Our Review


The Perlisten Audio S4i LCRS is an in-wall loudspeaker specifically designed for high-end audio applications. Its impressive THX Dominus certification as a surround speaker and THX Ultra certification as an LCR (Left, Center, Right) speaker sets it apart from many other options on the market. With a fully-enclosed aluminum cabinet and a slim 4-inch depth, the S4i LCRS combines exceptional sound performance with a sleek and discreet design. In this review, we will delve into the various aspects of this speaker, evaluating its design, audio performance, THX certifications, installation process, and additional considerations.

Design and Build Quality

The Perlisten Audio S4i LCRS features a fully-enclosed aluminum cabinet, which not only enhances its durability but also minimizes sound leakage. The slim 4-inch depth allows for easy installation in walls without compromising on performance. The build quality of the speaker is exceptional, with attention to detail evident in every aspect of its construction. The aluminum cabinet feels sturdy and well-crafted, ensuring that the speaker will withstand the test of time.

Audio Performance

When it comes to sound reproduction, the Perlisten Audio S4i LCRS truly shines. The three dome drivers for mids and highs incorporate beryllium and Textreme TPCD materials, resulting in exceptional clarity and accuracy. The beryllium material provides rigidity and lightness, allowing for precise sound reproduction with minimal distortion. The Textreme TPCD woofer, measuring 180mm, is made from Perlisten's proprietary HPF material, further enhancing the speaker's performance in the low-frequency range.

One of the standout features of the S4i LCRS is Perlisten's patent-pending Directivity Pattern Control (DPC) waveguide. This innovative technology ensures precise sound dispersion, creating a cohesive and immersive listening experience. The DPC waveguide not only enhances the accuracy of the soundstage but also minimizes unwanted reflections and diffractions, resulting in a cleaner and more detailed sound reproduction.

THX Certifications

The Perlisten Audio S4i LCRS boasts two prestigious certifications from THX: THX Dominus as a surround speaker and THX Ultra as an LCR speaker. These certifications ensure that the speaker meets stringent performance standards set by THX, guaranteeing an immersive and high-fidelity audio experience. The THX Dominus certification for surround sound ensures precise and accurate positioning of sound effects, enhancing the overall immersion in movies and games. The THX Ultra certification for LCR speakers ensures that the S4i LCRS delivers exceptional performance and tonal accuracy for dialogue and music.

Installation and Setup

As an in-wall loudspeaker, the Perlisten Audio S4i LCRS requires professional installation. The in-wall design allows for a clean and unobtrusive installation, seamlessly integrating the speaker into the room decor. However, it is important to note that the in-wall installation process may require cutting into walls and running speaker wires, making it more suitable for new construction or renovation projects. The discreet design of the S4i LCRS minimizes its impact on room aesthetics, allowing it to blend seamlessly into any environment.

Additional Considerations

While the Perlisten Audio S4i LCRS offers exceptional performance and build quality, there are a few additional considerations worth noting. Firstly, the availability of the speaker may be limited, and pricing may vary depending on authorized dealers. This may make it more challenging to find and purchase the S4i LCRS compared to mainstream in-wall speakers. Secondly, in larger rooms, additional subwoofers may be required to achieve optimal low-frequency performance. It is important to consider these factors when planning the installation of the S4i LCRS.

Another aspect that could be improved is the availability of specific technical specifications. While the overall performance of the speaker is outstanding, potential buyers may appreciate more detailed information regarding power handling, frequency response, and other technical specifications. This would provide a more comprehensive understanding of the speaker's capabilities and assist in making an informed decision.


The Perlisten Audio S4i LCRS is a high-end in-wall loudspeaker that delivers exceptional sound reproduction and build quality. With its THX Dominus and THX Ultra certifications, it meets stringent performance standards and ensures an immersive audio experience. The innovative Directivity Pattern Control (DPC) waveguide technology enhances sound dispersion, resulting in a clean and accurate soundstage. While the S4i LCRS requires professional installation and may have limited availability and higher pricing, it is an excellent choice for those seeking a discreet and high-performance in-wall speaker solution. Overall, the Perlisten Audio S4i LCRS offers a compelling option for home theater enthusiasts and audio aficionados alike.
