Okay, I am going to resurrect this thread to clear up some of the confusion that people seem to have regarding the Kenwood Eleven series.
There are at least the following:
Kenwood Model Eleven (Mark I - 1975) 60WPC
Kenwood Model Eleven II (1976?) 80WPC
Kenwood Model Eleven III (1977) 120WPC
These were also sold under the Kenwood KL-10000 (Mark I, II, III) with a bronze / champagne face instead of silver.
Then there was the Kenwood Eleven G and Eleven GX in standard brushed aluminum. (1978) 120WPC
These were mirrored by the Kenwood KR-11000G, and the KR-11000GX, which I believe are identical and featured darker gunmetal faces.
Lastly there was the Kenwood Super Eleven, which featured a black face and some early 1980s visuals with its reverberation display. (1980) 125WPC.
I think that is it for the Eleven series, there was also the Nine series which I think were about 80WPC territory mostly, and only limited selection by comparison.
If anyone knows more, please chime in!
