New to Adventures – JM Reynaud Loudspeakers
21 September 2023
Founded in 1967, JM Reynaud Loudspeakers was borne from one man’s passion for high quality music transcription – Jean-Marie Reynaud, a trained pianist and music fanatic. Jean-Marie’s raison d’être, his driving force, is his desire to re-create the ultimate – live music. And he can be found today doing just that in JMR’s labs and listening rooms.
JMR produces a range of superb stereo loudspeakers – bookshelf, floorstanding and on-wall, which are revered not just in it’s home country of France but worldwide. Refined, versatile and dynamic, JMR speakers are extremely easy to drive (typically c.91 dB sensitivity) and so easily produce wonderfully detailed audio from lower-powered amps, integrated and one-box systems.
We’ve found they work exceptionally well with Linn Majik and Selekt DSMs, as well as Rega and Naim integrated amps and Uniti range.
We start our JMR journey with two floorstanders – LUNNA (£1900) and CANTABILE JUBILÉ (£4500)
Both models are available for listening now, just get in touch to arrange: hello@adventuresinhifi.com or 01244 345576.
LUNNA
LUNNA is lively and dynamic, equally at ease with all musical genres and with a surprisingly small footprint (< 31 cm x 19cm), unimposing, yet will easily fill most listening and living spaces. It’s simple design and finish options – Satin Black or Cherry – make it easy to integrate in any interior.
Initial listening results from LUNNA are impressive: its homogeneity, frequency response, impulse response and extremely neat phase curve means it reaches a performance level well beyond its price-point.
Lunna is the perfect partner for the likes of Linn Majik DSM, MOON Ace, Rega Elex/Elicit, Naim Uniti, Nait XS/Nait 50.

CANTABILE JUBILÉ
CANTABILE JUBILÉ launched in 2017 to celebrate JMR’s Golden Jubilee year, is a significant milestone, setting a new standard for musicality. A complete re-design of the original Cantabile, Jubilé more than any other epitomises Jean-Marie’s quest for perfection.
Fluidity, nuance, refinement, spontaneity and agility characterise CANTABILE Jubilé, thanks to JMR’s development work in acoustics and electronics. A completely revised crossover, new silk dome tweeter, bigger and re-positioned nose cone results in ultra-precise dynamic phasing. The very low resonance frequency and distortion rate of this tweeter allows the connection frequency with the bass-midrange speaker to be lowered to just 3 kHz. Filtering has been done with as few components as possible, making the CANTABILE Jubilé much more responsive and even easier to power.
These are available in Satin Black, Pearl White, Charcoal Grey and Wood finishes and although compact for a floorstanding speaker, offers a particularly full, wide and deep sound image. CANTABILE’s mid-range has always been admired by discerning music lovers. In this Jubilé version, the CANTABILE retains that, but with even more fluidity and airiness. The rich and varied timbres are truly natural, it delivers fast yet perfectly controlled bass and above all, a remarkable homogeneity for a speaker of its size.
As agile and alert on a string quartet as on contemporary music, the CANTABILE Jubilee offers its listener hours of listening without weariness or fatigue. Matching electronics should be nigh quality, but not necessarily powerful – Linn Selekt DSM, Rega Aethos are perfect examples.

Lunna full specification
LOADING PRINCIPLE:
Tuned triangular line leading to a vent located on the front of the cabinet allowing a positioning close to the rear wall (40 cm minimum). Absence of internal parallel walls reducing the formation of standing waves and allowing the use of a minimum of absorbent material.
Tweeter installed in an insulated volume guaranteeing a total inertia and avoiding any mechanical-acoustic intermodulation with the woofer.
Cabinetry in 19 mm MDF assembled under press. Rounded vertical edges on the front avoiding edge effects, wide fillet on the top rear horizontal edge in line with the style of the current range. Adhesive felt surrounding the loudspeakers to minimize early signal reflections on the cabinet and thus ensure better directivity control.
FILTERING:
2 ½ ways,
6 – 12/12 dB/octave. Cut-off frequencies at 300 and 2800 Hz. Carefully selected audiophile quality components.
LOUDSPEAKERS :
BOOMER/MEDIUM :
All new 13 cm manufactured under JMR specifications derived from the one used for the EUTERPE and the BLISS Jubilé. It uses a long fiber paper cone. The back of this optimized profile cone receives an absorbent treatment that improves its internal damping while retaining the universally recognized tonal qualities of the paper. It has a 30 mm coil on a ventilated aluminium support giving it a good power handling and a powerful and fast bass. Its core uses a copper ring to linearize its impedance and significantly reduce its harmonic distortion rate. Its rubber suspension receives an absorbent treatment on a portion of its profile in connection with the cone to improve its behavior in the full medium. It has an aluminum bowl whose profile perfectly clears the back of the cone. His speeder is ventilated.
TWEETER :
Textile dome tweeter using a 25 mm coil and a neodymium magnet in a small chamber tuned for a low resonance frequency of 650 Hz. It has a very wide and particularly linear response curve, and its directionality is not very pronounced and very progressive off axis. It has an injected ABS front panel with a pavilion profile for better performance and optimal directivity. This tweeter offers a very nice dynamic range and a lot of detail without dryness or harshness, qualities that are essential to meet the musical specifications of a JMR speaker.
STRONG POINT OF USE :
Thanks to a very low directivity, you can enjoy LUNNA without a complex set-up within its environment. This great quality means that you don’t need to converge the two speakers to the ideal listening point to get the most out of its performance. The LUNNAs can be pinched very slightly in order to make the most of the system’s phase.
The spacing will be determined experimentally. In theory, the ideal distance is about 2 m from axis to axis, but this distance can be reduced or increased depending on the acoustic conditions and the dimensions of the listening room. To achieve a deep, well-built stereo image, make sure that the speakers are at least 40 cm away from the side and rear walls.
These loudspeakers are supplied with chrome-plated steel decoupling tips and tailpieces. The inserts on the cabinetry are in M6.

