What JMR Say:
When designing the CONCORDE SUPREME, JMR's idea was to achieve the widest bandwidth and the most precise transient response, while keeping it user friendly in terms of cabinet size.
Listening to the CONCORDE SUPREME is, in more ways than one, an unforgettable experience. The sense of reality it conveys when recreating music is probably its most striking characteristic.
The timbres and their harmonic structure are so truthful and vivid that each instrument is portrayed in the most life-like and natural way. Those who enjoy live music will find them astonishingly familiar, with that feeling of “déjà-vu” springing from their concert hall experience.
The perfectly designed loading system of its amazing woofers allows the CONCORDE SUPREME to go extremely low, and to do so without any cabinet resonance, and without blurring low frequencies.
Bass is deep, naturally sweet and bouncy, with remarkable drive. Its midrange allows timbres to bloom naturally. Fast, with low directivity, a total absence of coloration, and exceptional linearity, it portrays the artistic intentions of the performers in the most accurate yet relaxed way. The recording venue is recreated faithfully.
Its double ribbon tweeter adds to an already impressive ensemble. Perfectly in phase with the midrange driver, it allows the treble to shine and to melt smoothly with the rest of the music,recreating a coherent wave front. The strain associated with some tweeters is completely absent from such a design.
Though they require a reasonably wide room to give the best of themselves, setting up these speakers up is quite easy, thanks to the painstaking attention that went into cabinet damping.
Also, in order to allow them to really shine, and to benefit from their startling dynamics in the low frequencies it is recommended to match them with amplifiers endowed with a high current capability.
Tuned triangular transmission line for the woofer.The midrange driver is encased in a dedicated enclosure,tuned with a second enclosure through a Helmholtz resonator in order to eliminate the main cabinet resonance. Tweeter is unbaffled. Adjustable spikes are provided, as well.
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 and midrange speaker’s cones are made with carbon and Kevlar fibers embebded in a graphite compound “hypergraphe”. Because their frequency response is very flat and without phase errors the crossover is as simple as possible. The ribbon tweeter is handmade housed in a solid wood head designed to produce a very regular polar diagram.
2 x 6.5” diameter units. Zamac basket, double magnet.
Aerated flat spider, 1.5” moving coil wound onto kapton support. Ventilated core.
5’’ diameter. Zamac basket, double neodymium magnet, aerated flat spider. 1” moving coil onto aluminium support.
Double unbaffled ribbon tweeter, overall dimension of the two ribbons corresponding to the gold number. Hyperbolic front frame giving a very low directivity.
6 dB, 12 dB and 18 dB octave.
Cut-off frequencies: 330 - 2800 Hz.
Large section copper air-coils, tin-framework polypropylene capacitors with low tolerances for the tweeter’s crossover.
Point-to point-wiring, no circuit board. All sections, bass, midrange, treble, are isolated from one another to prevent magnetic and mechanical interference and housed in a sealed cavity at the bottom of the cabinet.
Real Aniegre-veneered medite material on both sides. Sandwich structure for the back of the cabinet. Assembled under press to guarantee a completely inert structure. Optimised internal damping. Rounded edges in solid beech wood to limit diffraction effects. Baffle support for the woofers decoupled from the enclosure to avoid transmission of energy to the overall structure.
