Avantgarde Uno 2.0, 2.1

Hi Bmwmcab

I asked you this very question last year and didn't realize you answered it, been a while since i've been on audiogon since i bought my Uno's. I guess i will try to reverse the polarity on the horn side and see if that sounds better. I was confused after buying my horns about the reversing of polarity since everyone had a different opinion. I did find that the subwoofer didn't integrate seamlessly with the mid-drivers but lived to deal with it. Thanks for the heads up i have something to test now....

Runmeshaw,

Give it a shot and let me know how it goes.

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.

Acresverde,

Ok. Now try just reversing the positive and negative leads on the speaker wires from the amp. Let me know how that is.

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
