Care

To maintain the speaker cabinet's finish, first
unplug the power cord and then use a soft, slightly
dampened cloth to clean the surfaces and finish off
with a dry cloth.

To keep the large rubber surrounds soft and
supple for 20-years or more, treat them with mink oil,
available ta most shoe repair stores. Rub a generous
amount into the surrounds with a soft cloth about once
a year (more often if you line in a dry climate).

Installation

Observe the following general precautions and
read the safety instructions before powering your
Earthquake subwoofer.

• Never open the cabinet or remove the metal control
panel as this might result in an electrical shock to you,
or damage to the unit.

• Protect it from prolonged exposure to direct sunlight
and other direct sources of heat, such as heating
vents and radiators.

• Do not let anything come into contact with the panel
and keep at least two inches away from any walls.

The metal control plate serves as the amplifier heat
sink and also as a conduit to remove internal heat to
the outside and into the atmosphere. It can reach
temperatures of 60° C, which will feel hot to the touch,
using nerves of flesh and blood as temperature
sensors. As uncomfortable as it may feel, 60 degrees
C cannot burn you, and in fact is almost cool to

Connections

Please consider the following when setting up
your new system:

• Before making or changing any connections,
ALWAYS make sure that the subwoofer is unplugged
from the wall and your other components are turned
OFF. Also, turn down the volume control of the
subwoofer and your pre-amplifier or receiver.

• This diagram shows all the low power components
sharing a power strip which is connected to the same
outlet used by the amplifier.

• The subwoofer is connected to an outlet on the
same circuit breaker, provided that the total system
current draw does not exceed the breaker current
rating.

• This arrangement will reduce the possibility of an
audible hum in your system caused by a ground loop.

• Whenever possible, keep the power cords away
from the signal cable or speaker wires to prevent any
hum or inference being heard in speakers.

• Choose reliable, high quality interconnect cables,
also called patch cords or RCA cables. They should
be fully shielded and as short as possible for the job.
The longest cable in your system will likely be to the
subwoofer, so choose a good quality brand.

or you may damage the jacks of the subwoofer or
your other components.

Speaker Level Connections

• The subwoofer's Speaker Level Inputs can accept
speaker stripped speaker wires only.

• Make sure that the negative speaker wires never
touch the positive wires as this will short out and
possibly damage your amplifier or receiver.

System Configurations

The following pages show some typical connections
that you might make in your installation. They show
how the inputs and outputs of the Earthquake sub are
connected to your pre-amplifier or receiver.

Connections to a pre-amplifier's
subwoofer output

If your pre-amplifier has a subwoofer output (often
labeled LFE for Low Frequency Effects), it can be
connected to the subwoofer's Left (Mono) input as
shown. This is the simplest and recommended
connection. A receiver with a sub/LFE output can be
connected in the same way.

The subwoofer will play the low frequency range and
the other speaker will play the frequency range
delivered to them by your amplifier.

If you have a home theater pre-amplifier, it may have
an independent subwoofer volume control. Make sure
this is correctly adjusted, and that the Earthquake
subwoofer's crossover frequency is set to 100Hz. This
is by no means an iron-clad rule, rather it is a good
starting point.

Connections to a pre-amplifier using
“Y” cables

If your pre-amplifier does not have a sub/LFE output,
you can use “Y” cables to send its main outputs to
both the subwoofer and your amplifier.

The subwoofer will play the low frequency range and
your front speakers will play the full range.

Although bass is commonly distributed evenly
between left and right channels (L+R bass), movie
soundtracks often contain differential (L-R) bass. The
opening scene in “Top Gun”, for example, has loads of
L-R bass information. If this is not preserved, the bass
in these scenes sounds anemic. The Earthquake
subwoofer utilized differential gain on the left and right
inputs to retain both the L+R and L-R information.
Therefore, systems which do not have a dedicated
sub/LFE output should use both the left and the right
inputs as shown, for the greatest bass impact.

An Alternative connection method without using “Y”
cables is shown on the next page.

If your pre-amp/receiver has a dedicated sub/LFE
output, the only the Left (Mono) input is used, as
shown on the previous page.

Using the line speaker-level inputs

If you are using a receiver which does not have a
subwoofer output or line level outputs (pre-outs), you
can connect its speaker outputs to the subwoofer's
Speaker-Level inputs. The front speakers can still be
connected to your receiver.

The subwoofer's internal amplifier supplies the power
to reproduce the low frequency range. It receives a
sample of the signal going to your front speakers. (An
insignificant fraction of your receiver's power is
transferred to the subwoofer).

There is no need to use the Speaker Level inputs if
you are using a separate amplifier and pre-amplifier.
Such systems are best connected using the Line
Level Inputs as shown in the previous diagrams.

If you are using the Line Level inputs and there is an
excessive amount of noise or hum present, using the
Speaker Level inputs may yield a lower background
noise level.

Adjusting the controls

There are two main methods for adjusting the level,
crossover frequency and phase of the Earthquake
MiniMe to match a system.

? Method One: Typical: Listening and making

adjustments to suit your taste.

Control settings

Use the following charts to record more desirable data
from test results.

? Method Two: Laboratory: By measuring the

output and adjusting for a flat frequency
response.

Satisfactory results can be achieved if you make the
adjustments based on simply listening. This is
Earthquake's preferred method as it allows the system
to be voiced based on what sounds the best,
whereas laboratory-flat frequency response can often
be clinical and less than exciting.

The following procedure is for those who prefer a
more methodical and scientific approach.

You will need a test CD with low-frequency warble
tones, and a sound pressure-level meter.

Step #1
Disconnect the subwoofer and run the main speaker
with a tone in its passband (80-100Hz). Measure the
level.

Step #2
Disconnect the main speaker and reconnect the
subwoofer. Set the subwoofer to its highest crossover
frequency. Set the level control of the subwoofer to
give the same sound pressure level with the same
tone you used in Step #1.

Step #3
With both the subwoofer and the main speaker
connected, measure the level of the tones at the
available frequencies. Because the crossover is set
too high, you will have a peaked response. Adjust the
crossover control to get the smoothest response.

Step #4
Use the phase control to make the response even
smoother. It has its biggest effect at the crossover
frequency. You can iterate between the crossover and
the phases controls. Keep your hands off the level
control! It was set correctly in Step #2.

Step #5
Listen to the subwoofer. Resist all temptation to turn
up the level control. Play something with really deep
bass to confirm that your subwoofer is working.
