Below is all the information I have found or have on the Mission 76x speaker line including specifications and some photos.

The Mission 76x speaker line was made in England by the Mission Cyrus Group and distributed in North America by Mission electronics INC in Vancouver Canada and was manufactured between 1989 through 1992. Information seems to be very hard to come by now as well as parts.
Some have said that this and the 75x line were Missions best speaker lineup particularly the 764-767
If you are looking for parts you can contact the only Mission sales contact I have found AUDIONINE in Toronto Canada by email

The 767s required a special external crossver (LFAU) along with the Cyrus amp in order to run them properly and are very hard to find.
"The Low Frequency Alignment Unit (LFAU) was originally designed around the award wining Cyrus II integrated amplifier for the primary use with the Mission 767 loudspeakers. The LFAU was a dedicated amplifier for the bass units of the 767 and the remainder of the units were controlled by a standard integrated amplifier. The controls on the LFAU differ from those of a standard amplifier as the bass response of the 767 system could be fine tuned to suit the listening environment."

Thanks to a member this article and this one was brought to my attention on the difference between the original 760 and the improved 760i and may be useful to other readers.
