Avantgarde Uno 2.0, 2.1

The problem with bass integration has to do with time delay. the subs starts around 2 ms behind the horns. Look at the last stereophile review of the uno nano (in particular the step response).
Only way to fix it (besides removing the subs from the frame and moving them closer to the listening position) is to bi-amp them and put a digital delay on the horns. that's what I'm doing on my omega duos

Locational time delay might be a factor in integration, but, having experimented with horn systems, it is usually a minor consideration. You can move the bass driver much closer to the listener and if the bass driver is not well suited to the task, it will still sound slow or lumpy or whatever. The particular signature of horn drivers is quite hard to integrate with woofers, particularly where an emphasis has been placed on getting really deep bass from the woofer. Most decently integrated horn system have woofers in bass alignments that don't really allow for deep bass--e.g., horn loading or onken bass reflex--unless truly giant cabinets are used.

Like all systems,Avantgarde speakers reflect a particular set of tradeoffs, the best one can do is optimize performance--particularly placement of the speaker.

I was charmed with the horns but disappointed with the poor bass of my UNO G2, and I was not aware of reverse polarity trick, but I have simply replaced the internal amplifiers with cheap ClassD Hypex modules... and they now ROCK !
