Bose 901 Series ii

Oh, and rather than stack the 901's, I'd place one pair on the floor with the Bose 901 stands and hang the other pair from the ceiling.  (901's MUST be used with the Bose active equalizer - it would be near impossible to replicate the active eq as it perfectly creates an exact opposite frequency curve of the drivers which are mid-range efficient).

I had 901's as did many of my friends while I was in high school and early college.  The best match for the 901 speakers I heard then were Marantz preamp paired with Marantz power amp. Very "tube-like" and delicious mids.  The overall presentation was very, very good with a pair hanging and a pair on Bose pedestals. 

archimedesaz, in an empty room you would have 2 up front and 2 on the side. this was called the "super bose system" back in the 70's. the 2 up front was the soundstage. the 2 on the side brought the soundstage to the side. i have this today but i have my 4 hanging from the ceiling.
