Yeah, those look like the exact pictures I saw. Still not seeing where they come up with tri pole.
The only company I can think of that marketed a "tri-pole" speaker was Miller & Kreisel. Most everyone else made a di-pole, bi-pole or a "multi-pole" which is switchable between the 2 modes of operation, some even allowed for a 3rd mode depending on the driver configuration. the third mode being DIRECT radiating. Cambridge Soundworks Newton S300 comes to mind
The pictures lead me to believe that these are di-pole ( more ambient/diffuse, and less direct) The "R" sticker might indicate right speaker since dipoles have a definite left and right speaker to maintain proper phasing in the system.
or something along these lines
