That's not correct... the OEM tweeter high pass filter is at the tweeter itself. Remove that tweeter and the filter goes with it.

My budget is around $200 for the whole system but $100 for a pair of speakers and tweeters seems like a really good deal.
For $200 you can get a pair of Rainbow components, which it would be the really good deal.

Regardless of the speaker that you choose, you OEM amp will expect 2 ohms of impedance on those channels. The vast majority of the aftermarket 4" that fit your E90 are 4 ohms, so you will notice that the new speakers will not sound as loud as the OEM at the same volume levels.

You may or may not like the results, depending on your expectations for those $200.
