DSP Beam Steering Array Church Column Speaker

The gradient beam DSP column speaker is designed through in-depth research on room acoustics and the propagation of sound waves in both vertical and horizontal directions. By incorporating advanced physical directional waveguides, it effectively suppresses unwanted side lobes and achieves precise directivity.

Horizontally, a combination of acoustic structure design and DSP processing forms three directional beams with different radiation angles, respectively covering the near, mid, and far fields. Each beam allows independent sound pressure adjustment, while near-field coverage can be flexibly fine-tuned through DSP to achieve horizontal directivity control—ensuring sound accurately projects toward the intended area.

Vertically, asymmetric radiation is achieved using advanced DSP algorithms with gradual delay processing of three beams, combined with a specially engineered acoustic structure. This generates a downward radiation angle with strong suppression of unwanted upward emissions, significantly reducing ceiling reflections and improving spatial sound uniformity. The result is enhanced direct sound coverage, improved clarity, and minimized blind spots—especially effective in reverberant environments.

Thanks to these innovations, the column speaker provides excellent speech intelligibility and anti-reverberation performance, making it ideal for spaces with long reverberation times. It is widely applied in large and medium-sized command centers, lecture halls, religious venues, airports, railway stations, lobbies, convention and exhibition centers, and museums.
