The new CENTAURI 1706 is the first planar headphone, in the development of which we strived to offer something different than what has previously been found on the planar headphone market.
The dimensions of the diaphragm and the inherent deformability of the structure that supports the rows of magnets result in a low dynamic efficiency of the headphone system, which tends to to deform under the heavy strain on the membrane, which is by nature not very light and has a certain inertia. This results in a sound image in which the high-energy dynamic contrasts in the middle and low range are weakened and that Sense of rhythm is lost.The other major problem related to the size of the driver is that there is no room for the pressure equalization holes between the acoustic chambers of the headphones, so one has to resort to simplified designs that provide a sealed ear chamber, which is a Imbalance in the membrane movement is created. This design feature also leads to a major problem related to our ears: as soon as the headphones are placed in a sealed chamber with a cushion, the eardrum experiences pressure and changes the high-frequency response , which triggers the typical cave effect.
With the new Centauri 1706, we focused on finding a light but very rigid support plate for the planar driver that does not deform under the dynamic load of the powerful planar driver with N52 class neodymium magnets on both sides of the diaphragm. We have introduced a new composite material called Texalwood, which involves pouring epoxy resin into a panel of poplar plywood and two panels of Texalium (aluminium-loaded fibreglass). This new beam is designed to it houses the ventilation system of the VPS pad and the pressure equalization holes, so that the membrane can move with symmetrical resistance in both directions of movement.
It is important to understand that the pad makes up 50% of headphone designs and cannot be easily adjusted from one design to another.
Centauri is a large headphone that uses the company's proprietary Ventilation Pad system through a Outwardly curved trumpet can be used in place of the usual ventilation openings.
Made of Alcantara and leather, the Centauri pad is large, leaving room for large ears and creating a listening space that creates an impressive soundstage.
The Centauri pad fastening system is another novelty at Spirit and allows for quick release thanks to magnets attached to the frame.
This allows you to carry out replacement and normal maintenance extremely easily.
To maximize the dynamic performance of the planar headphone, which is the real Achilles' heel compared to traditional dynamic systems due to the limited range of motion of the planar diaphragm, we took advantage of the concept of inertial frame, which further optimizes the dynamic efficiency index of the system.
To trigger the concept of inertial frame, it is necessary to achieve a minimum mass of the static parts of the headphone frame in order to provide adequate inertia when subjected to the thrusts determined by the accelerations of the planar driver membrane.
This inert mass was achieved by using the technique of multi-layered wood system introduced in Mistral, which envisages a laminated wood structure, which allowed the selection of a compact and rigid walnut wood in this project.
Centauri offers exceptional comfort thanks to the revolutionary stainless steel headband that can be shaped to apply the desired pressure on the ears and the exhaust band that adapts to your head.
