Toe in will typically increase direct high frequency, but decrease reflected high frequency. Reflected high frequency can be more objectionable.
A tiny bit of toe in can offer some compensation for limited available listening distance. For example; with a 10’ center to center speaker width, a <2 degrees toe in can allow an 8’ listening distance to more closely approximate the preferred 10’ listening position.

thanks Guys.  mine are toed in maybe 3-5 degrees. the right speaker has nothing beside it to create additional HF.  the left speaker has a wall near it but i have a big sound diffusion panel at the first reflection to help.   I use a laser level across the front of the speakers that projects a laser line onto the other speaker. it barely bisects the side of the speaker and when i get the same thing on both speakers,  i have got them toed in the same.  does that make sense?  i would post pics but there is no way to do it as far as i can tell. 

I've owned the 3.7s and 2.7s.

Like most speakers, toe-in increases the high frequency content, toe out reduces it and mellows out the sound more.

I toe them out somewhat, not to just forward facing, but enough to have a smooth balance and to increase the apparent soundstage and imaging size.

Good Friday

Same here i never toe in my 3.7s, this is definitely the best results i got but i'm lucky to have plenty of room from the side walls like about 6 feet.
