I'm modding some old Optimus 4 speakers and replacing the two, 16 ohm tweeters, in each cabinet with two EPI inverted dome tweeters. I measure that the EPI tweeters are 6 ohm (am I correct?).

Here's my question:

The two original tweeters were parallel wired to the x-over so there "seen" impedance was 8 ohm which matched the impedance of the existing woofer. Here is a diagram of how the tweeters were wired originally:

What do i need to do to match the two EPI tweeters impedance (6 ohm each tweeter) to the impedance of the existing woofer (8 ohm)?
