Since the beginning of its career, almost 15 years ago, the ORFEO model has always been an extremely prolific research laboratory in technical solutions for JMR. Always seeking to push the limits of what a system of its size can do, it has allowed us to reach a great sonic maturity and an ever greater harmonic richness. From one generation to the next, it has never ceased to surprise and delight us with its dynamic capabilities and its sound image, which is ever more ample and ever more precise.

Developed patiently and with great rigor, the ORFEO in this Jubilee version is the quintessence of JMR know-how.


Developed patiently and with great rigor, the ORFEO in this Jubilee version is the quintessence of JMR know-how.

Extremely linear and generating a signal of a constant density whatever the register, it distils with a real ease a subtle musicality, without caricature, and very nuanced. Equally at ease with small acoustic ensembles as with the telluric loads of a symphony orchestra, it gives the impression of serenity coming from a system without limits.

The ORFEOJUBILE is not an improvement of the Supreme V2 version but a complete new development around the same concept. A relatively compact 2.5 way loudspeaker with a very high level of timbre and energy.

All the technical elements have been revised: Load, speakers, filtering and even its aesthetics. We find the silhouette of this new Jubilee line with a large fillet on the rear horizontal edge of the cabinet. It is also slightly more voluminous to match the tuning of its new perfectly optimized acoustic load and tuned even lower. The harmonic richness that characterizes JMR products is perfectly respected, without exaggeration and without sacrificing the transparency and immediacy necessary for a good reading of the musical message. The interpretation of a work, even a very complex one, becomes surprisingly easy to understand and listening is effortless, quite natural. Technically very sophisticated it was as usual sharpened and validated by long hours of listening. This makes it possible, where measurement no longer shows anything, to optimize its performance even better, bearing in mind that a system, however elaborate it may be, must above all be a true vector of emotions.

Thanks to its very good efficiency and the exemplary linearity of its impedance curve, the ORFEOJUBILE is easy to feed. However, it requires very well made electronics with well dimensioned power supplies in order to take full advantage of its very nice vivacity and its impressive dynamic capacities. Although it has a very wide frequency response in the low end of the spectrum, the ORFEOJUBILE is easy to position, even in a relatively small room. The proportions of its geometry and its extremely meticulous finish make it a precious object that can be easily integrated into any interior, whether classic or contemporary.


The proprietary acoustic load at our realizations has been rethought and optimized in its profile, but still remains a triangular line tuned in ¼ wave leading to a front vent at the foot of the speaker.
This new version of our triangular line allows us to use almost no absorbent in the line itself. Only the dividing wall is covered by a small amount of thin acoustic foam and a ring of honeycomb foam acts as an acoustic diode on the back of the speaker cones. There are no sorbents to impede the flow of air through the load. Thus, the signal propagation speed in the line is much faster and the group propagation time of the system is greatly improved. In order to better control the vibratory phenomena, we have lined a large part of the internal surfaces of the cabinet with bitumen and viscoelastic compound positioned in an experimental manner at strategic points.

The tweeter is housed in a piece of solid wood that has been turned partially and is decoupled from the upper surface of the cabinet by means of a bitumen seal.
The whole cabinet rests on a base which is decoupled by a viscoelastic compound joint and placed on adjustable spikes with counter spikes.


AST type tweeter (aerostriction) :
It consists of a pleated diaphragm 25 mm wide by 60 mm high, whose silicone support is covered with a very thin film of extremely light avionics-type aluminum. This diaphragm is traversed by an aluminum greek and the whole is surrounded by two neodymium bars of very strong power. Its operating principle is the same as that of the Heil or AMT transformer, but it has the particularity of using a diaphragm that is perfectly devoid of its own resonance. Unlike AMTs using KAPTON for their diaphragm, this one is very smooth while being informative and fast. Unlike a conventional ribbon tweeter that pushes air in front of it, the aerostriction tweeter pinches the air between its folds and expels it with a very high velocity. The dynamics is thus much greater (on the large differences of level as on the very small nuances…).
It is not very fragile, has a very high power handling and a much lower distortion rate than the ribbon, especially at the end of the band, where its displacements are the most important. It can thus be used much lower in frequency than a ribbon while using a less steep filtering slope. Moreover, its impedance curve is perfectly straight and it does not have a marked resonance frequency. Finally, its horizontal directivity is extremely low. As it works as a dipole, it is essential to associate a small closed load behind it which must be tuned experimentally and which is damped by a specific extremely airy felt.



