The bends and the walls are all part of the concept of the harmonic construction. In this way thought the non-parallel walls we are able to eliminate the standing waves that could arise in the bass cabinet. After cutting the walls we further tune each of them on a specific frequency resonance and spread. This allows us to control or and tune the behavior of the bass cabinet. Rather than suppress and have a completely damp cabinet, the excess energy is “harmonically” spread across a broader spectrum of frequencies carefully chosen.
