I agree with Sean. Call and ask Mad and PE. You basically want to get something that is close to what you are taking out and/or study up so you can make appropriate changes which can be challenging. The existing tweeter was likely matched with a pad (to level match the sound volume) and crossover (control roll-off)to match it to the woofer. Nothing sounds worse than asking a tweeter to go lower than it wants to.
Did you read the primers on speaker and crossover design at partsexpress? My recollection is that they are fairly good. They spell out the basic issues.
Also if you ask at a diy speaker board like the Madisound forum or diyaudio.com you might get someone with experience right on point. This can't be the first of these tweeters have been replaced.
Sometimes (most) you cannot trust the mnf. numbers.
I remain,
