OUR PASSION DRIVES
THE TRUE SOUND

Our
Technology

The explosive power that starts from the amplifier is delivered to you through the speaker with rich and clear sound.

For the ultimate sound experience, our engineers create the best possible sound environment for you with its sophisticated technology.

Components

01

THE ORIGIN OF POWER:
AMPLIFIER

KRELL Automotive's amplifiers are not just electronic components, but audio itself. KRELL has adopted the same concepts used in home audio design to realize high-end car audio using its unique technology. Our excellent amplifier technology creates unique, rich and clear sounds.

  • 20A class high current and voltage boosting power source for high output

  • High-end floating-point operation DSP for high-resolution digital processing

  • Gold-plated copper bar for high current supply to the amplifier circuit

  • Power supply capacitors custom-tuned for KRELL special audio

02

EMOTIONAL RESONANCE: SPEAKER

The speaker diaphragm is a very important factor that determines the nature of the audio’s sound. KRELL Automotive has partnerships with Kurt Müller GmbH & Co. KG and Mogami, which are the world leading manufacturers of diaphragms.
Depending on the model of each car, the size and number of speakers will be different and will give you a perfect sound experience optimized for your own car.

PREMIUM DIAPHRAGM MATERIALS

Honeycomb
Honeycomb is polyhexagon-patterned material made of multilayered Kevlar. It is a new material structure made with a special high-strength fiber used in body armor for Hi-Fi home audio applications. Its lightweight and highly rigid characteristics deliver solid and realistic bass with the least distortion.
PP Composite
PP Composite possesses higher rigidity and faster delivery speed than general PP. It delivers a neutral and warm tone with a strong mid-ranged sound.
Siltec
Siltec is a special material coated with metal powder on pulp. It suppresses the split vibration better than the typical pulp, hence, it has less energy loss and delivers very delicate and bright sounds.

Tuning Sound System

01

FULLY EXPERIENCED AND QUALIFIED

Our sound engineers are professionals with extensive experience, and are committed to delivering the original and emotional sound. After about two years of delicate tuning, a car sound system is completed.

02

ACOUSTICAL LABORATORY

We are making the world's best sound system in world-class acoustics labs.

Reference Listening Room
This is used as a critical listening room to ensure that the recorded music can be played correctly without any distortion. After listening and checking every detail of the recorded sound in the room, we design systems that can produce the same sound as the original one.
Anechoic Chamber
One of the characteristics of acoustic is that it is very sensitive to the environment, hence, it is very difficult to measure. An acoustic anechoic room is a space without any sound reflections and noises, and designed to enable precise analysis of the acoustic characteristics of a vehicle speakers.
Dynamo Anechoic Chamber
In the actual driving environment, the vehicle is located on the road with its noise from the engine, and the ground reflects various noises. An acoustic anechoic room simulating this environment has a 99% reflective floor and an NVH(Noise, Vibration, Harshness) dynamo facility capable of driving up to 200 km/h.

Sound Features

01ENHANCED SURROUND SYSTEM:
LIVE DYNAMIC

Live Dynamic is a sound algorithm technology that achieves the original sound production. The system delivers the original sounds’ impression to audience by restoring the digital audio’s dynamic information, which is compressed to 16 bits, into 32 bits. Live Dynamic delivers separated sound signals in Concert mode or Natural mode according to the dynamic variation. Concert mode improves the sense of space through multi-channel reconstruction. Natural mode enhances dynamics through stereo reconstruction.

02NOISE CANCELATION

It eliminates unnecessary noise while driving to provide an enjoyable driving experience.

Active Noise Control System
The Active Noise Control System generates a sound signal that is the opposite of the noise signals coming from the engine, which masks the unwanted noise.

Active Road Noise Cancellation
The Active Road Noise-Cancelling System eliminates noises generated by the engine, tires, wind outside the vehicle, and the road.

03PERSONAL ENGINE SOUND SYSTEM

PESS is a technique for creating a virtual engine sound based on driver acceleration. You can use the interface to set the character and tone of the engine sound.

04CONVERTIBLE SOUND SYSTEM

Convertible Sound System is an acoustic sound system optimized for passengers. The speaker automatically rotates according to the position of the passenger and delivers a three-dimensional sound. The mood lighting blends with the music and fills the car with full of emotions.
