Well I did purchase them, the mystery is solved regarding the type, they started off in life as type kdfr's as that's all the original owner could afford, after purchasing he modified the cabinets to look like type B's and 40 years later refinished them in cherry veneer as the pictures above show, all the parts & drivers are original. currently I'm using a cheap chip amp with crappy speaker wire and they still sound impressive, the high end is a bit shrilly, not sure if its the amp or the old crossovers or maybe even the squaker. Glad i got em, & i appreciate all the feedback & comments, I'm in the middle of a trade for some pro audio gear so hopefully I'll have proper amps, preamps & such soon. The mcintosh Ma6100 integrated i thought i was gonna used needs work from sitting in storage so long.
