To Myron and others who have struggled with setting up Avantgarde DUO's:
If you cannot get the horns to line up according to Avantgarde's instructions, you have an older version of the tripod support. Avantgarde changed the hole positions, did not tell anyone (TMK), and printed instructions for the new support system. In addition to the suggestions already provided, please try the following:
1. Mount the high frequency horn in the middle hole.
2. Mount the midrange horn exactly 21cm (slightly over 8") from the high frequency horn, as measured from the top of the rear housing of the high frequency horn to the bottom of the rear housing of the midrange horn. The middle hole for the midrange horn will space the units exactly as Avantgarde intended.
3. Now you can slightly tilt the entire speaker either forward or backward, as required by your listening position and as suggested by Avantgarde.
4. Should you desire to move the horns to a higher position, make sure you move them together, without changing the distance between them.
5. If you experience lack of proper bass integration, try spiking the sub cabinets. I use 2" Audio Points on the rear and 1.5" Audio Points on the front. This combination positions the speakers at the precise angle and seamlessly integrates the subs with the horns.
6. It is also perfectly safe to reverse polarity of the speaker wire bass connections, providing both speakers are wired the same (experiment).
Once properly set up, the DUO's will not disappoint. Best of luck.
