Hey. This is probably a stupid question, but here goes (be kind).
I understand the basic principle of the passive radiator, or at least I feel like I do. But there's one thing I don't quite get.
With the excursion of the driver, the passive radiator would move in the opposite direction, correct? When the driver goes 'out,' the PR goes 'in,' right? I assume that, in addition to adjusting for cabinet volume, the PR will also produce some sound as it moves in inverse proportion to the driver.
So effectively, wouldn't they be acting in opposite polarity (i.e. 'out of phase') with respect to one another? How does this keep from harming the overall sound due to destructive interference?
Is this why some PRs are mounted on the back of the cabinet?
Maybe someone can clue me in. Thanks!!
