Cabasse La Sphere System

La Sphere – A Masterpiece of French Acoustic Engineering

A Visionary French Design

Crafted in collaboration with award-winning French architect Sylvain Dubuisson, La Sphere is a 1.4m marvel of both form and function. Designed to achieve technical perfection, it flawlessly reproduces the full spectrum of sound frequencies, offering an immersive and unparalleled listening experience.

At its core, the 70cm spherical speaker—constructed from a composite material originally developed for the European space program—is seamlessly paired with a die-cast aluminum helical support. This ensures the optimal listening position by precisely aligning the speaker’s acoustic center at the perfect height.

Uncompromising Audio Performance

La Sphère is engineered to redefine high-fidelity sound reproduction. Its advanced 4-way coaxial driver design eliminates phase distortion and diffraction, maintaining absolute sonic purity. With an extensive frequency response from 20 Hz to 23,000 Hz, it delivers deep, room-filling bass, pristine midrange clarity, and sparkling highs.

Key audio features:
✔ Dedicated 4-way coaxial driver for seamless sound integration
✔ Customizable DSP & amplifier settings for optimal acoustic adaptation
✔ Precise time alignment & phase control for spatial coherence

Dedicated 4-Channel Amplification & Digital Processing

La Sphère can be sold as a complete system, featuring Cabasse amplifiers and a dedicated 4-channel digital stereo processor to ensure absolute control over sound reproduction. Each amplifier module is optimized to provide the necessary power and finesse for every frequency range, allowing for an effortless, distortion-free audio experience.

Personalized Setup by Cabasse Acousticians

Every La Sphère system is delivered with a Cabasse acoustician, who meticulously fine-tunes the system using digitized parametric filters. This ensures the speaker adapts flawlessly to the acoustics of the listening environment, providing a customized and optimized sound experience tailored to the client’s space.

Precision-Measured in an Anechoic Chamber

Each La Sphère undergoes rigorous testing in an anechoic chamber, ensuring precise directivity control and total radiated power optimization. This meticulous process guarantees an exceptionally accurate soundstage, whether in a private home, studio, or exhibition space.
