    Nice big room!

    Listening position is always an issue.. yes, do testing to find the best spot. Parallel surfaces aren't bad in themselves and for a mixing environment, flutter echo shouldn't be an issue except between the front and back walls.

    Treat the front, left and right symmetrically and find the spot where the low frequency is the flattest for the mix position.

    Testing: I highly recommend Room EQ Wizard. http://www.roomeqwizard.com/ It's free and on par with the best paid software. I also highly recommend the mic from MiniDSP https://www.minidsp.com/products/acoustic-measurement/umik-1
