If you zoom into your waveform you can see that it doesn't cross zero (middle) very often - the higher frequencies modulate up and down as a whole. That's not supposed to happen. With one take and on smaller speakers you may not hear much of a difference but the huge amount of low energy is coming from somewhere and is a major problem later on. It has nothing to do with mic technique I don't think. It seems like a technical or electrical problem. A normal looking wave crosses through zero with every fundamental (lowest frequency oscillation). Your fundamental is around 25Hz but your actual voice doesn't get below, say, 100Hz. Look at the audio clips in this link:

Do you see how yours look different?
Can you try a different mic cable? The second input on your interface? How many power points are in all your connected gear (speakers, computer, interface etc) and how are they hooked up (single socket with an extension, multiple wall sockets, grounded or not etc).
