This high-end passive loudspeaker brilliantly perpetuates the tradition dear to JMR of offering, in a compact format, an extremely musical system with acoustic performances worthy of a column loudspeaker.


The very long research and development work carried out for VOCEGRANDE has provided us with a set of innovative and particularly effective technical solutions, so it was logical that the flagship model of our range should also benefit from them.
This is how ORFÉOGRANDE was born, it is positioned above the current ORFÉOJUBILE in our range without replacing it.
Its silhouette, a visual signature of JMR models for years, is now highlighted by its two-tone finish that lightens and draws its curves with great elegance. The use of noble materials such as aluminum accentuates its sculptural aspect and it is a remarkable object in a contemporary or classic interior.

The sobriety of its design is an assumed choice, it allows to create simple and beautiful objects at the same time, anchored in their time, which will keep for a very long time a valorizing aspect with cleverly chosen proportions. Thus ORFÉOGRANDE will cross the times and the fashions without aging.


Taking over the work on the basis of an existing model as powerful as ORFÉOJUBILE is not an easy task.
All its infrastructure has been completely revisited, its cabinetry, its filtering, its speakers have been improved. VOCEGRANDE, with its extreme delicacy and its unique finesse of restitution, has significantly raised our standards. It was necessary to find in ORFÉOGRANDE all these qualities by adding the force and the energy of a column loudspeaker, while respecting its character and its personality so attaching.
It will have taken months and months for the research in laboratory and especially in listening, to lead to the expected result. This is why ORFÉOGRANDE is now the most successful passive loudspeaker ever made by JMR in the 55 years of its existence.


Brighter, quieter, more delicate and at the same time stronger than ever, ORFÉOGRANDE concentrates all the JMR know-how. It synthesizes the essence of the sound philosophy of JMR products, and once again, it pushes the performance limits of a loudspeaker of this size.
The sound image is truly spectacular, extending naturally and consistently beyond the system in width, height and depth and offering a scrupulous respect for the sound spaces of each recording.
The timbres are of extreme refinement and accuracy, without false light or coloration.

She plays complex music with an utterly insolent ease and never seems to struggle to reproduce the dynamics. Whether it is extreme on large orchestral formations, or subtle and perfectly nuanced on small formations or voices. The latter are carnal, but also perfectly articulated with an almost palpable presence. The diction, the articulation of each word, the breaths, the diphthongs, all that seems perfectly natural and integrated, never artificially put forward, that allows a perfect comprehension of the texts and better still of the intention and the meaning of an interpretation.

The music is expressed without constraint, with force and authority, but in a perfectly relaxed way, without any phenomenon of projection or hardness. Its precision allows an excellent readability of the phrasing and the intention of the musicians and yet one never has the feeling of deconstructing or overplaying the details. The sound message is full, fluid in the extreme, rich on all the audible spectrum and of constant density, that gets during the listening a feeling of permanent well-being that facilitates the musical emotion.

Its middle register is both rich and transparent, it depicts in a very natural way all the complex sonorities with a scrupulous respect of the harmonic gradation, essential parameter to fully identify each type of instrument. The harmonic friction of stringed instruments, the extreme complexity of the timbres of a piano, the resonance of a guitar note, everything seems more ample. The end notes last longer with a natural and very regular decay and never seem to be truncated. The superposition of the different timbres which form an expressive picture with very varied colors, provide a real auditory jubilation.

Thanks to the adoption of the polymer decoupling system of its base, the lower part of the spectrum from the low midrange to the extreme bass is sensational. Perfectly articulated and very dense, it expresses itself with an enthusiastic dynamism, giving a very frank and well controlled sensation of impact. He never overplays, yet he knows how to make himself particularly impressive when the music demands it. This decoupling principle allows the last octaves not to resonate with the floor material, which translates into a bass that is naturally positioned within the sound image and never gives the impression of crawling before it. Cleared of any parasitic vibration, it underlines, when necessary, the feeling of presence and gives the musical message a very realistic dimension and proportions. A kick drum, an organ pedal, a synthesizer pad or any other percussion instrument reaching the deepest part of the spectrum is then reproduced in a full and complete way to the extreme low end. Never does the message seem bloated or confused, on the contrary, one finds oneself detailing elements that are usually melted in the fog of these frequencies so difficult to reproduce with acuity.

