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

Subwoofer Setup
Step 1
INPUTS: Your subwoofer has three 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.
BALANCED XLR INPUT: If your receiver or preamp-processor has balanced XLR subwoofer line-out connections, you may
connect a Balanced XLR male connector to the XLR female input on your subwoofer.
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
LOW LEVEL OUTPUT (RCA or XLR Balanced) : 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, XLR Balanced, or 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 pre-amp processor turn the
subwoofer crossover control to 150 Hz. If you are using the HIGH LEVEL (Speaker Level) binding-post inputs, set the subwoofer
crossover switch to 80 Hz for any of our bookshelf models or 60 Hz for any of our oor-standing models. Since every room and
subwoofer location in it will react dierently we suggest you try some other crossover seings as well, for example 40 Hz with a pair
of M80s. You may nd that the best sound in your room is achieved using a slightly higher or slightly lower crossover seing to our
suggestion above.
Step 4
VOLUME : Set the volume to 1/2 turn of the rotation range. Later, during the set up process, you will likely return to this volume
seing to balance the output of the subwoofer to the other speakers. Your receiver may be equipped with an auto-setup feature.
ese are very convenient but will not always give you the most optimum audio quality in your room. If you have the time we
would suggest doing your set-up manually. You can always compare your manual setup to the auto-setup to see which one you
prefer. Aer your initial set-up is complete, whether manual or auto, you may nd you want to turn your subwoofer volume up or
down a small amount aer listening to a variety of source material. 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 (T6.3AL for 115V and T3.15AL 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 change from Green to Red 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
PHASE and POLARITY: 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 rotating the phase dial in 1/8 turn increments starting at
0 until you reach 180 and then switch to Polarity to 180 and repeat the process to see if one of these seings produces deeper and
smoother bass output in your room. Once complete, move the dial back to the position that resulted in the smoothest and deepest
bass at several listening locations in the room. If you hear no dierence, leave the dial and the polarity switch at the 0 position.
Quite oen the phase dial and polarity switch makes lile dierence, but it’s dependent on your particular room’s dimensions and
subwoofer location.
Step 8
SUBSONIC: Seing this switch to “ON” inserts a 20-Hz cut-o lter in the subwoofer’s bass response to prevent the subwoofer
from reproducing frequencies below 20 Hz, which may include rumble from studio air conditioning, subways or other undesirable
artifacts. If you play vinyl discs from a turntable, set this switch to “ON” to prevent the subwoofer from reproducing turntable
rumble and low-frequency record-warp anomalies.
Leave this switch set to “OFF” for all other digital recordings and DVD sound tracks that contain ultra-deep bass frequencies you
want the subwoofer to accurately reproduce.
Step 9
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 1-888-352-9466 for technical support.
POWER INDICATOR: e LED Power indicator glows Green when the subwoofer is powered on and Red when a trigger signal
is connected and in the “o” mode
