ASYMMETRIC DOME SUSPENSION

Custom-Shaped

The asymmetrical suspension provides a more linear resonance-free guiding of the dome.

A soft dome works as a piston in low frequencies (1 – 8kHz), above that, the centre of the dome stands still (at last should be, depends on the quality of the coating, both how it’s applied and the recipe)

The more higher frequencies are reproduced the less the dome itself emits sound. At very high frequencies, only the area around the voice coil (on both the dome and suspension) emits sound.

The custom shape of the suspension helps to have a better dispersion, as waves travel freely to the side

RASC COATING RECIPE

Key Control

After hundreds of hours of experiment, our very own coating recipe brings perfect break-up control and the most accurate, smooth sound reproduction.

OUTPERFORMING LARGE FERRITE MAGNET SYSTEM

Φ100mm, Extra Large!

The large ferrite offers a high magnet force, similar to smaller neodymium magnets, but for a significantly lower cost (which helps us achieve to set a more attractive retail price).  It is as well more eco-friendly using ferrite magnets. 

A comfortable efficiency of 91dB is reached with this system. Also, the large mass of ferrite and the metal part absorbs more heat from the voice coil and helps for better cooling.

BCD (BACK CHAMBER DAMPING)
RESONANCE-FREE DESIGN

Large Back Chamber,
With Special Simulated Asymmetric Rim Construction

Made from structured rigid plastic, the design of the asymmetric rims is precisely simulated for the purpose of resonance absorption.
Through BCD, it helps to get a low resonance frequency of 560Hz.

INVERSED DOME SUSPENSION

Perfect Imperfection

The inversed suspension provides a more linear resonance-free guiding of the dome.

The more higher frequencies are reproduced the less the dome itself emits sound.

The custom shape of the suspension helps to have a better dispersion, as waves travel freely to the side

ARID+ Patented Technology

Next-Level Innovation

Our 75mm midrange works like a piston between 400Hz and 5kHz, so they are no breakup modes.

ARID+ is a special-shaped dome, where the surface has been designed with the simulation software Comsol, to avoid any resonances and to guide the waves behind the ARID to be then absorbed in the large back cavity.

Due to the lack of damping material behind the dome, high frequencies are extended and resulting in what we aim for “tonal balance”. 

OUTPERFORMING LARGE FERRITE MAGNET SYSTEM

Φ140mm, Extra Large!

The large ferrite offers a high magnet force, similar to smaller neodymium magnets, but for significant lower price (which helps us achieve to set a more attractive retail price).  It is as well more eco-friendly using ferrite magnets.

A comfortable efficiency of 91dB is reached with this system. Also, the large mass of ferrite and the metal part absorb more heat from the voice coil and helps for better cooling.

BASALT PROPERTIES

From Lava Stone, to the Best Drivers

Basalt is mainly found on cooled-down lava or magma flow, which is a dark grey coloured so-called igneous stone and found in huge quantities all over the world.

Transformed basalt fibres has interesting properties which makes it suitable for the use in loudspeaker diaphragm.
Its Young modulus is also significantly stronger than glass fibre, and much stronger than Kevlar.
We thus use it also for its sustainability, as it’s a non petrol-based material.

BASALT SANDWICH CONSTRUCTION

The speed of stiffness

Basalt is unique in the world of high-end audio and has never been used before.

It is extracted from lava stone, which exists naturally in abundance on earth, and doesn’t need to be produced from petrol: It is recyclable, and thus eco-friendly.

In order to get the right damping within the membrane, we build the cone as a sandwich, made from a Basalt fibre fabric as the top layer,
a polymer glue and a felt in the middle; and a specially customized foam-based cone as the bottom layer.

As a result we get a membrane which is stiff, light, well damped and with a good speed of sound propagation.

ASYMMETRIC OPEN-BASKET DESIGN

Optimised for best results

We made the most vented basket possible in order to maximise the open design benefits, simple is that!

OUTPERFORMING LARGE FERRITE MAGNET SYSTEM

Extra Large!

The large ferrite offers a high magnet force, similar to smaller neodymium magnets, but for a significantly lower price (which helps us achieve a more attractive retail price).  It is also more eco-friendly using ferrite magnets.

For example, a comfortable efficiency of 91dB is reached with the BSC woofers. Also, the large mass of ferrite and the metal part absorbs more heat from the voice coil and helps for better cooling.
