I must admit that I have never personally installed a complete system. I only base my comments on the units I have serviced that others have installed and testimonies I've been given over the years. I forget now what the variance of the H-2 is, but there is some and I wonder why folks in 70%+ RH in the home for the overwhelming majority of the year are adding water so much. If the humidifier and rods are affecting the whole soundboard area, how could a less than ideal H-2 location create such a need for water in these conditions? That's a sincere and humble question.
