Still "tweaking" the placement of my L200b speakers and was wondering how far back other members were seated from their large monitors (L300, 4333, L220 etc). I'm seated roughly 15' from my L200b with a Pioneer 53" rear projection tv in center. Works very well for viewing but I have a feeling the seating position could go back another five (5) feet for listening. My listening room is 19'x25' with 13' cathedral ceiling, L200b and tv situated on narrow end (19'). I'v heard the term "farfield" used and wondered if it had any specific boundries.
