I would've thought the 105mm howitzer would make a louder bang?

Yep I thought the 105 was the main gun and the rotaries were secondary along with the 40mm.
No, I have to disagree with both of you. I would argue that the Equalizer is the most important of the 3 guns mounted on the AC-130U.
Just compare the rate of fire of these weapons. That is the most crucial issue in my opinion.
25mm GAU-12/U Equalizer: 65 High Explosive Incendiary Rounds per Second
40 mm L/60 Bofors gun: 2 High Explosive Fragmentation Rounds per Second
105mm M102 Howitzer: 10 High Explosive Fragmentation Rounds
per MINUTE.Of course, the gunship can fire all three together at the same time, giving sort of a cumulative effect by combing the firepower of all 3 guns.
Tell me, if you were a Taliban running around on the ground, and an AC-130U was overhead, and it could only fire ONE of its guns at you, would you want it to be the 25mm GAU-12/U Equalizer ???
Here is another photo from another AC-130U Gunship, showing the 105m Howitzer in the foreground, and the 40mm L/60 Bofors in the background behind it.
