Extremely hard to find are the G2 extension speakers. Introduced in 1966, they were part of the move towards modular stereo systems. Made of sturdy cast aluminium they are small but heavy - weighing about 25 lbs each. Sold separately from the G2 system one could buy just the speaker stands and remove the arms from the G2 and place your now mobile G2 speakers anywhere in the room. New, the speakers cost 90$ each with the bases selling for 25$ each.
