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.

I would expect it would be the same on Duo 2.0 and 2.1. I remember when I first bought my Duo 2.1s that Jim Smith called me up shortly thereafter and told me to experiment with reversing the polarity on the SUBS because, according to AG, some may have been wired in reverse polarity.I will experiment with this upon my next listening session. Thx for the heads up.

Guess what??? I tried the polarity reversal on my horns and it definitely was NOT the better solution for me. However, while futzing around behind the speaker I noticed that my subs were NOT hooked up in reverse polarity (an oversight, probably, from the last time they had to be moved to accomodate hurricane repairs on the living room roof). So I made the swicheroo and BOOM (or is that BAM), better bass definition and spatiality and increased intelligibility from top to bottom. So, whether they were wired in reverse polarity during assembly or, as Larryi pointed, simply integrate better in my particular room with polarity inversion, believe me...whatever the reason, one way is audibly superior to the other and I would encourage all Duo and Uno owners to experiment.
