Know anything about these?

I've searched the net for technical specs for these speakers and I haven't found anything. Can anyone please help me with that?

FWIW, looks like they got reviewed in the February 1987 issue of Stereo Review magazine according to Roger Russell's site:

SR 1987 Volume 52 Numbers 1-12
February 1987
JVC XL-M700 CD changer
Mission 780 Argonaut speaker
Technics SA-590 am/fm receiver
SAE P102 preamp
Altec Lansing 401 speaker

And the components brought small change here:

But you probably found all that already. Google didn't have much else to give.
