Well, kind of answered my own question after looking through some old Audio Magazine Annual Equipment directory. The Virtuoso 6V was manufactured in 1991. If has a 4.5" midrange, a 1" dome tweeter, and two 6.5" woofers. Freq response is listed as 29hz-29khz + or - 3db. Sensitivity is 88db. Listed for $1550 per pair.
They were close so I went ahead and jumped on them, brought them home and wiped them down real well and just hooked them up. They sound great! Wow, can't believe the luck! Each grill was missing one of the four grill pegs but they stay in fine and look better without the grills anyway. The finish has a few scratches here and there but still look quite attractive. Here's a pic of them I just took.
