Guys,
Thanks a lot for the last couple of posts. I've been thinking that because these speakers are so easy to relocate due to lack of floor spikes, that I'm going to try moving them much further out into the room than is practical on a day-to-day basis. If I find a good spot, I'll just mark it with tape and then move the speakers when I want to sit down for some serious listening.
Mapman, I also have "sort of" an L. shaped room... although it's really pretty hard to describe unless I were able to actually sketch you the floor plan! ;-)
In any case, because my seating position is pretty much restricted to a particular piece of furniture (a day bed) in a kind of niche opposite the speakers, I'm a little restricted as to seating position. Actually, the 100s, being semi-omnidirectional, with their wide sweet spot, are great for a setup like this, because you get a nice sound pretty much wherever you sit.
On the other hand, the right-hand speaker is a mere 18 inches off the side wall, and I'm wondering if that isn't compromising the way the system currently sounds. It's NOT that it sounds "bad," but I keep thinking that I'm not getting the most out of the system. I'm going to try moving them WAY out into the room, and I'll see what happens... I will report back... ;-)
