"The DUOs do all of the normal audio tricks of imaging and soundstaging; plus a few not so common audio tricks like the realistic recreation of a living, breathing, soundspace; lifelike dynamics and life-size aural images. Musically they allow the emotional content to come through in spades, and they play the beat right. More than any other speaker that I have had the pleasure to enjoy, the DUOs immerse me in an musically convincing soundspace that is a near musical epiphany at every listening session. (AUDIO ASYLUM, J. Day, USA)

“To round all this up, the Avantgarde hornspeaker is amazing. Even after hearing the DUOs it is like going from the Ferrari F40 to the Ferrari Enzo. For those looking for the speed of electrostatic panel loudspeakers yet with the easy of drive and dynamics of horns, the DUOs should make your very short list of must audition. Of course in the end what really matters is that you ... Enjoy the Music.” (ENJOY THE MUSIC, Steve Rochlin, USA) 
“The DUO OMEGA gives a whole new life to spherical horn architecture. Ning Kam’s violin is precise and at the same time beautifully condensed. Just on the spot. Yet the energy of the treble penetrates with power like in reality. The proper tuning of these special tonal characteristics is what makes the DUO OMEGA so very special. The listening is more relaxed and at the same time envolving, like having the centre front row seat in a concert hall.” (AUDIO CITE, Zhong-Hao Tao, TAIWAN)
“The totally balanced combination reveals very fast - very much. The DUO sounds incredibly natural. There are simply no colorations! The competition had no chance when our test program played real dynamic tracks. Some tracks have such an incredible dynamic bandwidth, that most conventional speakers simply smooth-off, or to it say more clearly - compress! Not the DUO´s! The best symbiosis of horn and conventional technology I know.” (AUDIOPHILE, H. Biermann, GERMANY)
“The inexhaustible dynamic reserves of the DUO show the incredible strength of this set of horn satellite and active subwoofer. Drums sound totally unplugged. No peaks or fortissimo really challenge this speaker. Piano concerts are reproduced with original dynamics. No compression effect deteriorate the thrilling experience of a life orchestra.” (STEREO, U. Rattai, GERMANY)
