Each room is different, as are the speakers. The Cardas method is a good point to start from, but it is not always the best for many rooms. A good way to find the correct position for placement is to start with a equilateral triangle from the listening position, then the distance from the wall behind them, adjusting for bass output. Then, adjust the width the speakers need to be from each other. Lastly, work on the toe-in of each. It may take several listening sessions to get them right, so don't get in a hurry. Have fun!
