Small Discrepancies in Speaker Placement

So, of course, after a hard day’s work, I had nothing better to do than futz around with speaker placement. After some trial and error, I found that my speakers (JA Pulsars non-graphene) work best when pointed straight ahead with no toe-in. When placing them, I inadvertently put the left speaker about 1/2" closer to the side wall than the right speaker. They were previously exactly the same distance from each side wall. With this new, slightly unequal placement, the speakers completely disappear. This was confirmed by my wife who, without any prompting, told me that the music now seems to be coming from out of nowhere, whereas it was directional previously. I can’t explain this phenomenon ... does 1/2" really make that much of a difference? HEY, turn off your dirty minds. wink Any opinions would be welcome. Thanks.

@doni ... Jeff Joseph recommends no toe-in for the Pulsars.

As @drrsutliff said distance between speakers may effect imaging.

And yes, 1/2 an inch matters. Even a 1/4 but I only measure to 1/8 cause I’m OCD.

When I got my latest pair of speakers I was constantly moving them for about 6 months in very small increments.  At one point I found that magic spot and it was after repositioning them only about an inch!  Keep in mind that rooms are not really acoustically symmetrical, windows, an extra chair that is only on one side of the room so moving only one speaker can make a big difference!

Same here. I've had mine for over a year and thought I had it down pat until I started binging on some Hannibal series blu rays. Mads Mikkelsen was very difficult to follow due to his accent and then I aimed my speakers just a tad more inwards and presto! I could now understand him.

It all boiled down to my tweeters being offset to the outside and I measured them using a laser centered right down the middle. What used to work for me resulted in the tweeters being a touch too much away from me. 

It amounted to about 1 1/2" difference than my usual way of setting up but that's all it took for that turn for the worse. Even with music, the center is more fully realized and the music is a touch more dynamic even at the same volume.

All the best,
