First, I believe the reason that you set up the crossover to 35Hz is because the Maggie can go deep down to 35Hz. You may want to check the error rate. If it is -3dB or more, you can set up the crossover to 40Hz to prevent the LF distortion by the Maggie.
The placement is always a tough part, which requires a number of fine tunes. You can either put the sub closer to the corner if you would like to get more bass. However, achieving the overall balance and clean, solid bass is more important.
Due to the speed of the Maggie is very fast, you can use good speed silver cables for the sub to obtain a better match with the Maggie.
Hope the above helps. Good luck.
