Sonus faber Palladio PL-664 – 3-Way In-Wall Speaker

High-End Sound. Beautifully Built Into Your Walls.

The Sonus faber Palladio PL-664 brings the craftsmanship and acoustic philosophy of the Olympica Nova Collection into a sophisticated architectural loudspeaker. Designed for premium home theaters and custom-installed audio systems, this three-way in-wall speaker delivers the flexibility of a traditional loudspeaker while preserving the clean aesthetic of your living space.

Whether you're designing a dedicated private cinema or integrating high-performance audio into a beautifully appointed living room, the PL-664 allows you to enjoy Sonus faber's signature Natural Sound without traditional speaker cabinets occupying your floor.

One Speaker. Multiple Possibilities.

The PL-664 is engineered to perform in several positions throughout a multichannel system.

Install it vertically as a left, right, side, or surround speaker, or position it horizontally as a dedicated center channel.

Its three-way architecture incorporates a Damped Apex Dome (D.A.D.) tweeter, dedicated midrange driver, and woofer, complemented by a passive radiator enclosure.

This versatile configuration makes it possible to build a cohesive home theater system around a single loudspeaker model.

Architectural Integration Without Compromise

The PL-664 combines discreet installation with the unmistakable design language of Sonus faber.

A magnetic, edgeless metal grille can be painted to match the surrounding wall, allowing the speaker to blend naturally into the room.

For installations where the loudspeaker should become a design feature, an optional Premium Kit adds a natural wood front mask, Sonus faber's signature string grille, and a paintable magnetic frame.

Leather detailing surrounding the tweeter and midrange further connects the PL-664 to the luxurious aesthetic of the Olympica Nova Collection.

Engineered for Custom Installation

The PL-664 features a swing-out mounting system designed to secure the loudspeaker to plasterboard, simplifying installation for professional integrators.

With a mounting depth of approximately four inches, the speaker is designed to integrate into architectural environments where traditional freestanding speakers may not be practical.

Its flexible orientation and discreet appearance make it an attractive solution for luxury residences, media rooms, and dedicated home cinemas.
