I have look far and wide (on the web), and have came up with NO info on them, I have emailed Wharfedale in England, and they said that the warehouse that they stored all the documents on vintage speakers burnt down....and all the people who worked for Wharfedale at the time of the speakers (1981) have long since retired. If ANYONE has any info: Specs,.....anything! Please help me out! Product: Wharfedale Series Mach 9 floorstanding speakers, produced 1981.
