Familienunternehmen
Bei cerasonar sind das Streben nach authentischem Klang und die Liebe zum Detail eine Familienangelegenheit
Vor mehr als 40 Jahren begann Ulrich Ranke mit der Entwicklung spezieller Lautsprecher, die auch unter technisch und akustisch anspruchsvollen Bedingungen puren Hörgenuss ermöglichen. Heute ist cerasonar gemeinsam mit seinen Söhnen zu einem Familienunternehmen herangewachsen, das auf „Made in Germany“ setzt und Kunden in mehr als 31 Ländern auf 5 Kontinenten betreut. cerasonar bietet Ihnen die Freiheit, in jeder Situation erstklassigen Klang zu genießen – ohne Kabelsalat und Platzverlust. Die Lautsprecher sind vollständig in Wände oder Decken integriert und somit völlig unsichtbar. Als Teil der Haustechnik sind sie die optimale Ergänzung für jedes Smart-Home-Projekt.
SOUND IS ENGINEERED AS A SYSTEM
EVERY COMPONENT HAS A PURPOSE
Conventional architectural audio often relies on adaptation during installation.
Cerasonar follows a different principle: define the system before it is installed.
Each loudspeaker operates within a clearly engineered framework that considers enclosure behaviour, mounting conditions, and electronic control as a unified acoustic reference.
This approach reduces uncertainty, improves predictability, and ensures consistent performance across diverse architectural environments.
DSP WITH A DEFINED REFERENCE
DESIGNED, NOT GUESSED
Cerasonar DSP presets are developed under defined acoustic conditions and validated as part of the system design process.
Instead of compensating for unpredictable installations, the DSP defines the intended acoustic behaviour from the outset.
This creates a controlled and repeatable performance standard across projects - without requiring extensive project-specific correction.
CONTROLLED INSTALLATION CONDITIONS
CONSISTENCY THROUGH ENGINEERING
The acoustic performance of an architectural loudspeaker is strongly influenced by its installation environment.
To ensure consistency, cerasonar provides dedicated installation frames and backbox solutions for selected systems, establishing defined rear volume conditions and stable acoustic boundaries.
This transforms the loudspeaker from a variable installation element into a precisely controlled acoustic system component.
INVISIBLE SUBWOOFER SOLUTIONS
Achieving convincing low-frequency performance remains one of the greatest challenges in architectural audio.
Cerasonar addresses this challenge through a range of dedicated invisible and architectural subwoofer solutions designed to integrate seamlessly into demanding environments.
INVISIBLE SUBWOOFER SOLUTIONS
LOW FREQUENCIES WITHOUT VISUAL COMPROMISE
Whether the objective is discreet low-frequency reinforcement, vibration-controlled architectural integration, or high-output performance for dedicated entertainment spaces, the subwoofer platform forms an integral part of the overall system architecture.
The result is bass performance that complements the architecture rather than competing with it.
ARCHITECTURAL APPLICATIONS
DESIGNED FOR REAL ENVIRONMENTS
Cerasonar systems are developed for a wide range of architectural contexts, including luxury residences, hospitality environments, heritage buildings, retail spaces, cinemas, and outdoor architecture.
Each application presents unique acoustic and structural challenges, requiring systems that adapt without compromising design integrity.
MATERIAL AND ARCHITECTURE
SOUND WITHOUT VISUAL COMPROMISE
Architecture is defined by material, proportion, and light.
Cerasonar systems are designed to disappear into this context without diminishing acoustic performance.
Whether integrated into plastered surfaces, bespoke joinery, veneered panels, or architectural concrete, each solution preserves the visual language of the space while enabling full-range sound reproduction.
DESIGNED FOR PROFESSIONALS
CREATED FOR ARCHITECTS, DESIGNERS AND INTEGRATORS
Successful architectural audio requires collaboration between multiple disciplines.
Cerasonar systems are developed to support architects, interior designers, consultants, contractors, and system integrators throughout the design and implementation process.
By combining clearly defined system architecture with dedicated accessories, documented installation methodologies, and project-specific guidance, the platform simplifies specification and reduces uncertainty throughout the project lifecycle.

A LEGACY OF LOUDSPEAKER ENGINEERING
MORE THAN FIVE DECADES OF ACOUSTIC DEVELOPMENT
The origins of cerasonar lie in decades of loudspeaker development and acoustic engineering.
Founder Ulrich Ranke’s early work in high-performance transducer design, including contributions to advanced diaphragm technologies such as Hexacone, established a foundation rooted in precision engineering rather than conventional audio manufacturing.
This engineering mindset continues to define cerasonar today - focused on controlled acoustics, system reliability, and long-term performance.
THE CERASONAR PHILOSOPHY
WHEN SOUND BECOMES ARCHITECTURE
Cerasonar exists at the intersection of architecture and acoustics.
The objective is not to showcase technology, but to integrate sound so naturally into built environments that it becomes indistinguishable from the architecture itself.
This is not invisible audio as a feature.
It is engineered architectural sound as a discipline.
