Mystery Fisher Stereo speakers

Trying to ID the model for these Fisher
floor speakers, so far no luck.

So far closest match is a DS-176

but this seems to be unique due to the 2 controls near the
response chart.
Speaker Terminals are the red/black press type.
I have a post on AudioKarma site but so far no ID.
