Perlisten S5i-LR In-Wall Speaker

The Perlisten S5i-LR in-wall speaker translates the dynamic, immersive performance of the acclaimed S5m monitor into an architectural format. Built for the listener who wants uncompromising sound without a speaker box in the room, the S5i-LR is a true high-performance loudspeaker with an integrated aluminum enclosure for consistent, predictable results in any wall. Certified for THX Dominus, it anchors a reference-level home cinema that is heard but not seen.

Key Features of the Perlisten S5i-LR

• THX Certified Dominus: One of the only in-wall speakers in the world to earn THX's highest certification for an LCR channel, for reference performance in large home cinemas.
• Proprietary DPC-Array: The heart of the speaker is the patent-pending DPC-Array, a central 28mm beryllium tweeter flanked by dual 28mm TeXtreme midrange domes for precise accuracy and dispersion control.
• Perfect Timbre Matching: Shares the same voice as the S5t, S5c, and S5m, so you can build hybrid systems that carry one consistent sonic signature across the room.
• Beryllium Tweeter: The 28mm beryllium dome delivers high-frequency detail and extension with clarity and no harshness.
• TeXtreme TPCD Woofers: Two 180mm TPCD (Thin Ply Carbon Diaphragm) woofers deliver fast, articulate bass with real low-end power.
• Integrated Aluminum Enclosure: A shallow 4-inch mounting depth and a rigid, integral aluminum back-box keep performance predictable and minimize sound leakage into adjacent rooms.
• Acoustic Suspension Design: The 3-way acoustic suspension delivers tight, accurate bass, ideal for music and movie soundtracks alike.

Architectural Audio, Perfected

The genius of the S5i-LR is its no-compromise design. Unlike many in-wall speakers that use the wall cavity as their enclosure, the S5i-LR has a custom-engineered, sealed aluminum back-box. This integral cabinet gives the drivers the same controlled acoustic environment in every installation, so the speaker performs to its full potential no matter what is behind the wall. It removes the guesswork, delivers the consistent, reference-quality sound Perlisten is known for, and keeps sound from bleeding into other rooms.

Installation is tool-light and secure. Rotating dog-leg clamps draw the speaker tight against the drywall once it is set into the cutout, holding it flat and flush with no visible fasteners on the baffle.

Clarity by Design

At the core of the S5i-LR is the DPC-Array, a directivity-control design that brings clarity and focus to the sound. By managing the speaker's dispersion, the DPC-Array sends more sound to your ears and less toward reflective surfaces like the floor and ceiling. The result is a clear, intelligible performance, especially with vocals and dialogue, and a wide, immersive soundstage with pinpoint imaging that lets the speakers disappear into the wall.

Phenomenal Dominus Power

Earning the THX Dominus seal is an extraordinary achievement, signifying that a speaker can reproduce the full dynamic range of movie soundtracks at professional cinema levels. The S5i-LR meets that challenge, delivering explosive transients and subtle ambient detail with equal composure. It reaches staggering sound pressure levels with very low distortion, so you feel the full emotional weight of a film, from the quietest whisper to the most thunderous explosion, from a source hidden behind a simple magnetic grille.

Complete the Perlisten Architectural System

The S5i-LR is the left/right anchor of Perlisten's S-Series in-wall line, voiced to match the rest of the architectural range so you can build a fully hidden, timbre-matched system that still hits THX Dominus levels:

• Anchor the front stage with the S5i-C in-wall center channel, voiced to match the S5i-LR.
• Step up to the flagship S7i-LR and S7i-C for the largest rooms, or use the multi-purpose S4i-LCRS for surround duties.
• Add height and overhead channels with the S3ic in-ceiling speaker.
• Prefer to mount on the wall rather than in it? The Perlisten X-Series on-wall speakers share the same design language.
