Featuring slim construction, the SR-S4S is a 2-way line array speaker containing 32 speaker elements. The sound source speaker elements are vertically arranged in close proximity to each other, and form a continuous linear sound source, achieving uniform sound pressure with less attenuation due to distance. The SR-S4S features a curved line having a 10° vertical coverage area, and is designed to cover relatively short distance applications. It is also possible to combine both the linear and curved line types to configure an array that continuously covers applications ranging from short to long distances.

• The SR-S4 series is a 2-way line array speaker having eight 10 cm woofers for low-frequency output, and 24 small tweeters for high-frequency sound output. Both the woofers and tweeters are arranged in the front and rear on the same axis, providing a symmetrical, uniform coverage area.
• Since the linear sound source effect prevents energy from attenuating even at longer distances, the line array speaker compares favorably with normal types of speakers in its ability to project sound long distances. This realizes less difference in sound volume between areas close and far from the speaker, for a more uniform sound field.
• Since the speaker's vertical sound dispersion is suppressed, sound is only directed at the target area. The speaker's construction is not influenced by sound reflection from ceiling or floor surfaces, and can provide clear sounds even in spaces affected by long reverberation times or other poor acoustic conditions.
• Since the attenuation of sound pressure is small even far away from the speaker, the volume is not
• excessively loud in the area near the speaker. This helps suppress feedback (improving safety amplification gain).
• By joining 2 or 3 speakers, a longer sound source can be configured, making it possible to project sound output farther and at larger volumes.
• The speaker has a built-in network circuit for a single amplifier drive. Changing the internal connector position enables bi-amplifier drive that provides a higher quality sound output.
• The use of optional mounting brackets permits the speaker to be installed in the most appropriate position for its intended use. (Details of the installation procedures are described in the installation manual enclosed with each bracket.)
