Perlisten S5i-LR

The Perlisten S5i-LR in-wall speaker represents a significant milestone in high-fidelity audio for wall-mounted installations. Designed to deliver precise and immersive sound quality, it combines advanced technologies with a design that seamlessly integrates into any interior.

Revolutionary Audio Technology Built Into Your Walls

The Perlisten S5i-LR incorporates remarkable technological innovations, making it a benchmark in its category. At the heart of this system lies Perlisten’s patented DPC (Directivity Pattern Control) array. This setup features a 28mm beryllium dome surrounded by two ultra-light 28mm TPCD (Textreme Prepreg Carbon Diaphragm) domes. This unique configuration enables precise control of sound directivity, ensuring faithful reproduction of vocals and delicate high frequencies.

To complement this acoustic setup, the S5i-LR is equipped with two 180mm woofers, also made of TPCD. This combination of drivers delivers an impressive frequency response of 52 Hz to 37 kHz (-10 dB), ensuring rich and detailed sound reproduction across the entire audible spectrum.

Discreet Integration for Maximum Sound Impact

Despite its exceptional acoustic performance, the S5i-LR stands out for its ability to blend harmoniously into your living space. With a mounting depth of just 101.7mm, this speaker can be easily installed in most standard walls. Its extruded aluminum rear enclosure not only ensures consistent performance but also minimizes sound leakage into adjacent rooms, a major advantage for home theater setups or multi-room audio systems.

The S5i-LR’s sleek design, featuring a white grille and black baffle, adapts to a variety of interior décors. This minimalist aesthetic allows the speaker to blend into the wall while delivering outstanding sound quality.

Certified Performance for Discerning Audiophiles

The S5i-LR is not just a technical marvel; it is also recognized by industry experts. Its THX Dominus certification, the highest level of THX certification, attests to its ability to deliver cinema-quality sound in spaces up to 184 m³. This certification ensures that the S5i-LR can faithfully reproduce the most demanding soundtracks, even at high volume levels, without perceptible distortion.

With a sensitivity of 91.9 dB (2.83V/1m) and the ability to handle up to 350W RMS, the S5i-LR offers impressive dynamics. It can achieve peak sound pressure levels of 117.3 dB while maintaining harmonic distortion below 3%, ensuring exceptional clarity even during the most intense passages.

Acoustic Versatility for Any Environment

The S5i-LR shines with its versatility. It can be used as a left, center, or right speaker in a home theater setup, or as a stereo pair for high-quality music listening. Its three-way suspended acoustic design ensures remarkable sound coherence, regardless of its placement.

With a nominal impedance of 4 Ω (minimum 3.1 ohms), the S5i-LR is compatible with a wide range of amplifiers. However, to fully exploit its capabilities, Perlisten recommends an amplification power between 100 and 350W RMS.

Precision Acoustic Engineering

The S5i-LR’s design is the result of meticulous engineering. The use of advanced materials, such as beryllium for the central tweeter and TPCD for the other drivers, reflects the attention to every detail. The DPC array, the result of 18 months of intensive simulations and prototyping, employs advanced acoustic modeling via Comsol to deliver unparalleled directivity control.

This scientific approach translates into remarkable linearity, with a frequency response of 80 Hz to 20 kHz (±1.5 dB), ensuring natural and balanced sound reproduction across the entire audible range.
