Considering that the humidifier doesn't distribute precisely the same temperature and humidity level to all areas of the board at once doesn't keep it from working quite well on average. Holding your hand on the soundboard directly above both bars, feel the difference in heat. Not in what the rod is producing in air currents, but the temperature of the wood. I haven't tried this, so I'd be interested to hear your impression of what you feel. If the hot spot above the rod is a problem, why don't we install the rods parallel to and centered directly under the beams, using the beam as a diffuser? I've been wrong before, but I suspect Don's right, and there isn't much difference in soundboard wood temperature directly above those two rods. So many things that we worry about aren't really a big deal in practice, and so many of the things we are utterly unconcerned with are too important to ignore. We may never know which is which, but we can keep turning over the rocks trying to find out what we can. Ron N
