Avantgarde Uno 2.0, 2.1


Hello All,

Just an FYI for the Avantgarde Uno owners out there. I did an impulse response on my speakers with the tact equipment and found out that the horns are operating in negative polarity and the sub is positive. That is the main reason why a lot of owners are noticing a discontinuity of the bass with the mains. To correct this, you would have to reverse the positive and negative leads on the HORNS not on the sub.

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 !
