I don't think they are TT "bantam"...I ordered a set (non refundable...anyone want to but them...?). The TT connectors are indeed much smaller. The ones I'm trying to figure out (the attached pictures) are much larger, looks much more like a 1/4" connector. I asked the tech at the theater, and he said "...they are some sort of military connector..." but couldn't tell what kind, where to buy, etc... but he said they are not 1/4" TRW standard. I'm still puzzled.
