i dont think it matters,,as a matter of fact most speakers for the home use different driver brands for tweeters/mids/woofers.
My tweeters are an older model from Vifa D26NC-05 ....they have been replaced already by a different one (they are 6 ohm)
The Peerless are the 850518 (4 ohms)from the CSC-X line (auto)
