Egea and Iroise, names of two seas that have, for 15 years, graced successful
three-way tower speakers fitted with Cabasse’s unique co-axial midrange-tweeters.
To be deserving of these names, the new Egea 3 and Iroise 3 models had to pass a series
of rigorous lab tests and listening room evaluation. They had to adhere to the absolute fidelity
of the Cabasse Spatially Coherent System principles and show their ability to express all the
nuances of music, presenting the listener with an emotionally stimulating experience of sound.
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.
Enjoy every day new sonic experiences with your Altura MC speakers. In the heights of the
captivating 3D soundstage inherent to our SCS technology, every musical expression is
faithfully reproduced. Instruments and voices are where they should be. Their size, dynamic
range and timbres are respected. Savour and share true sound emotions.
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
optimised 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 colouration or
lassitude in long listening, but provides a soundstage with
unrivaled realism and depth.
DUOCELL CONE WOOFERS
The 17 cm (7”) woofers of Egea 3 are an evolution of the
units initially designed for the BAHIA speaker. They are
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 enclosures of Egea 3 and Iroise 3 look 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.
- The spikes delivered with the Altura MC tower speakers
are discrete but efficient.
They allow a fine and
easy adjustment of the
speaker’s stability by
means of an allen key
once the chrome plated
caps are pulled out.
New 3rd generation of Egea and Iroise,
heritage
and innovation.
