Toe in is crucial

Amen brother, I spent 6 months adjusting my current speakers before I was satisfied.  Everything matters but I've found that the type of tweeter matters most to get a good synergy.  Toe in defiantly matters!

A couple of years ago I made floor mounted angling devices that attach to the plinths of my Cornwall 4's. These brackets are perfectly centered on the wall behind the speakers and can be used to change the distance between the speakers relative to my center listening position, and then the angles between the speakers to high precision - about 1/16 of an inch. The speakers are both attached to the devices on one corner that pivots to the common wall behind them. To alter the angle from the wall is simply a matter of pivoting the speaker on the attachment point while measuring the swinging speaker corner to the wall behind it. A yardstick with 1/16th inch resolution controls the amount of "swing" (angle.)

Being able to easily adjust toe in quickly and effortlessly with such fine control was one of the best mods to my system.

@hilroy48 that is very fast timing. I get to move them around for several days in and out during listening till I find what I want.

@czarivey  The dealer I bought them from, Brought some reference Media he likes and know what it is supposed to sound like. From there we played my music for the final tweaking that suited my ears. I have the option to move my listening chair back and forth as well. 

When I get new speakers I always try no toe in and on axis back to back to see the extremes. I almost always end up somewhere in the middle.
