Jean Marie Reynaud (JMR) Folia Jubile - Black Satin

For the development of FOLIA JUBILEE, we established very precise requirements:

It had to be able to be associated with moderate powered electronics. It could not impose positioning constraints in a room. And above all, it had to meet the long established JMR criteria of musicality and sensitivity. And all within in a very reasonable budget. We are pleased to report that the FOLIA JUBILEE has achieved a complete success in meeting all these criteria, which are difficult to combine.

Very lively and playful, the Folia Jubilee knows how to handle the colors and tones of musical instruments and human voices with surprising ease for a speaker of its size and cost. The mid-range is rich and luminous, at the same time precise and very physical. The low end is astonishing in view of its volume, and there is neither strain nor noticeable limitations in this register.

DESCRIPTION

Its loading principle makes it possible to use almost no damping material, so the lowest octaves have excellent readability: there is no feeling of the constriction often present when using such a small sized enclosure.

Because it is designed so that it can also be hung on the wall or leaned against it, you can obtain even more body and energy in the low register in these locations. The laterally and mirrored event ports diffuse a complementary and very homogeneous sound field in the low-mid-low register so that the presence of the wall behind them will not disturb the readability in this portion of the spectrum.

The stereophonic image is stable and precise and opens wide beyond the loudspeakers, indicating a rigorous phasing of all the components.
The latest optimizations for this Jubilee version have allowed us to further improve the performances of this small and very endearing loudspeaker system. Thus, the use of an aluminum basket, more rigid than the ABS one, allowed us to improve the pulse response and therefore the dynamics. The phase plug on its tweeter improves its directivity and its linearity. The large-sized velvet felt on its front baffle allows it to diffract the first reflections on the cabinet and improves the quality of the sound stage. We took the opportunity to modernize its aesthetics and give it a more upmarket character thanks to the rounded edges of its front as well as the large roundedness of its horizontal rear edges. Finally, it is offered now in two finishes: black satin and a very beautiful lacquer tri-layer pearly white.

The FOLIA JUBILEE should please music lovers seeking a sound with a refined tone and without artifice or caricature. It will provide hours of listening without fatigue and weariness and in all points faithful to the sound philosophy of Jean Marie Reynaud’s products can be reduced or increased.

The mirrored lateral event port should be installed toward the inside of the stereo image when distance between cabinets is 1.5m and upper, and outside of the image when below 1.5m.

TECHNICAL INFORMATION

ACOUSTIC ENCLOSURE:

Its loading system is made of two asymmetrical tuned cavities leading to a lateral event port positioned in mirror for the pair (event port looking at each other in the center of the stereo image). Again, this very specific tuning system allows the FOLIA JUBILEE to be hung on a wall or leaned against it. Because there are no parallel walls in the enclosure, it allows us to use a strict minimum damping material thus preserving the speed and natural articulation of the low mid and bass frequencies.
Its tweeter is installed in the middle of the front baffle and so vertical and horizontal directivity is notably homogeneous and symmetrical.
The addition of a large adhesive velvet felt on the front baffle around the woofer and the tweeter is diffracting all first reflection and improve phase and directivity out of axes of the system.
19mm MDF assembled under press to guaranty a perfect stiffness of the enclosure.

WOOFER:
13cm paper cone woofer, aluminum basket, flat decompressed spider, 25mm coil on Kapton support, double magnet system and rubber surrounding of extreme quality offering fast and strong bass response.

TWEETER:
25mm pure silk, dome double neodymium magnet cooled by a rear tuned cavity that also lower the resonance frequency and improve the transient damping time.
Half moon shape phase plug to improve horizontal directivity and overall linearity.

CROSSOVER:
12db/octave, crossover frequency 3200hz.
Ferrite coil with large section pure copper wire for low distortion, low resistivity and good power handling. All components are soldered directly one to the other without the use of printed circuit board and using silver RoHs soldering. Polypropylene capacitors and high-resolution ceramic resistance. Specific pure copper wire of 1,2mm section for the woofer and 0,8mm for the tweeter.

TIP:
Thanks to a very low directivity, it is not necessary to aim the two speakers at the ideal point of listening, but rather toeing them in slightly in order to benefit from the Better phase of the system.

The insert installed at the back of the cabinet, allows you to hang the FOLIA JUBILEE against the wall. The distance between the ground and the bottom of the cabinet should about 50cm but can be increased in case of a stand up listening position.
Spacing should be determined experimentally. The theoretically ideal is in the vicinity of 2m but this distance can be reduced or increased. The mirrored lateral event port should be installed toward the inside of the stereo image when distance between cabinets is 1.5m and upper, and outside of the image when below 1.5m.
