COLUMN SPEAKER

LSMActive (DSP) Column Speaker Series

LA Series

CX Constant-Impedance / Constant-Voltage Series

In recent years, column speakers, due to their slim and compact design, have been able to seamlessly integrate with the architectural environment, creating beautiful and comfortable listening spaces. Moreover, due to the characteristics of line sources, column speakers provide a more uniform soundfield coverage, wider horizontal directivity, and narrower vertical directivity compared to traditional point-source loudspeakers. Their excellent speech intelligibility and high sound reinforcement gain make them more suitable for applications in specific settings such as conference rooms and churches.

Currently, most column speakers in China are passive, with complex configurations. They require the use of associated devices such as mixing consoles, processors, and power amplifiers, as well as professional sound engineers for meticulous system tuning, making them very inconvenient to use.

The newly developed series of column speakers from Soundking has been equipped with professional digital audio processors, power amplifiers, and other devices. The performance parameters have been accurately adjusted according to the actual application scenarios. Users only need to connect the wires simply to use it normally, which greatly improves the installation and debugging efficiency of the sound system engineering contractor. It also makes the operation simpler and maintenance more convenient for the end user.
