I'm sure others will chime in on this, but I think the majority of people use 80hz. Some like 60hz for music and 80hz for movies. Some use higher than 80hz, not sure I see that point. Your right the 60's will go much lower than 80hz, but it is my understanding there is a gradual slope/blend once it hits 80hz, it just doesn't cut off. I know my Denon manual recommended this as does THX, but what do they know
