Aurum Cantus HARMONY 

 

 

    

 

Harmony je drugi model podnostojećeih Aurum cantus zvučnika. Izradjen je veoma slično kao i vodeći model Supreme, sa najvećom pažnjom i od najkvalitetnijih komponenti. Kvalitetni niskotonski zvučnici u stanju  su da precizno i tačno reprodukuje najniže frekvencije čak do 30Hz, dok visoki spektar pokriva čuveni ribon G1, sa rasponom do 40 kHz, čija mebrana je u stanju da se zaustavi za neverovatne 0,2 msec nakon prestanka impulsa.

Na merenju G1 ribon je pokazao najbolje mere ikada izmerene i zabeležene. Skretnica je sastavljena od skupih i najkvalitetnijih M-Cap supreme MKP kondezatora za visokotonsko, polipropilena za srednje i bas područje. Zvučnik je ožičen najkvalitetnijim Supra kablovima, sa najkvalitetnijim pozlaćenim konektorima za bi-wiring vezu. Kabinet je izradjen od medijapana čija je prednja strana debela 55mm, a bočne 28 mm.

Izgled zvučnika je paraboličan sa jakim unutrašnjim učvršćenjem kako bi se izbegla rezonancija i stojeći talasi. Završna obrada zvučnika je od prirodnog furnira visokog sjaja, koji je 14 puta pažljivo ručno lakiran i brušen sa završnim poliranjem i voskiranjem čime je dobijen najveći mogući duboki sjaj.

  • Midrange:Model:AC165/50C2C,Specification:6.5"(165mm),Sandwich cone ( NON-WOVEN CARBON FIBER+CELL 2mm + NON - WOVEN CARBON FIBER ),φ50mm copper cover aluminum voice coil with flat wire,φ120mm×T20mm Y30 Ferrite magnet,short circuit cooper ring in the center magnet pole, long throw.
  • Woofer:Model:AC200/50C2C,Specification:8"(200mm),Sandwich cone ( NON - WOVEN CARBON FIBER + CELL 2mm + NON - WOVEN CARBON FIBER ),φ50mm copper cover aluminum voice coil with flat wire,φ120mm×T20mm Y30 Ferrite magnet,short circuit cooper ring in the center magnet pole, long throw.
  • Crossover frequency:120Hz and 2000Hz.
  • Crossover’s attenuation slope (per octave):woofer -12dB,midrange -18dB,tweeter -18dB.
  • Crossover parts:M-cap Supreme MKP series capacitors is used for crossover of tweeter,M-cap MKP series capacitor is used for crossover of midrange, and Aurum Cantus MKP capacitor is used for crossover of woofer, nonpolarity electrolytic capacitor is used for emendation circuit of woofer, and also use 5N OFC conductor,metal oxide film resistor.
  • Connective wire:Supra Classic 2.5 cable is used for tweeter and midrange, Supra PLY S/3.4 cable is used for woofer.
  • Absorbing material:Polyester fibre and sponge.
  • Connections:4pcs 18mm golden-plated connector, bi-wiring design.
  • Structure of cabinet:Parabola-shaped cabinet structure. Midrange box and woofer box are completely separate. Inner strengthened braces that are made of 25mm MDF are positioned in the woofer box, 4 places in total. Thus it can fully decrease the cabinet resonance and standing wave of the inside of cabinet.
  • Cabinet material:MDF. The thickness of front baffle is 55mm,the thickness of parabola-shaped side panel is 28mm,the thickness of rear plate is 28mm, the thickness of top plate is 25mm,the thickness of bottom plate is 65mm.

Furthermore, there are rosewood, cherrywood, reflective maple, black walnut and French Sycamore for options. 14 layers high gloss unsaturated polyester resin paint is finished on the surface of cabinet , and manually polishing each layer paint carefully, then it forms high shining surface after polishing with high-speed and waxing.
  • Dimension of the cabinet(HWD):1200mm×293mm×460mm (the height is exclusive of spike and the deep is exclusive of grill).
  • Weight (net weight):60Kg/pc.

 

       Aurum Cantus Harmony Cinema Experience Review

 

                                                     

                                                  G1 waterfall                                                                                           G1

 

Above is the Aurum Cantus G1 waterfall plot over a 4msec window, with a waterfall depth of -30dB. The first 0.5msec is the actual frequency response during the impulse, and the first decay slice takes place at 0.6msec. What is of special importance is that the decay is nearly complete by 0.8msec, of an incredible 0.2msec after the impulse is turned off. Within 1msec, the ribbon diaphragm is completely back to rest. All told, this is the best measured performance this designer has ever recorded.
