Avantgarde Duo set up.

Genltlemen(and gentle women), I have a question.

In the manual, Duos require a set-up whereby the midrange horn is one hole higher than the tweeter horn (in their respective hole sets). Making the gap between the horns in the vertical axis larger and keeping the mid/high horns the correct distance apart from an acoustic perspective.

The manual also explains a "bead and ????something" method where you tilt the speaker front to back to get the bottom of the midrange horn visually touching the rear of the tweeter horn to get the correct position on the vertical axis.

I simply cannot get this to happen. With the reccommended horn position I have no chance of making this happen from my seating position. I'm much to low. Even with both the horns in the same holes, ie both two holes from the bottom, I cant get this " bead and ?????" method to line up. This is probably a function of my seating position being too low and being a faily long way away.

So I suppose my question is which is the best compromise ? Having the Horns in the Manual reccommended position. Or getting close the the "bead and thing" principal and having the horns closer together in the vertical axis.

Looking at various Gallerys on the web it looks like many people have their duos set up with the horns closer toghether than reccomended in the vertical axis.

I'm told that setup is critical with Duos so I'd like to get it as right as possible.

In your vast, collective experience which would be the best way to go ??

If you read this far...... thanks very much.

Myron.

Yep, I was a little confused about the reverse polarity comment as well, since it sounds like, to invert polarity on the woof, you'd need to change both the mid and the tweets relative to the woof.
One suggestion that Jim Smith makes, aside from hooking up at the midrange, and going from there (and there is a HUGE difference in sound between the stock jumpers and the Cardas Golden Reference- no exaggeration here) is on toe in-
seated at the listening position, look toward the outer rear bolt. Its head should line up visually with the inside of the front upright rail on the same side. Sonically, the speakers seem to snap into focus. I didn't find a need to change the recommended height of either horn.
