Yeah, I have swapped both tweeters out with the tweeters from my vp150.

I watched some movie trailers and Skyfall last night, sounds to me like the crossover isn't preventing the lower frequencies from being passed to the tweeters. I went ahead and disconnected them as it is just too bothersome.

So it looks like it really has to be the crossover.

On a side note, watching Skyfall with the EP500 is just crazy, better than in the theaters!

Does anyone else who has the EP500 or above find it to be too much for most music? I have another sub(DEF Tech) that I usually use when listening to music, I feel like I get a better appreciation for M80s with less over the top bass! Just reserve the EP500 for movies!
