I just finished running the auto setup and I hit save, but it changed the front l/r speaker size from large to small. Will there be any difference in sound and should I change it manually to large? Also, the subwoofer is set to l/r+sub. Should I change it to lfe only? Thirdly, What are your recommendations on speaker x-over for the front l/r, surr l/r and surr back l/r? My speakers are below. Thank you in advance.
