Madfloyd,
Here are two things to pay extra attention to when setting up the 5As. They probably apply to a large extent to any speaker setup, but I found they are especially important when setting up the 5As.
1. To get maximum benefit from the time alignment, these speakers need to be vertically parallel to each other, both side to side and front to back. Even small errors can cause readily discernable variation in the image as you move your head around.
Don't assume that the speakers are vertical just because they are on 3 cones resting on the carpet/floor. Tighten the cones, remove the grill top, and level front to back and side to side by readjusting the cones. You might be surprized at the amount of adjustment needed.
2. To maximize the phase integration in the image, these speakers need to be the same distance from front and side walls, and have the same toe in. Minimizing variation in these distances, while unavoidable in unsymetrical rooms, adds to image clarity and depth.
A small lasor is very helpful for setting toe in. Measure and place some tape on the back wall where you want each speaker to be aimed, and use the lasor to get a precise alignment.
These are refinements and you can do them after finding the preferred location of the speakers and getting familiar with the image and sound. They are good rainy day afternoon tweeks that will bring satifying results.
