movie scene. Then move the loudspeakers to an alternate location & repeat listening
to the same music track or movie scene. If you have a test CD and SPL meter, performing
a basic frequency response test can help you determine which location provides the best
frequency response.
GENERAL GUIDELINES
In most rooms, the optimum location for your subwoofer is in the closest solid front corner
(figure 1) This provides the most bass output, but may be boomy. You may move the
subwoofer to a moderate location such as behind the main speakers (figure 2) or for even
less impact but most controlled perfomance by placing it between the two main speakers
(figure 3) away from the walls.
When using a pair of subwoofers in stereo, it is preferable to place each subwoofer by the
satellite of the same channel, (see figure 4). If you want a more flat frequency response and
the bass evenly distributed over a larger area of listening positions, then four subwoofers
one in each corner is a terrific option.
The figure
5
below shows alternative subwoofer placement options with subwoofer/-
placed at the midpoint of the wall. This can be used for one subwoofer with the subwoofer
placed in the front, for two subwoofers with the subwoofer placed at the front and back and
for four subwoofers with the subwoofers placed in the mid point of each wall.
