Design philosophy of a revolution in the field of planar headphones

To date, the development of planar headphones focuses on the ever-increasing driver which, inevitably, plays a role as a supporting frame.

The dimensions of the membrane, together with the intrinsic deformability of the structure that supports the rows of magnets, leads to a low dynamic efficiency of the headphone system, which tends to deform under the strong stresses of the membrane which, by its nature, is not very light and has a certain inertia.

This results in a sound in which high-energy dynamic contrasts are mitigated in the mid-low range, losing the sense of rhythm.

The other big problem related to the size of the driver is that there is no space left to insert the pressure compensation holes between the acoustic chambers of the headphones, forcing to fall back on simplified designs that provide a sealed ear chamber which creates an imbalance in the membrane movement.

This design feature also triggers a major problem relating to our ears: once the headphones are placed with a pad in a sealed chamber, the eardrum undergoes pressure and modifies the high frequency response, triggering the typical cave effect.

An evolved Pad for an important headphone

It is important to understand that the pad represents 50% of headphone designs and cannot simply be adapted from one design to another.

Centauri are large headphones and provide for the insertion of the proprietary Ventilation Pad System through an outward expansion trumpet, instead of the usual ventilation outs.

Centauri's Pad, realized In Alcantara and leather, it is large, leaving room for large ears and creating a listening room capable of generating an imposing sound stage.

The Centauri pad attachment system is another novelty for Spirit and provides for quick release via magnets arranged on the frame.

In this way you will be able to carry out replacement and ordinary maintenance with extreme ease.

A Multilayer Wood system frame in walnut and Texawood driver rack to optimize dynamics

To maximize the dynamic performance of the planar headphones, which represents the real Achilles heel compared to traditional dynamic systems, due to the limited range of motion of the planar membrane, we have also exploited the concept of inertial frame which further optimizes the system dynamic efficiency index.

To trigger the inertial frame concept it is necessary to reach a minimum mass of the static parts of the headphones frame, in order to offer the appropriate inertia when it is subjected to the thrusts determined by the accelerations of the planar driver membrane.

This inertial mass was achieved by exploiting the Multilayer Wood system technique introduced in Mistral, that provides for a laminated wood structure, which in this project has provided for the selection of a compact and rigid walnut wood.

Open headphones? Semi-closed or closed cap? Spirit helps you choose the one that best suits your needs.

Open headphones offer maximum naturalness and openness of sound but do not insulate from external noise and disperse the sound towards the outside.

Semi-closed headphones are open headphones with shields to partially limit the transmission of sound to and from the outside. the sound remains very airy and natural and you can listen without disturbing those around you.

Closed-back headphones create sound isolation from the outside world, have great low-frequency extension but are less natural and lose that airiness that makes you forget you're wearing a headset