ACOUSTIC CHAMBER :
Load type: Tuned triangular line leading to a front noise vent.
Cabinetry in 19 mm MDF with rounded edges, assembled under press to guarantee a total inertia to the structure.
The axial fixing of the bass drivers allows the tensioning of the cabinet walls, and ensures uniformly distributed mechanical forces between the loudspeaker basket and the baffle support, which dramatically improves the transient response of the system.
The use of internal viscoelastic absorbers transforms the vibratory energy into heat, without loss of micro-information.
BOOMERS/MEDIUM :
2 × 130 mm. Zamak bowl, flat and airy spider, ventilated double magnet, carbon/kevlar non-woven hypergraphic cone, anti-vortex ogive for the midrange, suspension with high return power and high damping for powerful and fast bass.
25 mm moving coil on kapton support.
Mechanical tensioning by means of a stainless steel threaded rod bolted to the center of the magnetic core and to the bottom of the cabinet.
TWEETER :
All new 28 mm dome tweeter in impregnated silk, ensuring a very linear response and a real dynamic range of the highest order (fine dynamics reproduced with great accuracy and large level differences very well respected, without projections or hardness). Double neodymium magnet, non-ferrofluid air gap. Tuned rear chamber ensures a very low resonance frequency (700 Hz) and perfect transient damping. Front panel with machined aluminum bell mouth to ensure a perfectly stable mechanical reference for the ultra-light mobile crew. Very little directionality and very regular ensuring a very nice energy off axis. Very low distortion rate, typically less than 0.05% between 3 kHz and 25 kHz.
Turned solid beech head with a geometry that optimizes the polar coordinates of the loudspeaker, it rests on an oblong spacer for a three-point connection to the main cabinet to avoid any micro-displacement.
Optimized tweeter positioning in height and depth to ensure precise dynamic phasing at the connection with the bass/midrange at 3 kHz. The temporal response is thus exact, the fundamental and the harmonics being reconstituted in perfect time concordance. The accuracy of the timbres is thus perfectly respected, and their fluidity is remarkable.
FILTER : Type of filtering: 2 ½ ways: 6 – 12 -12 dB / octave. First and second order.
BOOMER : Low pass 600 Hz at 6 dB/octave
MEDIUM/BOOMER : Low pass at 3000 Hz at 12dB/octave no bass filtering. The two bass drivers work in parallel and in phase below 600 Hz.
TWEETER : The high pass filter at 3000 Hz at 12dB/octave.
RC circuit (capacitor resistor) in order to linearize the impedance curve of the speakers, and minimize the impedance variations seen by the amp on the whole spectrum.
Hand-assembled filter without printed circuit board, components are oriented and soldered with silver solder directly to each other to avoid any insertion loss. They are glued on a plate of anti-vibration material, and are placed as far as possible from any electromagnetic disturbance. Components sorted by pair with a tolerance of 1%.
Silver armature capacitors with HP1132 silver/copper cable termination marking the winding direction of the silver foil. Self à air sur support ferrite à faible résistance ohmique utilisant un câble cuivre désoxygéné de forte section, pour un grave rapide et sans tassement de dynamique. Non-inductive ceramic resistors with high current carrying capacity.
All internal wiring is done by our HP1132 cable (crossover component connections, capacitor terminations and direct connection to the loudspeaker, soldered directly to the terminals); the HP 1132 cable is made of a large crystal silver/copper alloy. It has three layers of insulation, a first layer of Kapton coating and a second layer of wrapped Teflon before an outer sheath of polyamide. This top-of-the-range cable allows a very beautiful richness of the timbres, combined with a great transparency and a perfect linearity on the whole audible spectrum.
ADVICE FOR USE :
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 2.5 m from axis to axis, but this distance can be reduced. To achieve a deep, well-built stereo image, make sure the speakers are at least 50 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.
