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:  The 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 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).  

You can run the speaker cables either to the subwoofer first or the speaker first.  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 settings 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 floor-standing models.  Since every room and 

subwoofer location in it will react differently we suggest you try some other crossover settings as well, for example 40 Hz with a pair 

of M80s.  You may find that the best sound in your room is achieved using a slightly higher or slightly lower crossover setting 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 

setting to balance the output of the subwoofer to the other speakers. Your receiver may be equipped with an auto-setup feature.  

These 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.  After your initial set-up is complete, whether manual or auto, you may find you want to turn your subwoofer volume up or 

down a small amount after listening to a variety of source material.  Setting up sub levels and proper sub placement in your room can 

be tricky but worth putting some effort into as the results will be significant.  

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)
