@heinrichmilw,
I was wondering how you have positioned your ProAcs? I am trying to find the BEST positions for them in my room which is 18X15X8. I have currently placed them about 5 feet from the back wall and 3 feet from the side wall. Both positions are approximate for now, since I am still trying to adjust to the new sound. I have also toed them per ProAc's recommendation - speakers are facing directly at listening position, with neither side of the speaker sides seen.
