I can talk about this a little bit. Middle notes (for most people) have power because they are optimized in terms of resonance. The cords vibrate at close to full length. A long vibrating body has more timbral complexity since it has a fuller array of partials as compared to a shorter vibrating body, which still must top out at the upper range of human hearing, while missing out on the lower frequency bands (except for some difference tones, which are not very strong). Did that make any sense at all?
The highest notes are technically less complex, but carry best because the high partials created by them are lower order in relation to the fundamental, meaning higher relative amplitudes to the same band created by a lower fundamental. Since the high band is where the "ring" is, high notes tend to produce a more prominent "ring" and thus carry better.
The reason low notes are not that powerful (for most people): The only way that already full length cords may produce lower pitches is to slacken a bit. Looser means softer (like baroque strings) and again, less timbral complexity. Larger men like Krause and Moll can get past this since: A) they probably have longer, thicker cords in the first place (lower native frequencies) so the cords don't have to slacken until they get really low and B) larger resonant spaces to allow the lower partials to find a home, enriching the fundamentals.
Most men can slacken their cords to "Slavic" depths, but building an operatically convincing resonance upon those notes is another matter... I was originally misdiagnosed as a bass because I could do this (and I hadn't discovered my head voice) but I have never been able to project in that range.
Hope this helps!
