    I have my subwoofer hooked up with EQ to make bring out the lower frequencies. Now the thing is when it is hooked into the EQ it makes a slight humm noise which is only noticeable when your down by the subwoofer. Is this something to worry about or am I ok?

    And the subwoofer is a Polk Audio PSW250.

    What is the EQ and how is it connected? Is everything plugged into the same outlet?

    Most subwoofer equalizers work best when used to reduce peaks, rather than boost valleys. I don’t know the specifications on your sub, but it may be that you are trying to boost it past its abilities.

    Hmm, well should it even be doing it when nothing is going through to the sub channel? Could it perhaps just be extra noise from power going through the cable that should not be there?

    I would say the lowest this sub can go is about 30Hz, maybe 25Hz if lucky and positioned right. I have the volume on it up about half way, and have the 31Hz on the EQ almost maxed, the 50Hz up as well, and the rest are up just a tad... It sounds good but I don't want to blow the woofer.

    Do you have a line conditioner? When I plug my SVS right into the wall outlet it hums, but not when it's plugged into the line conditioner. Maybe that's it?

    No line conditioner but there is no humming noise when it isn't plugged into the EQ. Without the EQ everything is alright but unfortunatly it is too boomy at some ranges.
