Genesis Design, Explained

 

Baffle

Where the speaker lives within a headphone

Most open back circumaural dynamic headphones feature drivers surrounded by sheer meshes or screens that allow air to freely escape on-axis with the plane of the driver’s front face. In theory, the benefits of this approach are the most ‘open’ sense of space with the sharpest transient impulse. The cost of this approach however is a loss of low-frequency extension and a blunted follow-through of dynamic energy due to a lack of frontwave pressurization given the ease that air pressure can exit the enclosure. The Genesis baffle is different in several key areas:

 

Mechanical Unity

Given that Genesis shells are unibody in design, the baffle itself is mechanically coupled to the entirety of the enclosure. This achieves an optimal sense of tactility with the highest possible conduction of driver energy, without problematic baffle resonances or break-up at higher volume levels. 

Proximity Control

Genesis baffles are slightly sunken behind the earpad mount for improved coherency between the midrange and treble and a less ‘inside the head’ soundstage. Many headphone designs utilize deep earpads to achieve targeted proximity, but the cost of this approach is increased reflections across the earpad walls, which sit perpendicularly to the driver’s front face (a worst-case scenario for the development of peaks and ringing)

Multi-axis Airflow

While our baffle venting is conventionally flush and on-axis with the driver’s front face, it’s also radially vented through side-addressed slot outlets nearest to the earpad mount. Off-axis projection of frontwave energy is allowed to escape or absorb into the soft materials surrounding the driver’s face, as opposed to reflect into the earpad and meet the ear out of phase with the direct wavefront.

Frontwave Pressure Biasing

We utilize low-density hand-cut open-cell foams as a form of acoustic filtration within the baffle seat. This approach yields an airflow scheme that is neither fully open nor fully closed, but tunable and variable. We’ve selected our 2.5lb visco front foam for optimal sonics and airflow, balancing the need for a sustaining, subsonic-reaching bottom end with uncompromised dynamic follow-through for an unprecedented sense of ‘grip’ across the entirety of a dynamic impulse.

Driver

the electromechanical element that transduces voltage into vibration; a miniaturized loudspeaker

Most companies will shave on cost by utilizing weak magnets in the driver motor assembly, leading to a soft, loose, and poorly resolving sound. Our drivers use N52-grade neodymium magnets that approach 1.5T (15,000 gauss), the strongest available of any commercially produced dynamic driver in existence. 

The 300 ohm voice coil assures minimal reactivity from your amplifier’s output impedance for a wide scope of compatibility with upstream components. 


Our drivers also have flexing diaphragm surrounds much like a loudspeaker woofer, giving ultra-high-excursion with minimal cone break-up for unparalleled dynamic nuance regardless of listening level.  


We chose Graphene for our diaphragm material for its clarity of timbre, inherently low material resonance, and super-high rigidity for sound that doesn’t veer far into ommissive or commissive tendencies relative to your component chain.

Damping and Diffusion Tuning

the application of soft materials to fine-tune the presentation of a headphone

Unlike most damping schemes which act to selectively attenuate problematic peaks between the front of the driver/baffle and the ear (causing a veiled sense of dynamics and loss of detail), our drivers are only damped on the rear side.

A stiff adhesive felt patch works to throttle airflow from the central magnet vent for superior projection of upper-midrange frequencies in the center of the image. The peripheral driver vents fire into open air, or into an adjustable array of cotton rolls positioned for ideal projection relative to the anatomy of the ear itself. 


This gives a unique imaging presentation, with the critical upper midrange focus in the center of the image for optimized separation of vocals and instruments within the soundstage. Inversely, where the ear is most sensitive to high-frequency energy, the open peripheral vents allow it to escape or diffuse without directly meeting the ear for incredible HF smoothness without any loss of clarity.

Earpads

A microacoustic environment for your ears

Earpads are every bit as important to sonics as any other part of a headphone’s design - the equivalent to room acoustics in the world of headphones.

 

Our custom earpads utilize firm internal foam for explosive dynamics, supple sheepskin leather for comfort, and a unique bottom-to-top slant for flawless on-axis positioning of the driver’s frontwave plane relative to how human ears are positioned on the skull. The ear cavity shape is subtly flared out as it reaches the head to minimize perpendicular reflections.

 

We painstakingly adjusted every parameter of our earpad design to assure the sonic result is the smoothest, livelist, most spacious possible. Unlike other manufacturers, we don’t divorce our earpad design from our enclosure R&D, rolling the dice on synergy - every aspect of the build was designed with ‘the bigger picture’ in mind.
