I don't mind loud, as long as it is clear. Usually the louder these speakers get turned up, the more distortion there is, which defeats the purpose of being able to understand what they are saying. I also understand why they are up so loud, in theory they want you to be able to hear when a car is running, but when there is an oildown or no cars running, the PA systems can be overbearing which is only exascerbated by the distortion (THD for you audiophiles). And when team Geico gets on the horn they shout into the mics rather than talk into them as the announcers do ... it gets even louder and more distorted. Surely there has to be a way to dynamically change the power output/volume to suit the situations on the track. We don't need it cranked to 11 when the sweeper is in the shutdown area.
I would also like to point out before someone else does, that I consider this nitpicking LOL. This would be way down the proverbial list of things I would change should I be given a magic wand.
