Every member of our Axiom team, myself included, is pleased that you have decided on one of our products.
We have all worked hard to bring you the highest level of satisfaction from your audio experiences, and will
continue to work hard to make every Axiom purchase a wise audio investment for you.
Axiom is deeply committed to ongoing audio research that continues to enhance the performance of our
products. We design and engineer all of our loudspeakers based on the world-class psycho-acoustical
research that was conducted at the National Research Council and that I have been an integral part of
since its early years. This research changed the way the sound is measured, and allows Axiom to provide
the world’s most realistic-sounding loudspeakers at amazing value to the consumer. By emphasizing the
practical side of our ongoing research, Axiom continues to extend people’s expectations of performance.
It is our central goal at Axiom to turn this research into a truly exciting experience for you in your environment.

FOOT INSTALLATION
Install the four rubber feet with the supplied screws or install the
spiked feet, tightening securely in the inserts provided at the bottom
of the speaker.

EP175 ELECTRICAL CONNECTIONS
Step 1:
LINE IN: the RCA line-level female input, second row, accepts a
standard RCA male plug. Connect a shielded coaxial cable, with
male RCA plugs on each end, from the A/V receiver or A/V preamp
processor’s Subwoofer Output jack to the RCA LINE IN female jack
on the EP175.
3.5mm MINI-Jack: this is for any 3Volt to 30Volt power on trigger.
It is also intended for trigger-controlled operation with future Axiom
products.
BALANCED XLR LINE IN: if the A/V receiver or A/V preamp-
processor has balanced XLR subwoofer line-out connections, you
may connect a Balanced XLR male connector to the XLR female
input. Otherwise, ignore this connector. Do not use a combination
of RCA and XLR input or output connectors.
HIGH LEVEL INPUT: Use these “speaker-level” or high-level 5-way
binding post connectors only if your receiver or preamp lacks a
dedicated line-level subwoofer output jack. Connect speaker cables
from your amplifier’s left-channel and right-channel speaker output
binding posts to the high-level inputs using banana plugs (single or
dual), spade connectors, pins, or bare cable if you wish (unscrew
the top of each binding post and insert the cable into the hole in the
post; tighten the knurled knob against the cable). Run a second pair
of speaker cables from these jacks to your main left and right front
speakers. Do not use these connectors if you are already using an
RCA or XLR line-level connection from the receiver or preamp to the
subwoofer. NOTE: BE SURE TO CONNECT BLACK TO BLACK
AND RED TO RED.
Step 2:
LINE OUT (RCA, Trigger and XLR Balanced):
An RCA line-level (female) output and balanced XLR output (male)
are provided for connection to a second subwoofer. Use a standard
shielded coaxial cable for connection of the RCA Line Out to the
second subwoofer. If you are using balanced XLR connectors, then
use the balanced Line Out for operation of a second EP175.
Step 3:
CROSSOVER: if you are using the Bass Management crossover
menu settings in your A/V receiver or processor, turn this control
to “BYPASS” to eliminate the EP175 internal crossover from the
circuit.
If you are using the HIGH LEVEL (Speaker Level) binding-post
inputs, set the crossover switch to 80 Hz for initial setup. If you
have floor-standing speakers (M40, M50, or M60), try a 60 Hz
crossover frequency, for the M80 try 40 Hz. If your main speakers
are bookshelf models M3 or M22, try the 80 Hz setting, for the M2
try 100 Hz. Ultimately you want to use a crossover frequency that
produces the smoothest blend of sound between the subwoofer and
your main speakers.
Step 4:
VOLUME: Set this midway to the 9 o’clock position for initial setup.
You can use this to manually regulate the subwoofer volume at
any time and during your initial setup adjustments with the other
speakers in your stereo or home theater system.
Step 5:
ON/OFF AC POWER/VOLTAGE SETTING: Your subwoofer is
supplied with a pop-out voltage regulator set for use with 100 - 120
volts from the A/C line. It can be easily removed and turned over to
set your EP175 to 220 volts from the A/C line.
Once you have made appropriate connections from the A/V receiver
or preamp/processor to the EP175 and set the voltage regulator
to the proper voltage, find a nearby AC wall outlet and connect
the main power cord to the three-wire socket at the bottom of the
control panel. Move the power switch to the ON setting and the LED
POWER indicator should glow Green. Leave the switch at the ON
setting unless you go away for an extended period. Moving it to OFF
will shut down all power to the subwoofer.
Step 6:
0 & 180 PHASE: This synchronizes the in/out movement of the
subwoofer cone driver with the other speakers in your system. Once
you have chosen the best location for your subwoofer, try flipping
the phase switch between 0 and 180 to see if one or the other setting
produces deeper and smoother bass output in your room. Leave the
switch at the setting that results in the smoothest and deepest bass
at several listening locations in the room. If you hear no difference,
leave the switch at the 0 position. Quite often the phase switch
makes no difference, but it’s dependent on your room and subwoofer
location.
Step 7:
GROUND LOOP:
If your subwoofer is producing a 50 or 60 Hz hum; remove the
Chassis Ground Screw. If this does not solve the hum, call 1-
866-244-8796 or consult the full manual at www.axiomaudio.
com/epmanual.html
POWER INDICATOR: The LED Power indicator glows Green
when it’s on and Red indicating Standby Mode.
Please Note: The EP350 will shut down if heavily over drivenin
into distortion. To reset, turn power switch OFF then ON.

The exclamation point within an equilateral triangle is intended to alert the user to the presence
of important operating and maintenance (servicing) instructions in the literature accompanying
the product.
The lightning ash with arrow head symbol, within an equilateral triangle, is intended to alert
the user of the presence of un-insulated “dangerous voltage” within the product’s enclosure that
may be of sufcient magnitude to constitute a risk of electric shock to persons.
SAFETY PROCEDURES
• Ensure that you connect your Subwoofer only to the type of power supply indicated on the
amplifier faceplate, and ensure that the power cord cannot be walked on or otherwise damaged.
• To prevent electric shock, match wide blade of plug to wide slot, fully insert.
• Ensure that objects or liquids are not allowed to penetrate the enclosure.
• Your AXIOM Subwoofers are finished in a durable vinyl and from time to time should be wiped
clean gently with a slightly damp cloth to remove any dust or stains.
