In heritage and renovation environments, every millimetre matters. Wall structures cannot be deeply modified, and visible technology is often not acceptable.

Instead of working against the architecture, cerasonar works within it—using ultra-shallow integration methods that preserve original structures while enabling modern audio performance.

The result is sound without visual impact, even in the most restricted installation spaces.

Where traditional loudspeakers fail due to depth limitations, Cerasonar provides a different approach: sound elements that become part of the surface itself.

This allows audio coverage in areas where conventional installations would normally be excluded—without changing the architectural character of the room.

Typical heritage retrofits avoid direct installation into masonry or historical substrates. Instead, a lightweight dry-construction layer is used:

A slim batten structure is applied to the existing wall, followed by a gypsum board finish. In selected zones, the acoustic system replaces sections of the surface layer - fully integrated, fully invisible after finishing.

No structural intervention. No visible hardware. No compromise on design integrity.

Cerasonar is not about adding technology to architecture. It is about preserving the visual language of a space while upgrading its acoustic potential.

For heritage renovation projects, this means modern audio performance—without altering what makes the building unique.

The cerasonar 4062 architect is designed specifically for these demanding renovation scenarios.

With a total installation depth of only 30 mm, it fits into constructions where every millimetre counts. Once finished, it becomes completely invisible—leaving only the architecture visible, not the technology behind it.

For projects requiring extended low-frequency support, the system can be expanded with the cerasonar architect sub.

Combined with the cs-500dsp4 amplifier, the system delivers precise tuning and controlled dynamics tailored to architectural spaces—ensuring clarity, even in challenging acoustic environments.
