Orfeo

2 1/2 -way loudspeaker system

ORFÉO is a somewhat smaller, more room friendly, and less costly version of the monumental CONCORDE Signature. It inherits the spirit and unusual technical and musical qualities of its larger sibling and uses some of its components.

It is a two and a half-way system. It is lively, very fast, and provides gorgeous reproduction of musical timbres. Deep bass has great energy and power. Thanks to its extraordinary double ribbon tweeter housed in a solid wood head and to the carbon/kevlar/graphite compound of the cones of its splendid woofers, the ORFÉO’s timbres have extreme delicacy and great naturalness, with no projection effect at loud levels.
Thanks to the application of our research and technical study of the damping optimization of cabinet panels and techniques for machining them, we have achieved an ideal impulse response.
No vibration is generated by the cabinet, resulting in a clean, very fast sound with striking transparency and naturalness.
The ORFÉO is endowed with high sensitivity and, thanks to the geometry of its unbaffled tweeter, has very low directivity. It is very easy to drive, though like the CONCORDE Signature, it will give its best when driven by powerful amplifiers of high current capability. The ORFÉO is perfectly at ease with all the styles of music and is a welcome addition to the Reynaud line of speakers.

Electroacoustic performances

General design

Tuned triangular transmission line for the woofer. Tweeter is unbaffled. Adjustable spikes are provided, as well.

Drivers

Built by a manufacturer accustomed to producing professional speaker units with very low tolerances, they are designed to have exactly the same sensitivity. Thus no resistor is used in the crossover.
The woofer’s speaker’s cones are made with carbon/kevlar/graphite compound. Because their frequency response is very flat and without phase errors the crossover is as simple as possible.The ribbon tweeter is a handmade masterpiece housed in a solid wood head designed to produce a very regular polar diagram.

Cantabile signature

Few loudspeakers, nowadays, can display such impressive technical performances and such a manufacturing quality, normally reserved for much more expensive systems.

The meticulous optimization of the acoustic loading system; its geometric, electrical and mechanical parameters; the quality of all its constitutive elements and particulary of the hand-built loudspeakers: all contribute to produce remarkable results in term of musicality, airiness and natural.
Its unbaffled tweeter is capable of a very high energy at several meters in and off axis.
The optimized dynamic phasing of the two transducers ensures ideal time group propagation, the fundamental and the harmonics of the musical signal reconstituting themselves in perfect time concordance. Exactness of timbres is thus perfectly respected.
Comfortable with rock music as well as chamber music, the Cantabile demonstrates plainly that a perfectly designed loudspeaker is, by essence, versatile.

Emeraude

The Fruit of meticulous work and of 40 years of experimenting, measuring, and listening, this floorstanding loudspeaker integrates numerous innovations in design and technology.
Its two driver units and the architecture of its loading system benefit from our most recent researches.

The 6.5” woofer uses a sophisticated cone made of long carbon and kevlar fibers whose characteristics of steepness and internal damping are exceptional.

It is activated by a double magnet system with ventilated core. This technique avoids the increase of air viscosity enclosed in the air-gap of the magnet system at high levels and insures a perfect cooling of the moving coil wound[ed] on both sides of a 38 mm kapton high temperature support. This sophisticated technique avoids all resonance in the support and allows perfect cooling of the two layers of the deoxygenated pure copper moving coil.

The traditional dust cap is replaced with a solid phase plug which eradicates the turbulences generated at the center of the cone, optimizing frequency and transient responses.

The tweeter utilizes a very short moving coil which moves within the air-gap of a powerful neodymium magnet system. It is fixed between two hemispherical rings built of a very light soaked fabric that constitutes the cone. The symmetry of displacements of this moving coil allows it to act as a perfect piston (no swing phenomena of the dome as with traditional dome tweeters). Phase anomalies are also avoided. Its frequency response is perfectly flat, its resonance frequency is very low, and its off-axis response is excellent.

The loading system uses a triangular transmission line that allows a quick and deep bass response without coloration or distortion and a very fast establishment of wave trains. Machined under presses, the cabinetwork generates no resonances or vibration, resulting in a very clean and fast sound with striking transparency and naturalness.

Though its high sensitivity and benign impedance make the Emeruade very easy to drive, we recommend high level electronics to enable this speaker to achieve all that it is capable of.

