@judah Yes and no. Yes, because the low end is often not musical, and just adds a DC bias, reducing headroom. But for subs, I can can get pretty clean down to a low C (33Hz) on my system. If I cut at 35, I'll lose a lot of that. For other sounds, like pads, you usually only want the mids and treble, but those sounds often still include a lot of low-end information (I've seen samples with heaps of 10Hz content) that will mess with your bass and low mids. Cut them much higher to avoid low-end mud.
