By "cutting through" I am specifically talking about speech intelligibility, and thanks to my background in pro audio and sound reinforcement, it is a topic I know quite a bit about. Sound systems that must provide speech intelligibility in difficult environments are carefully designed to limit the low frequency response. Three reasons. First, the lower octave bands make very little contribution to speech intelligibility. Second, the lower octave bands are most subject to the effects of reverberation. Third, the lower octave bands burn power that could be better used on the spectrum that does provide intelligibility. The only part of the above that doesn't apply directly to radio communications is reverberation. Note that no one is recommending excessive modulation or processing, which certainly does degrade intelligibility. The K3 can very easily be set up to limit the audio bandwidth, shape it to provide pre-emphasis for the bandwidth lost due to IF filters, and provide dynamics processing (compression). And it sounds VERY good when done properly. I'm coming at this from the perspective of an audio professional and a radio professional.
