Very cool setup. I will have to agree on the recommendation to reduce the toe-in. Mine are slightly angled, but I came to the final position after trying various angles over a period of weeks. To give you an idea of how little they are angled, the sweet spot is 9 feet from the mains and the toe-in is about 7 degrees.