ORFÉOGRANDE plays with all difficulties with agility and serenity, all musical styles find the right tonal balance and are reproduced with a scrupulous respect of their specific sonorities.


  • Device limiting the phenomena of solidian transmission of the vibratory energy thanks to the use of materials of different density (MDF-Aluminium). A 3 mm thick aluminum sheet encloses three sides of the cabinet to better concentrate the energy towards the interior of the acoustic load.
  • Loading principle: Tuned triangular line in ¼ wave leading to a front vent located at the bottom of the cabinet. This proprietary loading principle allows us to use almost no sorbent that would slow down the air flow in the different cavities. Thus, the signal propagation speed 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.
  • Complete mechanical decoupling of the enclosure base, allowing the use of Teflon pads as interfaces with the floor (no decoupling spikes). The speaker is as if suspended. Thus, the vibratory energy is transformed into heat within the polymer and is hardly transmitted to the ground. The result is a perfectly controlled bass that integrates with the musical message in a much more natural way since it never vibrates the floor material. The other advantage is to preserve the middle part of the signal without the drying phenomena often observed when using rigid decoupling tips.



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. Contrary to a classic ribbon tweeter which pushes the 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 big gaps of level as on the very small nuances).


Medium/boomer 180 mm
Its cone is made of 7 layers of carbon fiber and PEEK (Polyetheretherketone). This cone receives a plasma treatment on its external surface (granular) which avoids the formation of surface standing waves. This cone combines great lightness with good rigidity, but above all excellent internal damping.
This cone is driven by a 37 mm coil on two 16 mm long layers on a ventilated fiberglass support.
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.
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.
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.


• The passive filter :
It has been completely redesigned with different connection frequencies and the best components currently available on the market.
As usual, I wanted to reduce the number of these components as much as possible in order to obtain a speaker easy to feed.
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 speakers working in tandem and in phase below 200 hz or the bass speaker is connected in 6db/octave. The top speaker is dedicated to the mid/bass and is connected at 2200 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.
The equalization resistors for the tweeter are of a very high quality, they are wound and have the particularity to be 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) the whole is then trapped in an inert resin. 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. A ground braid is then connected to the terminal block of the speaker on a fifth terminal which is then connected to the ground of the domestic electrical installation. This completely drains all electrostatic and electrical charge and cleans up the signal for a more relaxing and detailed listening experience.
As usual, all the filters are made by hand, without using a printed circuit. The components are soldered directly to each other using ROHS silver solder and are attached with a flexible adhesive to forex plates that further isolate the components from vibration.
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 a new cable reference that uses some elements of our HP1132 cable but in a slightly different configuration since it has a star structure. The silver-plated copper core has a large cross-section and is then surrounded by small cross-section strands, still in silver-plated copper.
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 loudspeakers is entrusted to ETI terminals (the same as those used on VOCE Grande) which have been extensively compared and selected for their exemplary musicality. They are made of silver-plated tellurium copper of very low thickness providing an extremely low internal resistance. They are fixed on a bituminous aluminium plate


ORFÉOGRANDE gives off a lot of energy, which is why it is best suited to rooms of 30 m² or more. This being said, if the listening were to be done in a smaller room, it would be necessary to take care to keep a very reasonable listening level so as not to overstress the room.
A distance of 80 cm around it is recommended, this distance must apply to the side walls and especially to the back.
The distance between the axes of the enclosures should be about 3 m and can be increased to 4 m or more.
Since the directionality of the system is very low, it is not necessary to make the speakers converge completely towards the listening point. However, an angle of 5 to 15° depending on the distance will allow you to benefit even more from the very rigorous phase of the system.
ORFÉOGRANDE does not have a decoupling tip due to the design of its base. If your floor is uneven, you may need to insert adhesive felt pads under the bases to ensure that the speaker is stable.
Connecting the fifth terminal (ground): to take advantage of the grounding of the passive crossover at the level of the equalization resistors, you must connect the fifth terminal (gold) to the ground of your electrical installation (do not connect it to the ground of an amp). For this purpose, an ordinary cable (electric cable for example) will be sufficient, as no signal is carried by this terminal.
