JMR Euterpe Jubile Floorstanding Speakers

€2,750.00

The Euterpe Jubile speakers have undergone a major overhaul resulting in a greatly improved stereo soundstage, articulated bass and a very detailed mid to high frequency response. They are extremely versatile and impressive, providing hours of listening without fatigue and perform with an ease and musicality expected by JMR and have received the same care and attention plus optimisation attributed to the complete range of JMR speakers.

FEATURES

Loading principle: Tuned triangular transmission line, lacking internal parallel walls reduces the formation of standing waves and allows the minimum use of absorbent material. The inside of the cabinet has been coated with a viscoelastic compound which transforms vibratory energy into heat and reduces the use of absorbent foam within the cabinet improving the low to mid range frequency response. The tweeter is installed in an isolated internal enclosure guaranteeing total inertia and avoiding any mechanical intermodulation with the woofer. Mechanical tensioning of the woofer is provided by a threaded rod made of non magnetic stainless steel which passes from the rear of cabinet and is attached to the rear of the woofer. This axial attachment of the woofer makes it possible to strengthen the rigidity of the cabinet and ensure mechanical forces are uniformly distributed between the loudspeaker basket and the supporting cabinet, dramatically improving the transient response of the speaker.

Velvet Felt Surround A non reflective velvet felt surround, surrounding the woofers and tweeter, diffracts first reflections on the cabinet and improves phase, directivity and soundstage.

Woofer: The Euterpes driver is made of 170mm long fibre Gaussian profile paper cone and is treated using an extremely effective damping material. Its impregnated dust cap is assembled at the rear of the cone in order to avoid the frequency surge at the end of the bandwidth. It has a 30mm coil on a ventilated aluminium support, its aluminium frame clears the rear of the cone. Its spider is also ventilated to improve the cooling of the coil and thus significantly lower its distortion rate. It is equipped with a double magnet to increase the concentration of the magnetic field onto the voice coil. Its suspension is made from a rubber and foam compound which has an optimised profile in order to obtain a very fast response time when subjected to extreme variations in the low and mid frequencies.

Tweeter: This tweeter is a 28mm impregnated silk dome tweeter and is the same as the one used in the CANTABILE JUBILE model. Its directivity is naturally very low, which removed the need for the use of a phase plug. Its linearity is exemplary and its internal damping optimal. It is powered by a powerful neodymium magnet operating with a very low resonant frequency which allows a cutoff frequency at 2800hz in 12db / octave. The tweeter is mounted to a machined aluminium front frame using a specific soft glue which reduces mechanical interference and further improves its directivity and performance.

Crossover: 12dB / octave, Crossover frequency at 2800 Hz. A Ferrite air coil with very low resistance uses 1.5mm oxygen-free pure copper winding cable for a fast, non-compressed low end frequency response. All of the crossover components are hand crafted, measured, matched and sorted into pairs to within a tolerance of 1%, this selection process plus the pairing of the components, enables JMR to produce perfectly matched speaker pairs.

Resistors & Capacitors: Non inductive ceramic resistors are used along with Silver capacitors which indicate the directivity of their silver foil windings.

Hand Assembly: The crossover network is assembled entirely by hand and mounted on an anti-vibration plate positioned as far as possible from any magnetic and vibratory interference. All components are soldered directly one onto the other using silver ROHS (Reduction of Hazardous Substances) soldering.

Internal Wiring: All interconnections use JMRs HP1132 silver/copper cable, soldered directly to the loudspeaker binding posts. This high end cable provides a true linear response over the entire frequency range of the speaker. It produces rich tones with an extremely high degree of resolution and transparency that lacks any harshness. WBT Block type speaker terminals allow the use of the following connectors, Spade, Banana or Bare cable.
