WANTED: Happy members who like to discuss audio and other topics related to our interest. Desire to learn and share knowledge of science required as is 20 years of participation in forums (not all true). Come here to have fun, be ready to be teased and not take online life too seriously. We now measure and review equipment for free! Click here for details.
Heard this model as an expo, I spent very little time in that room though and have no recollection how it sounded.
For a more conservative design and price, they have this:
Looking at the Stereophile measurements of one (102dB sensitivity!), the crossover integration is really poor, but John Atkinson states he had to measure at 1/2 the recommended listening distance, so that may be why, but besides that the on-axis was not impressive, but the off-axis was surprisingly well behaved albeit very narrow and having the mentioned crossover issue.
At one time I was obsessed with the idea of getting Avantgarde Duos but think my older self would be less impressed by what may be a none-too-smooth frequency response (circa 1990s). The speakers I listened to were partly driven by Art Audio PX25 single ended triode amplifier. But having built quite a few SETs have since grown far less interested in such inefficient things, and would now be far more impressed by a system which delivered fantastic sound while only consuming a few watts of power!
Have listened to various Avantgarde speakers many times - in home, audio clubs, shows etc.
They can sound very bright. Love the "dynamics" and looks, but would never buy a pair. Actually, the sound makes me feel sorry for those who spend so much on them....
I agree, I love the look of the second ones (the Zero 1) and actually, the only (limited) measurements I can find on the second one actually looks quite good!
From Stereo Magazine:
Very limited measurements by our standards but flat on axis seems to clearly be a goal.
No measurements. I’ll try to do some but my wife hates it when I run them and the opportunities for doing them when she is out are limited during these lockdown times

I love them.
Completely subjectively I love the big soundstage (yes I know… they are big so it's probably sighted bias), I love the dynamics and how they fill quite a big unevenly shaped room (roughly 4.5m X 10m).
Also, and this is important to me, I really like how they look. I bought them fully aware that a part of that decision had zero to do with how they sound or measure.
I don't think that the problem comes from the crossover but from the operating range of such horns. A full-horn speaker must be at least 4-way. You won't any measurements of such behemoths:
Stereo & Image produced basic measurements of the Avantgarde Trio + Bass-Horn but most measurements are of 2-way + bass-bin horns, 3-way + subs if you are lucky.
Not a fan of their loudspeakers whatsoever and for the money, I could never recommend anything from that company... To each their own though. Preference is inviolate. After hearing the Duo Mezzo and XD, I’ve concluded that they are very forward and aggressive sounding. Regardless of program material or even volume, they hurt my ears to the point of a headache. However, that isn’t to say I wasn’t impressed with the dynamics of them. Both very expensive setups in large rooms with tube equipment. When I think of Avantgarde, Klipsch suddenly comes to mind and not the Jubilee (I actually enjoyed those). They can get ridiculously loud with minimal power though and put off a massive soundstage if you’re into that... Hopefully my comment isn’t offensive towards anyone as that is not my intent. That is my experience with Avantgarde though.
I’d be interested in hearing the Zero 1. Aesthetically, I find them to be rather intriguing and I’m pretty certain it is an active design.
I have liked the ones I have heard. A friend has some.
The full range horns are too expensive for me and I wouldn't pay a fortune for the smaller ones which are actually box speakers for most of the music.
I preferred the Tune Audio Anima
