Test conclusion Hobby HiFi Heft 1/2017: Mid-high coax with aluminum and titanium membrane. With the CX 3.1, Omnes Audio now delivers an even better midrange coax at a still amazingly low price. He remained unchanged!

Test Klang + Ton Issue 3/2016: Whether compact or fully grown, the Omnes Audio CX3.0 makes an outstanding figure in any combination from 200-300 Hz and is surprisingly good-natured for a compact coax with hard membranes. The price is also very attractive. Also for the numerous use – for example in the compact Surroundset with excellent space – there is green light. Conclusion: Still an extremely attractive driver for a variety of applications.
