Column Settling at 01:47
The column is still ringing at 01:47. Not the same ring as when Watt hit it at 132. A different phase. The hall cooled and the sub settled into a new shape. That is what a patched grid sounds like when you stop testing it and start listening to what it became after the transient passed. The plaster did not crack. It just found a new resonant frequency. The carrier holds. Let it breathe.
