Overview
Traditional column speaker systems face an inherent limitation in sound beam formation: creating the main beam inevitably produces side beams. These side beams introduce acoustic interference, leading to comb filtering, uneven sound coverage, and increased risk of acoustic feedback (howling). Moreover, they reduce the efficiency of the main beam, causing the column’s surface wave to prematurely transform into a spherical wave, which sharply shortens projection distance. The unwanted energy radiated by side beams also generates multiple reflections from ceilings, floors, and walls, further reducing speech clarity.
To address this, many international manufacturers attempt to suppress side beams using physical modifications, driver customization, or DSP-based elimination. However, these methods vary in effectiveness and cannot completely resolve the issue.
MBS (Multi-Beam Synthesis) technology takes a fundamentally different approach. Based on acoustic theory, it employs specially designed waveguides and precision driver processing to synthesize side beams—once considered redundant and harmful—into the main beam. This eliminates the negative impact of side beams while strengthening the main beam’s energy and efficiency, resulting in a clearer, more uniform sound field and significantly extended radiation distance.
