PLS-4 pipeline slim speaker

PLS series is slimmer than PL series…It’s just handrail size!


Pipeline speakers are revolutionary and literary line array speakers which create an ideal line sound source in a wide range by arraying multiple FPS transducer units with line array structure and properties.

By arraying transducers in line, “Pipeline speakers” have double line array structures in each speaker, which is impossible to achieve with conventional cone speakers. “Pipeline speakers” operate as ideal line array speakers in a wide range. “Pipeline speakers” are unique line array speakers fully demonstrating necessary properties as line array speakers.


We always hear from our customers, “No way! Is this speaker?”

High power in the compact body, best seller, it’s thin!!

Our Japanese customers use it as digital signage projects, Blackboard speaker, etc.
