Here are my choices, in no particular order and chosen for the impact and importance of the speaker in its time,not necessarily because it would stand up against the competition today-although several do indeed still sound remarkably good:
1) Quad 57
2) Acoustic Research AR 3
3) Quad 63
4) Dahlquist DQ 10
5) Spendor BC 1
6) Spendor SP 1/2
7) Magnepan MG III
8) Klipsch Corner Horns
9) Large Advent
10) Rogers (or Spendor) LS 3/5a
These are/were all "real world" speakers, i.e., at least within financial reach of quite a few people of normal means, unlike some of the esoterica from Infinity, Wilson, Genesis, Pipe Dreams, etc.
