Sound technology

Dedicated Low-Frequency Driver

IBUKI features an exclusive liquid crystal polymer dynamic driver. Specifically tuned for low frequencies, it delivers powerful, precise bass performance tailored for high-end audio enthusiasts.

Precision-Optimized BA Drivers

We selected premium Balanced Armature drivers optimized for every frequency. These handle everything from the low-mid range to the high range, ensuring crystal clarity across the entire spectrum.

Ultra-High Frequency EST Driver

An Electrostatic driver handles the ultra-highs. It creates a seamless transition between driver types, offering a smooth, cohesive soundstage without any noticeable gaps between the different components.

Gold-Plated OFC Ring Chamber

A gold-plated Oxygen-Free Copper ring chamber provides exceptional vibration damping. This enhances low-frequency expression, resulting in rich, controlled, and deeply resonant bass textures.

3D-Printed Sound Conduit

Utilizing advanced 3D printing, the integrated driver holder and sound conduit ensure perfect continuity. This precision engineering maintains sonic integrity as sound travels through the internal structure.

High-Precision Crossover Circuit

The passive crossover combines high-quality capacitors with thin-film resistors. This optimal tuning manages signal flow perfectly, ensuring each driver performs at its absolute peak without interference.

Electromagnetic Shielding

Using Brise Audio’s HCNT and electromagnetic wave absorption materials, we shield the drivers and transformers. This prevents interference, resulting in superior sound separation and incredible transparency.

Acoustic Internal Damping

Specialized felt sound-absorbing material sits behind the dynamic driver to eliminate internal reverberation. This reduces adverse effects on other drivers, protecting the overall purity of the sound.
