Thank You for the warm welcoming. I'm not a professional video audio guy. Music, HiFi and Home Theater are just my hobbies. Although I've been computer hobbyist also since 1987, computer assisted room equalising is new to me. I'll start to fight against the 50-80Hz bass suckout that I have in my listening position!:heehee:Welcome to the Shack Vesa! Sounds like you have lots of expertise.
