Cabasse Bora

The key to success comes from the subtle cocktail of experience and innovation. The co-axial technology by Cabasse is a major innovation in the loudspeaker world because its principle is the closest proposal to the theoretical ideal. It results from the 60 years experience Cabasse has in driver developments and the new version of the BC13 benefits from 20 years expertise in this type of midrange-tweeter.

BC-13 COAXIAL MIDRANGE TWEETER

Developed from the TC23, the three-way co-axial driver fitted to the top of the range speakers, including the flagship “La Sphère”, this new version of the BC13 has been optimized for even better performance when used as a two-way unit. The bandwidth is larger and the efficiency and the power handling are improved thanks to the use of new magnets offering a 30% increase in the force factor. The spatial coherency of this driver not only guarantees a faithful reproduction of timbres with no artificial coloration or lassitude in long listening, but provides a soundstage with unrivaled realism and depth.

DUOCELL CONE WOOFERS

The 21 cm (8.5”) woofer of Bora is fitted with a DUOCELL cone, which is based on Rohacell® foam. The first DUOCELL membranes were designed by Cabasse in the 1980s and since that time they been manufactured by robots in a Cabasse group company. The very light, but rigid and nicely damped membrane has an exponential profile and variable thickness, to obtain the most of long throw systems and powerful magnets. They bring the full precision and vivacity required for high fidelity, true to live, sound.

CROSS-OVERS WITH VARIABLE SLOPES

The Cabasse development protocol combines numerous measurements in an anechoic room, combining on-axis and 360° results. It guarantees a perfect control of the directivity index and the total radiated power of the system all along the frequency bandwidth to match the SCS principles. It is a key process, together with listening sessions in several rooms, in the development of the cross-over boards. The slopes can vary from 6 to 24 dB per octave for an optimal acoustical phasing, taking into account the influence of the external shape of the enclosure to optimise the qualities of the co-axial drive-units.

TECHNOLOGY AND ELEGANCE

The enclosure of Bora looks like their acoustical signature, pure and simple, free from any artificial appendix. Elegance outside, lots of technical solutions inside such as:
- Non-parallel side panels to remove standing waves – Variable thickness (up to 31mm) cabinet panels for rigidity and neutrality with an optimised volume for accurate loading of the woofers.
- Magnets to hold the front grill. When the speaker is being used without the grills, the front panel is free from pins or holes that can create diffraction effects. The magnets are located under the surface of the speaker, for a greater purity of sound and aesthetics.
- The bass-reflex port is positioned at the bottom end of the enclosure and fires vertically. It therefore reduces the creation of standing waves and provides a very efficient and linear extension of the low-frequencies thanks to a 360° radiation close to the floor.
