I did put the 816/v6 in his rack. There was someone else there at the time doing calibration. I did not install the ADA. The serious calibration was done by an individual I know very well and knows his craft exceptionally well. (Not the lad there that evening.)

I have measured the QSC down to a 10Hz signal. Your misunderstanding of the specifications is understandable. The fact the published specifications are only from 20 to 20k doesn't mean those frequencies are a brick wall.

I also have no clue as to why you'd be concerned with a 3Hz signal. First, it would not be audible. Second, even if you did have a sub that could reproduce it, the amount of energy required to reproduce it would be staggering. The fact of the matter is there are way too many music records with sub 20Hz content ... all of it unintentional. Why? It couldn't be heard by the studio/mix engineers (below audibility) or below the ability of the equipment (subwoofers) to reproduce it. That's a problem! Where below 20Hz is intended, you want to reproduce it. Where it is not intended, you wanna kill it off.

Imagine what you could do if you could do all you imagine.
