Thanks to Oliver and all who replied but unfortunately got these wired up and both tweeters have blown as well as the foam being shot a real shame because they look so beautiful.
I'll be taking them back on Wednesday to the Charity shop but if anyone local to me in Hove fancies taking them on as a project they are yours for the £30 I paid.
So I'll keep looking and am also thinking of perhaps going down the diy route.
