Hi,

I got a pair of these recently for a sound system for my basement music room. I think they are A7 but not sure which version or when they were made.

I think 1968 or 1978 due to date codes of "8" on the speakers. Has
802D 16ohm 15", horn drivers 391831 836 416.

Any info appreciated, thanks!

p.s. this is how they showed up:
