After Many Years, Different Speakers, Different Spaces: Mine and Friends 

Speakers, like a blind traveler, do not know where they are going. 
Equal dispersion of frequencies measured directly in front in a foam box.

Position(s) Angle of Dispersion and Initial Reflections.
Speakers must stay where placed, but readily move with effort.
Heavy: 3 wheels; Mid/Smaller: 3 bottom skids, sized and placed for weight of speaker.

Tilt speakers back, to direct the tweeters at seated ear height.
to maintain volume balance of narrow tweeter frequencies with wider mids and upper bass dispersion.

Tilted back also alters the angle of initial reflections off the floor and ceiling
combined with toe-in altering the initial side reflections.

DBX Cross Dispersion Method (developed for home theater front speakers):
unique shape/angle of dispersion/multiple tweeters: set up once.  

speaker your side: closer thus more volume, but, direct dispersion from opposite side speaker increases it's volume, i.e. a trade-off creating wide imaging. Note: their speakers were designed to provide this without altering their toe-in

Toe-In Alternates: speakers must stay where positioned, but move with effort. 
wheels, skid plates sized relative to speaker weight/surface material.
no spikes which prevent alternate toe-in and/or alternate positioning.
spikes: I tried them, wasn't I smart: no improvement anywhere I have listened, mine or others whereas alternate positioning and alternate toe-in makes substantial differences. (far more than any subtle improvement you perceive with spikes).

1. Best Positioning (may involve other compromises) 

Mine: move speakers further forward and further inward, i.e. further away from corners and side walls. Compromise: speakers partially limit access to equipment both sides.

2. Single Listener: tweeters each side aimed at listening position. To keep volume of narrow dispersion high frequencies relative to volume of mids and upper bass

3. Two Listeners: use DBX Cross Dispersion Method: right tweeters aimed at left listener; left tweeters aimed at right listener. Result: wide decent enjoyable imaging, each listener hears 'enough' of the opposite side.

    Hey, How do you relate to Cole Younger?

    why 1896?

    He had to be near deaf in his shooting side ear.
