Powerful sound with X-Balanced Speaker Unit

Our X-Balanced Speaker Unit features an almost square diaphragm, for an increased surface area compared to conventional speaker units. The 320 mm x 320 mm large woofer unit gives 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.
