JBL L100 loudspeaker, the speaker that truly defined the sound of the 1970s. Why? It's the home version of the JBL 4310, the most popular studio control room monitor at the time. It became simultaneously the most common audiophile speaker and the monitor used to mix the most hit records.
Altec's ad for this speaker drew controversy in the more conservative values of mainstream 1970s American culture. Some magazines wouldn't run it. My, how times have changed!
