DBX Soundfield V tweeter replacement

Being non-tech about speaker drivers, would I need approximately the same hi-freq driver wattage as what floor speakers rated at? No longer care for OEM ribbon tweeters.

I have owned these DBX speakers since I bought them new 20+ years ago, they are rated at: 250 watts, doesn't state whether RMS or continuous.

I would contact Madisound.
Buy new speakers. Trying to fit a non-OEM tweeter will result in a sonic nightmare...
