Canton Atelier InWall 5 C black

A center speaker designed for architectural integration: the InWall 5 C is built directly into the wall, leaving only a discreet, frameless fabric grille visible. Mounted horizontally, it fits under a wall‑mounted screen or in a media cabinet without cluttering the room. Canton has packed the essentials of its loudspeaker technologies into this compact format: aluminum‑titanium chassis, passive radiator, and dome tweeter with waveguide.

A horizontal format tailored for dialogue

The InWall 5 C is a 2‑way bass‑reflex center speaker. Its horizontal orientation and dimensions (520 × 170 mm without grille) naturally lend it to placement under a TV or projector screen. The 3,000 Hz crossover frequency places the transition between mid‑bass and treble in a range that favors accurate voice reproduction.

The wide dispersion of the AB tweeter ensures a homogeneous sound throughout the room even if the speaker is not perfectly centered with respect to the screen. This is a real advantage when installation constraints force you to offset it downward or to one side.

Dual ATB drivers and passive membrane

The core of the InWall 5 C is based on two 128 mm mid‑bass drivers with aluminum‑titanium cones (ATB technology). This composite material combines rigidity and lightness: the cone resists deformation during transients while keeping the moving mass low enough to react quickly to the signal. The two chassis work together and share the speaker’s internal volume.

A 128 mm passive membrane, also in aluminum‑titanium, completes the system. It is not connected to the amplifier but oscillates under the effect of internal acoustic pressure. This passive radiator extends the low‑frequency response (down to a claimed 40 Hz) without the need for a port, which limits chuffing noise and simplifies integration in a confined space.

Wave surround suspension

The mid‑bass drivers use Wave surround suspension, a technology Canton employs across all its ranges. This multi‑pleat surround (as opposed to conventional single‑roll surrounds) allows for greater cone excursion while maintaining precise guidance. The controlled travel reduces distortion at high output levels and improves the speaker’s power handling. Continuous power handling is 70 W, with 140 W peak.

An AB tweeter with integrated waveguide

The 25 mm aluminum‑dome tweeter handles the treble range. Its waveguide (Wave lens) shapes the driver’s directivity to widen the listening area. In practice, listeners seated off the central axis perceive a tonal balance close to what is measured on‑axis.

The frequency response extends up to 40,000 Hz. This extension beyond the limits of human hearing (around 20 kHz) brings no direct audible benefit but demonstrates the tweeter’s ability to reproduce high audible frequencies without compression or rising distortion.

In‑wall installation: clips and oversized grille

The InWall 5 C is mounted in a drywall (plasterboard) or masonry wall using integrated mounting clips. These claws tighten against the inner surface of the cut‑out and hold the speaker in place with no visible screws. Required mounting depth is 75 mm (81 mm with the grille).

The fabric grille measures 570 × 220 mm, about 50 mm larger than the speaker in each direction. This margin covers the edges of the wall cut‑out and any finishing imperfections. The result is a uniform surface that does not reveal the exact outline of the enclosure. The grille is magnetically attached and can be removed without tools to access the drivers or clean the fabric.
