Service and Troubleshooting 

M&S Systems is committed to producing high quality 

products for the home. If you have any questions or 

problems with your subwoofer or if it is not operating 

properly, contact your M&S installer or call M&S Systems 

at 1-800-366-9422 and speak with one of our technical 

support specialists. 

You may also visit our web site at

for a frequently asked questions list that may provide you 

with quick assistance with any troubleshooting or service 

concerns. 

After carefully unpacking your subwoofer, the carton and the 

packaging material should be saved for possible use later.  

To attach the feet to the subwoofer, lay it on its top with the 

speaker facing up. Remove the feet from their package and 

screw them into the pre-drilled holes located on the bottom of the 

subwoofer with a screwdriver. Once the feet are tightly secured, 

place the subwoofer upright on its feet. 

If the subwoofer appears to be damaged, do not attempt to 

repair or connect the unit to the amplifier. If you have to return 

the subwoofer first remove the feet, then repack the subwoofer 

and notify your distributor or M&S Systems for replacement or 

repair.  

You can contact the M&S Customer Service team at 1-800-877-

6631.
