Meridian music surround modes are not just used for center fill like the tons of other ones out there. Besides the energy preservation characteristics of Trifield, it also digs into many theories from Ambisonic wavefront reproduction in its processing of the 2ch music source, allowing the 2/3 frontal channel to convert the dreaded pan-potted amplitude panning (in which the vast majority of music are recorded) into a sound that is true to how we really localize sounds.
