Fact: Subwoofers reproduce frequencies with
wavelengths that are long in relation to the dimensions
of most living rooms. Standing waves will boost or
cancel various frequencies due to the interaction with
the room boundaries. Moving a subwoofer in a room will
change what you hear in the listening position a lot.
For maximum bass reinforcement, the MiniMe
subwoofer system should be placed in the corner of your
living room, with the subwoofers facing the wall. This
creates acoustical coupling with the walls, which in turn
leads to a 9 decibels of boost in the overall response of
the MiniMe. Keep a 3" clearance between the
subwoofer and the walls.
Fine tuning the MiniMe requires adjustments to
the crossover point, volume control and the phase
switch. These controls are located on the side of the
enclosure. For ease of tuning we recommend that you
turn the MiniMe around to expose the controls, and
place it in position (corner). Set your stereo system to a
moderate listening level and adjust the MiniMe
accordingly. The MiniMe is equipped with a 24 dB / Oct.
Low pass filter designed to eliminate vocals from
entering the system. When tweaking, gradually reduce
the crossover point setting to eliminate vocals from
seeping into the amplifier.
Your Earthquake MiniMe is designed to be placed in a
corner and this will produce optimum performance.
Experiment with at least two corners then decide which
is the best.

#1 is very good positioning.
#2 is also excellent but may shake the back wall too
much and cause things on or along the walls to rattle too
much. If this occurs, use the #3 position.
#3 Move the woofer approximately three feet away from
the right wall and place it along the back wall as shown.
This will substantially reduce the rattling of the back wall
and will still pressurize the room with lots of bass.
Although low frequencies are non directional, factors
such as room reflections, standing waves, resonance,
and absorption strongly affect your subwoofer's
performance.
Also position the control panel so that it is not touching
anything and can receive good ventilation.
Using Two Subwoofers
If you choose the use two woofers, the sound output will
double (an increase of ~5dB). Locate the woofers with
one in each corner and experiment with the location and
phase control to achieve the best bass response.
Always drive each woofer through the Left/Mon input
even though you are driving one woofer on a right
channel drive and the other with a left channel drive. If
your pre-amplifier has a single dub/LFE output, use a 'Y'
cable to split it into two outputs.
Remember to keep it at least two or
three feet away from any TV screen,
computer, VCR or magnetic tapes and
discs. This will reduce the chance of
the magnetic field upsetting the TV
screen or erasing your magnetic media.
