If there is an LFE sub in a playback system, that also has full range satellites,. Why not use it? Music playback on these systems can still use the full range, but also use the sub for dynamic effect. Particularly when it is dialled low. It allows the program material to be louder, as one is using all the available headroom. It also doesn't register so much on Dolby meters when cinema broadcast is required. Which also means the volume can be pushed even more. As long as it's used sparing for the very lows, then it won't mess managed systems either…
