Placement
e amount of deep bass you get from your new subwoofer will be quite dependent on proper location in your particular room, the
room’s dimensions, and the location of your listening area. You can’t easily change your room or its dimensions, so it’s worthwhile
nding the best location that will let your subwoofer deliver its optimum performance---smooth, deep and powerful bass to your
seating area. e subwoofer does NOT have to be at the front of the room with your main stereo speakers. Deep bass below 80 Hz
is not directional, so it doesn’t maer if the subwoofer faces you or is at the side or back of the room. Now get ready to do the tried-
and-true “subwoofer crawl.” Move your subwoofer as close as you can to where you sit. If it’s a chair, move the chair aside and place
the sub where the chair was. If it’s a couch, slide the couch temporarily out of the way and put the sub about where you usually sit.
Play a DVD movie with lots of low-frequency eects or a CD with plenty of deep bass in the music, the kind that really kicks your
sub into motion.
Now crawl around the room in the general area where you were thinking of locating the sub or even in areas that you didn’t think
of. Go several yards in each direction--near the wall, out from the wall, towards a corner, away from the corner, and so on on all four
walls--while you listen for smooth and extended bass response. At some locations, the bass may seem really exaggerated and boomy.
In other spots, it may almost disappear. Pick a location somewhere between these extremes. at’s it! Mark the spot with some
masking tape then move the subwoofer into that position. Now put the furniture back.
Test the technique by playing the same deep bass selections, only this time sit in your favorite chair (where the subwoofer was). e
deep bass should sound just like it did at the place where the sub now sits. You see, it works!
Every member of our Axiom team is pleased that you have decided to purchase one of our products. We have all worked hard to
bring the highest level of satisfaction to your audio experience.
Axiom is deeply commied to ongoing audio research. It began in the early 1980s when I was involved with the world-class psycho-
acoustical research that was being conducted at the National Research Council in Oawa, Canada. Since that time we have built
one of the nest acoustical laboratories in the world at our facility in Dwight, Canada where we continue this research allowing
Axiom to provide the world’s most realistic-sounding loudspeakers.
At Axiom our goal is to provide you with a truly exciting and emotional experience every time you listen to your audio system. We
want you to feel part of our Axiom family and as such we stand at the ready to deliver personal, expert advice on any of your audio

Subwoofer Setup
Step 1
INPUTS: Your subwoofer has two options for input connection. Do not mix these inputs; whatever output you are using on your
receiver or pre-amp needs to be connected to the same input on your subwoofer.
RCA LOW LEVEL INPUT: e most common input method is the RCA jack. Using a standard RCA cable hook this input to an
RCA sub output jack on your pre-amp processor or receiver.
HIGH LEVEL INPUT: Use the “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 amplier’s le-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).
You can run the speaker cables either to the subwoofer rst or the speaker rst. NOTE: BE SURE TO CONNECT BLACK TO
BLACK AND RED TO RED.
Step 2
RCA LOW LEVEL OUTPUT : If you are using more than one subwoofer the line out allows you to connect one subwoofer to the
next around your room. Be sure to use the same cabling method as you have used from your pre-amp or receiver. Do not mix the
RCA and High Level when daisy chaining multiple subwoofers.
Step 3
CROSSOVER : If you are using the Bass Management crossover menu seings in your A/V receiver or processor, select the 150
Hz seing on the subwoofer.
If you are using the HIGH LEVEL (Speaker Level) binding-post inputs, set the crossover to 80Hz for initial setup. If you nd the
subwoofer is not blending well with your main speakers, try the 150 Hz seing.
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 the volume to 1/2 turn of the rotation range. Later, when you have nished the hookup of your subwoofer, you will
return to this volume seing to balance the output of the subwoofer to the other speakers. Avoid the use of the auto-setup feature in
your receiver if it is equipped with one. ese devices rarely work properly. If you do use auto-setup, be sure you set the subwoofer’s
volume control to 1/2 rotation; otherwise, some receiver’s auto-setup circuits will set the subwoofer volume too low. If that occurs,
try raising the A/V receiver’s subwoofer output level in the receiver (also called “LFE” for Low Frequency Eects). You can increase
the LFE (Subwoofer) output level in the receiver’s setup menu by +4 dB to +6 dB above the 0-dB level to obtain proper subwoofer
output level. e best method is to balance your sub to the other speakers using a variety of music you are familiar with. Seing up
sub levels and proper sub placement in your room can be tricky but worth puing some eort into as the results will be signicant.

Step 5
AC INPUT : Your subwoofer is supplied set to either 115 volts or 230 volts depending on the country we shipped it to. If you
move countries, this voltage can be changed by having a technician change the fuse type (T3.15AL for 115V and T1.5AL for 230V)
and move a cable inside your subwoofer amplier to the plug marked with the desired voltage. Residents of some other countries
will need to purchase an adaptor or new proper power cord that ts your specic socket.
Once you have made appropriate connections from the A/V receiver or preamp/processor to the subwoofer, nd a nearby AC wall
outlet and connect the main power cord to the three-wire socket at the boom of the control panel. Move the power switch to the
ON seing. e LED POWER indicator should glow Green. Leave the switch at the ON seing unless you go away for an extended
period. Moving it to OFF will shut down all power to the subwoofer.
Step 6
TRIGGER: Use of the trigger input is an optional hook-up. If your A/V receiver or A/V preamp-processor has a 12-volt trigger
output, you can run a 3.5mm connector cable to the subwoofer trigger input and your subwoofer will power on and o with your
A/V receiver or A/V preamp-processor. When the trigger signal is in the “o ” mode the LED will turn o and the amplier will be
switched to a low power consumption standby mode. If you have multiple subwoofers you can run a 3.5mm connector cable from
the trigger out on the rst subwoofer to the trigger input of the second subwoofer.
Step 7
0 & 180 PHASE: is 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 ipping the phase switch between 0 and 180 to see if one or the
other seing produces deeper and smoother bass output in your room. Leave the switch at the seing that results in the smoothest
and deepest bass at several listening locations in the room. If you hear no dierence, leave the switch at the 0 position. Quite oen
the phase switch makes lile dierence, but it’s dependent on your particular room’s dimensions and subwoofer location.
Step 8
GROUND LOOP: If your subwoofer is producing a 50 or 60 Hz hum it is likely due to a ground loop. is is caused by a
dierence in potential between the grounds of your receiver or pre-amp and the subwoofer through your house wiring. If this
occurs remove the silver Chassis Ground Screw. If this does not remove the hum, call 1-866-244-8796 for technical support.
POWER INDICATOR: e LED Power indicator glows Green when the subwoofer is powered on and turns o when a trigger
signal is connected and in the “o ” mode
