Speaker Width?

What is the big deal about XLO Test CD?

Is it any similar to a combination of...

and one like this (with a different cover, but essentially the same, it does have polarity check, etc.)...

Now, imagine how I felt. I have not recovered yet.

Don't know if it's been mentioned in the thread but R. Vandersteen has a speaker placement method that works in my room.  Divide the width and length of the room by odd numbers and the intersection points are potential spots for placement.  

Then careful trial and error determines the best placement - and he mentions when you find it you will know and he is correct in my case.

In the first room I had my system in the sweet spot was incredibly small. A difference of inches and I'm typically not a fussy audiophile about this sort of thing but in that room it was as you say, you knew the right spot immediately and all others were noticeably worse. Even turning my head to one side made a difference in the soundstage.

In my current room the sweet spot is not so small and there are several of them. I don't know why. My room has a few hard flat surfaces but it has 10' ceilings, carpeted floor and soft furnishings everywhere else. Maybe that helps?

Sorry to chime in with some basic truths here. What I see is a really bad listening environment especially for those speakers. Way too small a space. Look at listener position, against the wall. Talk about reflective heaven. Jeez. I recommend storing those speakers for the future house, get some decent bookshelves speakers and then make them sing as best as possible in that space for as long as stuck there. Wow, I sound like Geoff. Sorry!
