Reply to Replacing the Tweeters in my PA Speakers

Hey all,

Normally I'm pretty good with replacing my sound components, but I've run into a bit of a problem, mainly due to lack of information on the particular component. I have 2 Phonic S710 PA speakers (tiny little things, hate gigging with em but they do the job for house parties) and one of the tweeters has blown out. Now I've never gone about replacing the tweeter (woofers have been re-done, good on that), is it similar to replacing the woofer (i.e. match wattage/impedance/etc)?

Any help would be appreciated.
