Enclosure volume of cube with Auratone approx dimensions is
260 cubic inch.
Enclosure volume of tetrahedron, 12in edge length calculated by the formula
V = (α cubed x square root of 2) : 12 =
200 cubic inch approx
More listening tests are done after initial failure of tetrahedron frequency response measurements
More time is now spent of listening to the cube. Perhaps a preference indication.
Both speakers are on linoleum 1m x 2m carpet on top of wooden floor.
Maria Magdalena - Sandra for example was applying on FM radio. Switching between the speakers revealed more midrange with balance in cube and more mid Hugh edge on tetrahedron.
