Drivers

Every RHA driver is developed in tandem with its housing; the components are rigorously tested, tuned and refined simultaneously to ensure that they work together to achieve the highest possible performance standards.

Dynamic driver

Each dynamic, or moving coil, driver used in RHA products is custom engineered and tuned to produce the highest quality sound reproduction.

At the rear of the array, a stationary magnet generates a constant magnetic field

Electronic signals are received from the source device, and are passed through the voice coil: receives electric audio signals which create an opposing magnetic field, causing movement.

The diaphragm, a flat, rigid component attached to the moving voice coil rapidly vibrates, which creates sound waves.

  • Magnet: Generates constant magnetic field

  • Voice coil: receives electric audio signals which create magnetic field causing movement

  • Diaphragm: Attachment to voice coil causes rapid vibration which creates sound waves

DualCoil™ driver

As used in the T20, T20i and T20i Black, DualCoil™ technology is engineered for performance capabilities beyond conventional moving coil drivers.

Annular magnet: Generates constant magnetic field

Outer voice coil: Moves to create upper midrange and treble frequencies

Inner voice coil: Creates movement to generate bass and lower mid frequencies

Diaphragm: Attached to both voice coils, with specific areas of the diaphragm generating different frequency bands

Crossover: Divides frequencies into two bands, below 2.2kHz and above 2.2kHz

Ceramic Plate Transducer

Featured in the CL1 Ceramic's dual driver configuration, the ceramic plate driver operates using the piezoelectric effect to produce outstanding treble and harmonic tones alongside the CL Dynamic driver.

Featured in the CL1 Ceramic's dual driver configuration, the ceramic plate driver operates using the piezoelectric effect to produce outstanding treble and harmonic tones alongside the CL Dynamic driver.

The transducer is made up of three layers, with two outer metal layers surrounding the ceramic plate from which the technology draws its name.

To create sound waves, the electrical audio signal travels from the rear silver layer, through the ceramic plate, to the front zinc layer. 

The charge passing through the low-conductivity zirconium dioxide causes it to contract and expand, manipulating the zinc layer to produce sound waves.

Dacamp L1

The RHA Dacamp L1 is unique in its class, featuring dual DACs and class AB amplifiers for powerful, high-resolution audio processing up to 32-bit/384kHz PCM and DSD256 formats for headphones from sensitive IEMs to fullsize studio headphones.

Dacamp processing

a. Digital audio signals are sent from source device.

b. Each channel is independently processed by a ES9018K2M DAC and class AB amplifier in order to transmit a pure, balanced sound signal to each headphone or speaker transducer.

c. Each channel is fully grounded and balanced, leading to a balanced Mini XLR output, eliminating the risk of cross-channel interference and distortion.

Noise Isolation

In order to keep your audio in, and external noise out, all RHA in-ear headphones are designed with high-level noise isolation properties.

Noise Isolation

RHA products use passive noise isolation; combining advanced housing designs and premium ear tips to create a physical barrier in the ear to protect from external interference. This method avoids the technological and sonic distortion problems faced by many active noise cancellation methods.

Acoustic Testing

As part of RHA's ongoing commitment to true-to-life sound, we conduct advanced acoustic research into the nature of sound reproduction and the capabilities of our products to accurately recreate original audio.

Pioneering laser spectography

To develop RHA's DualCoil™ dynamic driver, RHA engineers used precise techniques to optimise accuracy and ensure efficient crossover separation. Our engineers needed to develop a membrane that could tolerate the stresses of both rapidly vibrating coils. Prototype drivers were tested using a laser vibrometer to precisely measure the displacement of the diaphragm's surface at various frequencies.
