I am confused. Does the crossover on the EP500 have any effect when using the line in? I thought it only came into play with the High Level Input.
It doesn't make sense to have a crossover on the line in, I would want the EP500 to play everything it gets from the receiver after it is crossed over by the receiver.
I would agree with you. The issue involves which configuration best blends the speakers and sub. What is unique with the EP subs is the steep brickwall filters unlike the gradual 12hz, 18hz or 24hz/ octave rolloffs found in most subs. While there may be some speakers and rooms that may benefit from these "cascading" crossovers, I would avoid engaging both filters because of the likelhood of creating phase anomolies and other artifacts.
