Hitachi HS-25G tweeter replacement

Hello,
I’ve just bought a pair of Hitachi HS-25G speakers and one of the tweeters is blown so I need a replacement.
The problem is I’m unsure where to find one and would appreciate any pointers in the right direction.
On the tweeter are some specifications (written below).
