Perlisten S7i-LR

The Perlisten S7i-LR is an in-wall speaker that stands out for its advanced audio performance in a discreet format. Designed to deliver an immersive sound experience comparable to that of a cinema, it combines modern technologies with a refined design, meeting the expectations of discerning audio enthusiasts.

A Technological Marvel with THX Dominus Certification

The S7i-LR is distinguished by its THX Dominus certification, the highest accolade awarded by THX. This certification ensures exceptional performance in spaces up to 184 cubic meters, with a viewing distance of up to 6 meters. The S7i-LR is the world’s first in-wall speaker to achieve this prestigious certification, demonstrating its ability to faithfully reproduce the most demanding soundtracks with remarkable power and precision.

Revolutionary Acoustic Design

At the heart of the S7i-LR is Perlisten’s patented DPC-Array (Directivity Pattern Control) system. This unique configuration combines a 28 mm beryllium tweeter with two ultra-light 28 mm TPCD (Thin Ply Carbon Diaphragm) domes. This trio of drivers works in synergy to deliver controlled directivity and a linear frequency response, ensuring sound reproduction with exceptional clarity and precision.

Deep and Controlled Bass

To complete the sound spectrum, the S7i-LR is equipped with four 180 mm woofers that also utilize TPCD technology. These strategically positioned bass drivers around the DPC-Array ensure powerful and articulate low-frequency reproduction. The TPCD technology, which is 30% lighter than standard carbon fiber while being more rigid, enables fast transients and minimal distortion, even at high listening levels.

Discreet Yet High-Performance Integration

Despite its impressive performance, the S7i-LR integrates seamlessly into your interior. With a mounting depth of just 10 cm, this speaker can be easily installed in most standard walls. Its extruded aluminum enclosure, featuring a bitumen damping layer, ensures consistent acoustic performance while minimizing sound transmission to adjacent rooms.

Unmatched Versatility

The S7i-LR is designed to adapt to various home theater configurations. It can be used as a left or right front speaker, or even as a center speaker behind an acoustically transparent screen. Its high sensitivity of 91.9 dB and ability to handle up to 600 W RMS make it an ideal partner for a wide range of amplifiers, ensuring optimal performance in any situation.

A Consistent Sound Signature

One of the key strengths of the S7i-LR is its ability to deliver a perfectly consistent sound signature with other models in Perlisten’s S series. This tonal uniformity allows for the creation of a perfectly balanced home theater system, where each speaker works in harmony to create an immersive and realistic soundstage.
