Speaker toe in

ganash, you bet. I always listen with my eyes closed when I am listening seriously. Visual cues can easily distort your audio perception. Our eyes and ears are wired together. As an example if one inner ear malfunctions your eyes will start to drift to that side then your brain says "look ahead you idiot." the result is called nystagmus and what you get is vertigo. The room spins. 
Put on Herbie Hancock's Sextant album and play rain dance with the lights out or Weather Report's Mysterious Traveller and Nubian Sundance. 

When your room is firing on all cylinders the best toe-in is no toe-in.

This is so incredibly speaker dependent.
As for imaging, I find that toe-in affects whether musical instruments appear in a continuous range from speaker to speaker. If there is a missing center, or there is a L, C and R but nothing in between, toe-in can be the game changer.

And yes, too often speakers are too far apart for the room they are in.

Not just toe-in. Tilt-back.


My speaker soul-brother, Troels Gravesen, and I have both found that sometimes when we design a speaker to be listened with the ear at tweeter height the best place to listen ends up being a little between it and the mid-woofer. 

The point is, of course, to have the most enjoyable listening experience for you.


No reason not to experiment even when all the tools and tech says to listen another way.

I've been experimenting to dial in my Harbeth Super HL5 Plus speakers now that I have my custom stands.  Sitting flat on the stands, they lose some of the midrange and treble.  Tilting them back a bit really opened them up.  They sound best to me either facing straight ahead or with just a hair of toe-in.  I tried some more aggressive toe-in and didn't like it.

wow ¡!¡! i tried the more extreme toe-in position with the intersection about a foot in front of me face... i am liking it. deeper soundstage and the AirPulse Model 1 always had invisible midrange.. but now it is ghostly. soundstage width had decreased but I am slowly inching the speakers wider.. instrument positioning in the soundstage is improved as well...

update #1.. the monitors do not like to be too close to sidewalls..
