I just turned 50 years of age this past August 4th. With that being said, I think that the commercial is just fine. JBL is targeting a much younger audience that was never into stereo equipment. Maybe there were curious about it but just didn't know where to start and JBL took that critical first step for them and won.
By the way, I was at my local Best Buy last week and I saw the JBL receiver. Looks very simple. Crutchfield has it on their site too.
