Speaking of which, I'm actually considering swapping out the drivers on the VP180 and replacing them with v4 drivers. Would it be a simple as just swapping out the 6 drivers? On the parts page they also have the crossover listed, but there is no version associated with it, so I'm assuming the crossover is the same.
