Monitor 4 Help?

I've read that the 4.5 version of the Monitor 4's have the Silver Coil Dome Tweeters that are almost identical to the Monitor 5Jr's (which I have as surrounds) except the same enclosure. Is it possible to change out the crossovers and tweeters in the Monitor 4's to upgrade them to the 4.5 status? I'm also seriously interested in the CSi A6 center channel to go along with my SDA II's because I hear that having one with my SDA's would be a lot better for voices and is voice-matched with them. Anyone selling one for under $150? After seeing them sell for $130 and $20 shipping, I lost interest in getting them for $190 shipped (I'm such a cheapskate).:rolleyes: $40 can be put toward my new projection screen I need to make or upgrading the Monitor 4's or upgrading my tweeters or crossovers, Blu's, ect.:D

Ive often wondered about this myself. The first pair of polks I bought were the 4.5's back in 87', I was 18 and still in high school(and still have and love them). In my manual the cover photo shows the 4.5's with a silver coil tweeter, BUT the speakers did not have them equipped, and on the last page that shows all the specs of the monitors it lists the 4.5's with the polymer tweeter that the 4a has.

Anybody else know if this is possible?