Offrande supreme

Very soon after I saw the first outlines of the technical study of the original Offrande and then saw the results of the first tests, it was clear to me what the potential for the speaker could be. From that point, it became for me a continuous source of passion, astonishment, and joy.

What has struck me most forcibly about our new Offrande Supreme is its increased ability to capture both the intimacy of a musical performance and the integrity and wholeness of musical expression: its recovery of a performance is sensitive both to details of timbre and the fullness of instrumental sound. The key to this rare achievement is the Supreme’s remarkable ability to enable each individual instrument to find its own space within which it opens out freely. As a result, the Offrande Supreme has an extraordinary capacity to create a focused and strong musical bond between the music and the listener.

Since its conception in 1994, I have worked ceaselessly to enable the Offrande to evolve, attempting in each new iteration of the speaker to get closer to the musicians and the music. Today’s Supreme testifies to the constancy of my search for the best possible result. The smallest details of the speaker’s architecture and of its components have been meticulously optimized, so that nothing under our control can block its performance and its natural breathing.

The Offrande Supreme is designed for those who no longer find the spectacle of ‘high fidelity’ an attraction. More than ever this speaker makes it possible to understand without effort the expression and artistic intentions of musicians.

Højtalerkabel

First designed for aerospace applications, where performances must be outstanding, this cable is capable of conducting hyper-frequencies. Its group delay characteristics make it a state-of-the art cable when used in audio.
Its size may seem smallish to some, but was specially calculated for audio applications. We claim this is one of the best existing cable to this day. Its extremely tight manufacturing tolerance, the utmost quality of its components and its anti-oxydation treating will make it a lasting choice.
Comparison with the best copper conductors reveals a greater subjective linearity, a deeper low-end and an extremely natural treble. Its winding geometry and its ultra-low resistance will allow you to use different lengths of cable for your stereo channels without no sonic degradation.

About our speaker cables and interconnects

Why copper / silver ?

Metal is made of cristals linked together by a more or less conducting oxide called the dielectric. The resistivity of copper and the resistivity of silver are not highly different and should not, in theory, generate any significant change in quality.
It is true, though, that silver oxide is a better electrical conductor than copper. On the other hand, the influence of the dielectric is mainly significant in high-frequencies. It is now known that, the higher the frequency, the more the electrons will travel on the conductor’s surface.
We have consequently chosen a copper strand coated with silver. Both metals were specially treated (LCOFC and anti-oxidation). This technology allows remarkable sound, and reasonnable pricing.
To increase the silver conducting surface, and reduce capacitance problems, we have adopted a winding geometry of nineteen 0,30 strands. Our cable is perfectly reliable in a wide range of temperature, due to its molecular stability.

Why Teflon ?

Electrons travelling in a wire generate resonances (who hasn’t heard high-voltage wires «sing»?). These resonances are transmitted to the periphery of the conductor, where they will disrupt the transmission of high-frequencies.
Teflon is able to absord important vibration, even when used in a thin layer. It also «glues» to the conductor in a much more effective way than commonly used PVC, preventing distortion to travel at the junction of the insulation.
To check this, try to bare a cable coated with both materials! Teflon will give you a very hard time… Many manufacturers prefers to use PVC, though, because Teflon is a costly insulator.

Why Kapton ?

This material is a perfect insulator, able to dissipate without deformating very high temperatures (it is also used for moving coil supports in some speakers). Associated with an helical shielding, it also protects the signal travelling in the cable from outside magnetic radiations.

Why choosing 1,77 mm2 section ?

In high-fidelity and more generally in low-frequency, only low currents are transported, so a large section is totally unnecessary (20 volts under 8 ohms represent a 50 W power). The line resistance of the cable is the only data that matters, and depends directly upon the metals’purity. Since our metals, both copper and silver, are free from oxygen at 99, 5 %, the resistance of our cable is 8 ohms/kilometer only.
Thus, when using 10 meters of cable, the damping factor of the amplifier will always be above 33 for an impedance of 4 ohms, which is optimal.
How can you verify what we are asserting?
When soldering a common copper cable, caloric dissipation (hence, conduction) is relatively low. You can hold the cable near the melting point without burning yourself for some time. When repeating the same experience with our cable, heat becomes immediately unbearable, forcing you to use pliers to hold the cable.
