HELP Platinum Audio Solo...., HELP PLEASE,

I need to know who manufactured the drivers for the Platinum Audio Solo loudspeakers, so that I can replace them !!
Also, I happen to have a pair of Scan-Speak ring radiators that I may consider using for the tweeters.
What would be the BEST match for the lower end.

Thank you,
KM Schaefer

PS. Any and all help on this subject will be greatly appreciated.

Thanks again
Karl
