Heso
Keywords: Equipment
The heso is the pyramidal cavity carved in the underside of a floor goban.
According to YMI ([1]), the cavity at the bottom of a goban (heso?) has to do with the drying of the goban.
Some say that it also improves the sound quality.
axd IMO, I cannot imagine how such a relatively small cavity in such a big mass of wood can contribute significantly in the sound of a stone put on the goban. But I'm note sure.
