I would say iconic in that the JBL L100 is immediately recognizable by nearly everyone who was into audio systems in the 70's and 80's. There's no denying the L100 was a very popular speaker in its day.
I found the video rather humorous, especially when the OP said he drives his new L100 Classic speakers with a $250.00 Crown amp. I think there's some advances to be had there. At any rate, I haven't heard the L100 Classic but I would enjoy the experience if for nothing more than nostalgia. I owned a pair of JBL L100's back in the day and played the hell out of them before ultimately giving them to my brother.
