What should I buy to measure Frequency of my Subwoofer in my car and also I'd like to know the decibels output.
Do I need two devices or are there ones that will do both in one unit?
I think this unit just measure decibels?
Somebody on the Nissan Leaf forum asked me this:
"To start with - analytically - how flat is your response curve and to what Hz at the low end ? If you haven't checked, get hold of a stereophile cd & a simple dsl meter from ratshack and try it out. You will be surprised."
I'm not sure how to measure these items,
