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


Pipeline speakers are revolutionary and literary line array speakers which create 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.
