Avantgarde Uno 2.0, 2.1

Try it both ways, with a test CD track at the adjustable crossover frequency (mine's set a bit over 140Hz on Duo Omegas) - whichever has higher output is the way to go.

No harm in trying it both ways. But, it is not necessarily the case that the best orientation is all drivers in phase. For MANY speakers, the best integration is with a driver out of phase with respect to the other. This is dependend on the design, particularly the crossover.

I like the Duos myself, but I too find there are problems with the woofer. I doubt that it has to do with the woofer being out of phase. Woofers are quite hard to integrate with horn upper frequency drivers. Many horn systems eschew really deep bass in favor of faster drivers that can keep up with the horns. Perhaps driver transient response is an issue, perhaps something else. I found the bass on the Duo a bit uneven, such that certain notes seem to be a bit overemphasize and bloated. But, like EVERY speaker, compromises have to be made; on balance, the Duos are quite nice speakers.

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.
