Section 6—Proper Care and Feeding 

 

Your Rocket UFW series subwoofer does not 
need much exterior maintenance other than an 

occasional dusting.  Please use care with the 
gloss black ends and treat them as you would a 

piano finish.  They can be waxed with automo-
tive carnauba wax if desired.  We recommend 

the 3M Yellow Detail Cloth (part # 39016) for 
dust removal as it will not scratch the black sur-
face.  The durable matte finish on the wood ve-

neer requires only some dusting, or can be wiped 
off with a water dampened soft cloth. 

 
Above all, listen and enjoy!
