Perlisten S7i LR In-Wall Speaker

The Perlisten S7i-LR delivers the performance of the flagship S7t tower in a speaker that vanishes into your walls. It is the world's first THX Certified Dominus in-wall loudspeaker, which means reference-level cinema sound with nothing in the room to see. For a dedicated media room or home cinema where the look of the space matters as much as the sound, the S7i-LR brings a level of immersive, dynamic, detailed performance no in-wall speaker offered before.

Key Features of the Perlisten S7i-LR

• THX Certified Dominus: The first in-wall speaker in the world to reach THX's highest performance class, for reference sound in large, high-end home cinemas.
• Flagship DPC-Array: The same patent-pending DPC-Array as the S7t tower, with a 28mm beryllium tweeter and dual 28mm TeXtreme TPCD midrange domes for precise accuracy.
• Identical Timbre Matching: Carries the same voice as Perlisten's S-Series freestanding speakers, so it drops into a hybrid in-wall and cabinet system without changing the sound.
• Four TeXtreme TPCD Woofers: Four 180mm TeXtreme TPCD woofers deliver powerful, fast, articulate bass with full cinematic impact.
• Integrated Aluminum Enclosure: A shallow 4-inch mounting depth and a rigid, integral aluminum back-box keep performance consistent in 2x6 or deeper stud walls while minimizing sound leakage into adjacent rooms.
• Acoustic Suspension Design: The sealed 4-way design delivers tight, accurate bass for the precise demands of movie soundtracks.
• High SPL Capability: Reaches 119.7dB peak sound pressure levels with very low distortion.

Performance That Disappears

The S7i-LR brings flagship sound to a speaker you never see. By adapting the design of the S7t into a shallow, 4-inch deep enclosure, Perlisten built a speaker that performs at a world-class level while staying completely hidden. The integral aluminum back-box is central to that: it gives the drivers the same controlled acoustic environment in every installation, so the S7i-LR sounds the same regardless of wall construction and keeps sound from bleeding into other rooms.

The Heart of the Action

At the core of the S7i-LR is the DPC-Array, born from 18 months of acoustic simulation. It controls sound dispersion to create a large, focused, deeply immersive soundstage. Vocals lock in space with clarity, and subtle atmospheric detail is rendered with precision that places you in the middle of the action. Because this is the same driver array found in Perlisten's tower speakers, the transition between in-wall and freestanding channels is invisible.

Uncompromised Cinematic Power

To earn THX Dominus certification, a speaker must reproduce the immense dynamic swings of a modern film score at reference levels without distortion. The S7i-LR clears that bar with room to spare. Four TeXtreme TPCD woofers and the robust DPC-Array handle the most explosive cinematic moments with control and authority, delivering the full impact and emotion of the cinema from a speaker built into the wall.

Complete the Perlisten Architectural System

The S7i-LR is the flagship left/right speaker of Perlisten's S-Series in-wall line, voiced to match the rest of the architectural range so a fully hidden system shares one sound:

• Anchor the front stage with the S7i-C in-wall center channel, its matching center.
• Scale the system to the room with the S5i-LR and S5i-C, 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.
