Largely to make certain that the Speaker Trims are not set too high in positive numbers which usually implies that digital boost is being applied. I would rather have to turn my master volume up a couple clicks while protecting digital headroom in the processing.
Ideally, all Speaker Trim numbers should be negative, and hopefully be at that 75dB mark. Along with that, your Sub(s) should always have the lowest Trim setting of all your Speakers.
