Default Changing drives is it that stright forward

I am looking to change some tweeter drives on a speaker kit I made a while back. Is it as easy as just getting a better drive's and replacing them, or will some drives only really work with a certain cross over box design and bass/mid unit. What I am really asking is their a bit more science to the whole thing then just getting new drives.

At the moment I have Treble: Scan-speak D2905-9700 soft dome tweeter
90dB ~ 6 ohm ~ 104mm o/dia ~ 44mm deep ~ 28mm vc ~ 225w power ~ 500Hz Fs ~2-30kHz range

Looking at R2904-700000 Ring Radiator Tweeter
94.5dB ~ 4 ohm ~ 104mm o/dia ~ 31mm deep ~ 25mm vc ~ 150w power ~ 520Hz Fs ~ 2-40kHz range

I know it would be a big step up but have been offered them at half the price of new cost, costing about the same as the drives I already have.

You will need to change the xover too. There are times when you can find a drop-in replacement (will work fine with current xover) but most times upgrading drivers will require upgrading xovers if you're doing it properly.

Yes, there is more science to it. And often more black magic to it as well
