Listen loud and clear

The technology in the ULT FIELD 7 works in harmony for a better sound quality. The X-Balanced Speaker Unit gives deep, punchy bass and vocal clarity even with loud sound. A high efficiency tweeter provides crisp and spacious sound for high frequencies. Passive radiators optimise the sound to enhance clear bass. Put it all together and you get a great sound worth sharing with your friends.

Powerful sound with X-Balanced Speaker Unit

Our X-Balanced Speaker Unit features an almost rectangular diaphragm, for an increased surface area compared to conventional speaker units. The approx. 114 mm x 114 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. For a richer, clearer, and more rewarding listening experience.
