Sony didn’t sell the biggest or loudest boomboxes in the world, but they were well made and their sound was terrific. This CFS-77 was no exception–it was sold up to 1983 and had most unusual floating tweeters positioned in front of the speakers. Sony was of the opinion that “less is more,” evidenced in the sleak shapes of their walkmans and televisions. We see this in the narrow CFS-77, CFS-99 and CFS-500.
