The Perlisten S4s is built for those who refuse to compromise. Whether you’re completing a full S-Series theater or upgrading your surrounds to match world-class LCRs, the S4s delivers reference-level performance in a sleek, wall-friendly form factor. With the same proprietary driver architecture as its larger siblings, this speaker is a no-excuses solution for cinema lovers who expect full-range dynamics, precise imaging, and perfect timbre matching across every channel.

Key Features

• DPC Array: Beryllium tweeter with dual TPCD carbon fiber midrange domes for precision imaging and dynamic range

Perlisten Technology

At the heart of the S4s is the DPC (Directivity Pattern Control) Array, a precision-engineered driver system designed to deliver unmatched control of directivity and timbre consistency. The same array used across all S-Series speakers ensures a seamless surround experience, whether in two-channel or immersive multichannel setups.

Beryllium Tweeter

Covering the widest bandwidth in the S4s, the 28mm Beryllium dome tweeter offers unmatched speed and damping. It reproduces the highest frequencies with clarity and without the harsh breakup modes common in lesser materials. You get accuracy, transparency, and the ability to render even the most delicate high-frequency details.

TPCD Carbon Fiber Midranges

Flanking the tweeter are two 28mm TPCD domes. These ultra-lightweight diaphragms are made from Perlisten’s proprietary carbon fiber weave, engineered to suppress resonances while maintaining agility and bandwidth. This design allows for lower crossover points, reduced distortion, and lightning-fast transient response.

Waveguide Lens

The DPC Array is nested within a sculpted waveguide that controls early reflections and sound power. This ensures even dispersion across the listening area, improving vocal clarity, spatial imaging, and tonal balance regardless of seat location.

TPCD Carbon Fiber Bass

The S4s delivers real bass authority in a surprisingly shallow cabinet. Its 180mm Thin Ply Carbon Diaphragm woofer leverages the same woven carbon fiber tech found in Perlisten’s larger floorstanders. The result is fast, extended, and distortion-free low end—reaching down to 33Hz in-room.

TPCD is 30% lighter than standard carbon fiber, yet significantly stiffer. The unique layering of this material suppresses breakup modes and eliminates the resonant peaks that plague conventional woofers. It’s why the S4s can play deep, clean, and loud—while maintaining perfect cohesion with the mids and highs.

Built for Theater Obsession

The S4s may be shallow in depth, but it is deep in engineering. From its 50mm thick front baffle and dual internal braces to the 1/8-inch thermoacoustic damping throughout the cabinet, every element is designed for sonic integrity and mechanical silence. Details like recessed terminals and optional flush-mount kits make installation as elegant as the performance.
