Powerful sound with X-Balanced Speaker Unit​

Our X-Balanced Speaker Unit features a non-circular diaphragm, for an increased surface area compared to conventional speaker units. The approx. 79 mm x 107 mm large woofer unit is designed for clear and deep bass sound.

A richer, clearer, deeper experience​

The non-circular diaphragm not only maximises the area of speaker diaphragm but it also increases sound pressure for deeper and punchier bass, less distortion and greater vocal clarity. Altogether, it elevates your listening experience.​

Sound Field Optimisation

By detecting ambient noise, sound settings can be automatically tuned to deliver clear sound even in noisy or outdoor environments.