These new 180mm HPs were developed in collaboration with a German company that only works on OEM products. We had already collaborated on the CANTABILEJUBILE tweeter which, for me, is probably the best textile dome tweeter I have heard.
It took almost a year and a half of work on several prototypes to finalize the study of this extremely powerful HP.
Its cone is made of 7 layers of carbon fiber and PEEK (Polyetheretherketone). This structure is particularly long and complex to achieve, because each layer must be produced with a very precise drying time to allow the whole to be as homogeneous as possible. This cone receives a plasma treatment on its external surface (granular) which avoids the formation of standing waves. This cone combines great lightness with good rigidity, but above all excellent internal damping. The cone of a loudspeaker is a clever combination of rigidity and internal damping capacity to avoid the resonances specific to the material used. On this particular point, we have achieved particularly satisfactory results.
This cone is driven by a 37 mm coil on two layers of 16 mm long on a ventilated fiberglass support, this support receives a surface treatment in order to dampen its own resonance frequency as much as possible. A ring of plasma-treated material is placed on the field of the coil support, again to prevent the coil support material from manifesting itself acoustically.
The air gap has a pure copper ring to linearize the impedance of the loudspeaker at the end of the band and to reduce its distortion by improving the concentration of the magnetic flux around the coil.
Its speeder is airy and has a progressive profile to allow a movement with a constant return force whatever the amplitude of its movement.
This boomer has a double ferrite magnet of 100 mm with double control ring and has a very strong magnetic field.
The NBR rubber suspensions have an optimized profile in terms of their curvature in order to obtain a progressive splitting and to maximize the efficiency of the return according to the distance of displacement of the mobile equipment.
Its bowl is made of aluminum and clears the back of the cone.
Its core is drilled, but receives a damping treatment consisting of several disks of oriented microphonic felt.
A fabric dome impregnated with a specific treatment on its inner side covers the coil and is glued to the cone with a latex-based adhesive.
These loudspeakers are tensioned as usual, thanks to stainless steel threaded rods that come to push the breech of the speaker and are tensioned on the back wall of the cabinet. This principle brings the mechanical reference of the loudspeaker to the back of the cabinet and ensures a better distribution of mechanical stress on the front of the cabinet. It improves the transient operation of the HP by stabilizing its mechanical reference. This results in a midrange that is free of all distortions related to the micro-displacement of the speaker motor and a much faster and better damped impulse response.


It has been the subject of much attention and a very long period of optimization. During 6 months, I compared and tried different filter configurations, but also different types and brands of components in order to retain only the best. These components are extremely qualitative and therefore particularly expensive. These tests were carried out with the measurement of course, but also and especially with the listening in order to select those which, beyond what could show the work of laboratory, showed themselves the most powerful with the listening.
As usual, I wanted to reduce the number of these components as much as possible to obtain a speaker that is easy to power. No resonant circuit or plug circuit. Only the components necessary for the realization of the 6/12/12 dB/octave filtering are used.
This is a 2.5-way configuration, with the two bass-midrange drivers working in tandem and in phase below 400 Hz, where the bass driver is connected in 6 dB/octave. The top speaker is dedicated to the mid/bass and is connected at 3500 hz with the tweeter and is not filtered in the bass.
This filter consists of two separate cells, oriented and separated from each other to avoid intermodulation of components.
We use silver armature capacitors with HP1132 (silver/copper) cable termination. The winding orientation is marked and they are specific to our use (manufactured under specifications by a French company S.C.R).
The chokes are made of large pure copper strips, wound around a solid wood mandrel and encased in wax to prevent unwanted radiation and intermodulation. These chokes have the particularity to offer an extremely low distortion rate, a very low internal resistance and very high power handling capacities. This translates into a very full, articulate bass with great density, substance and dynamics. They are used both on the bass, but also for the connection of the medium with the tweeter.
They are oriented in relation to each other to avoid unwanted radiation.
The resistors for the equalization of the tweeter level are of very high quality. They are wound and have the particularity of being surrounded by a copper tube connected to the ground of the system (they have three wires, input, output and ground and must be oriented in the direction of signal flow). This copper tube acts as a shield (Faraday cage) and eliminates all electromagnetic disturbances around the component which are evacuated by the system ground, but also acts as an excellent heat sink. Thus, the distortion rate of this resistor is particularly low. At large level differences, conventional resistors tend to get very hot, which results in distortion. With these resistors, the treble is very transparent (evacuation of the micro discharges) and extremely dynamic with a sensation of astonishing naturalness, leaving room for all the micro information essential to a really musical listening. The harmonic gradation is much more logical and devoid of “slag”, the treble is matt, fine, without persistence or undesirable granulosity effect.
As usual, all filters are made by hand, without using a printed circuit board, the components are soldered directly to each other using ROHS silver solder and are fixed with a flexible glue on forex plates that further isolate the components from vibrations.
The two cells are arranged as far as possible from the magnetic radiation of the loudspeakers and are themselves acoustically shielded with compound and foam.
All the internal wiring is done with our HP1132 cable, which has a doubled section for the midrange and bass.
Chaque composant est mesuré et trié par paire avec une tolérance de 1%. Thus the crossover components have perfectly identical values on the pair of speakers
The connection of the speakers is entrusted to Mundorf terminals in pure copper of very high quality and selected for their exemplary musicality. They are fixed on a bituminous aluminum plate. The connection of the cables to the passive crossover is made without soldering by means of pure copper grommets, also of Mundorf origin.


Thanks to a very low directivity, it is not necessary to converge the two speakers to the ideal listening point, pinching them very slightly in order to make the most of the system’s phase.

The spacing will be determined experimentally. It is ideal theory around 3 m from axis to axis, but this distance can be reduced. To achieve a deep, well-built stereo image, make sure that the speakers are at least 80 cm away from the side and rear walls.

The best results in spectral balance and musicality were obtained by using our HP216B cable, the same one used for the internal connection of all system components.
