La Sphère – An acoustic Masterpiece
A world reference, La Sphère is a pure work of art. This masterpiece boasts power and precision with its 55 cm woofer; purity in its 4-way integrated driver, a deep and stable soundstage due to soundwaves without diffraction, perfect phase linearity in a 60° cone and powerful amplifiers with customizable home settings.
History of the Sphère
In 2006, the Sphère was introduced to the world at CES 2006 in Las Vegas. Equipped with the only quadriaxial technology in the world, the Sphère consisted of a TC23 and a 55 cm driver with a frequency response of 20Hz – 25 kHz.
Its high processing power allows for better clarity, delighting audiophiles from around the world.
Its main objective was to captivate music lovers in their quest for perfection. The Sphère’s architecture was carefully designed to avoid any standing waves or diffraction effects with its dense and aluminium base.
Designed in collaboration with award-winning French architect Sylvain Dubuisson, this 1.4m aesthetic masterpiece aims to be technically perfect in order to reproduce the entire range of sound frequencies.
The 70cm spherical speaker, made from a sandwich of composite materials (and originally designed for the European space programme), is coupled with the die-cast aluminium helical support, which positions the centre of the speaker at a perfect listening height.
Dedicated 4-Channel Stereo Amplifiers & Processor
The Sphere is displayed and sold as a complete system. Customers receive a package that includes: Cabasse amplifiers with La Sphère’s dedicated 4-channel digital stereo processor, a high-resolution Cabasse Streamer as well as a very high-quality preamplifier.
Each delivery La Sphère is accompanied worldwide by a Cabasse acoustician, who carefully and meticulously adapts the digitized parametric filters to perfectly match the listening room.
Measured in an Anechoic Chamber
Cabasse’s protocol for measurements in the anechoic chamber takes into account the measurements in the axis and on 360° for a perfect control of the directivity and the total radiated power, in accordance with the SCS principles.
It allows filters adjustments to be made to adapt to many listening sessions in rooms with different acoustics. They have cut-off slopes varying from 6 to 24 dB per octave with a perfect consideration of the shape of the cabinet and a total respect of the intrinsic qualities of our coaxial loudspeakers.
