About a year and a half ago I purchased a Polk Audio PSW-404 powered sub.I really like it but I have just gone through my 2nd driver.Which they are replacing at no cost to me.The person I talked to said it must be the volume level is turned up too far.I don't have the level any more than about 3/4 at the most.Besides this sub "should" be able to handle pretty much anything thrown at it shouldn't it?The other thing I noticed is the the cooling fins in the back seem pretty warm to me even if it's just been sitting around all day not being used just on stand by mode.Is this normal?
Thanks for any help.
