Any info about Maston Audio?

I own a pair of Maston Audio Satellite speakers that date from about 1990. They are built with MB Electronics MCD-25 tweeters and Dynaudio 17W75XL bass/midrange drivers. I'm interested in any information about the company, its products or where to find replacement drivers. I know that they were located in the San Jose, Ca. area and were in business from approx. 1990-1993.

Any help would be greatly appreciated!
