it's practically impossible to have a perfect cutoff at the upper and lower boundaries...thus, roll off is sloped...if they wanted the slope to end at 20Hz, it would have to start at a frequency above that and thus you'd be rolling off through part of the audible range. If you push the end of that rolloff back to 6Hz, you're more likely to have less rolloff around the 20Hz range and thus, the audible ranges will be preserved with a relatively flat frequency response. And yes, this is old! lol
