X-Balanced Speaker UnitFront speakers feature an X-Balanced Speaker Unit. The unique rectangular shape of these speakers maximises the diaphragm. It reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.Separated Notch EdgeThe Separated Notch Edge on the X-Balanced Speaker Unit improves vertical amplitude symmetry, an essential for clear sound quality. It achieves this using strategically placed cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm.Deeper, richer bass soundA powerful wireless subwoofer with a large 160mm speaker unit delivers a deeper, richer bass sound.
