The final Audio SONOROUS IV presents clear sound quality and a vast, deep sound stage. With the synergistic effect of a hybrid design that merges balanced armature with a 50mm diameter dynamic driver unit coupled with BAM mechanism, we've achieved a clear, vast sound stage with depth to it. With these, the music that seemed to be localized inside our heads with existing headphones vibrates over
a large space.

Newly developed 50 mm φ dynamic driver

A driver unit with a diameter of 50mm, newly designed for SONOROUS. By increasing the precision of the parts, it has become possible to make the gap between the magnetic circuit, the pole piece and the yoke narrower than with common products. A powerful neodymium magnet is coupled with this,
making for a high magnetic flux density. The result is clear sound quality.

We've re-examined the shape of the tangential edge and have employed a lightweight diaphragm with a heightened responsiveness to micro-signals.

The voice coil is copper-clad aluminum wire CCAW. Clear, crisp bass tones are achieved with the combination of a magnetic circuit with a high driving force and a light vibration system.

So as not to inhibit the sound emanating from the driver unit, and so that there is no unnecessary added reverberation, a form that is as slim yet as strong as possible has been pursued. This contributes to clear
sound quality.
