Speaker Support - Three Feet or Four

I'm thinking of going to a three-point foot system for my Gershman Acoustics Sonogram floor standing speakers.

Reason for doing this is that the hardwood floor shifts with the seasons and a four-point system can require adjustment throughout the year.

Each speaker weighs 63lbs, has a baseplate footprint of 10.75" wide and 16" deep. The basplate is 0.5" larger all around than the actual speaker cabinet

I believe the centre of gravity to be just below mid height and relatively centred from a footprint perspective.

I plan on mounting the two feet that levels the sideways attitude on an outrigger.

Are there any advantages to placing the outigger feet at the back or the front?

or is this just a matter of using the best config for stability based on centre of gravity?

Is there any advantage to having the feet equally spaced or use the maximum distance possible within the confines of cabinet footprint + outrigger dimensions ?

Or should I just stick with four feet?

Note: I don't have to worry about kids or pets bumping speakers :-O

Thanks in advance

Three is fine if you have no problems with tipping. Generally you would want the feet as far apart as possible.
Only if it introduced some sort of resonance would that not be best.
And two feet front, one back is right.

I have done it both ways with several different speakers but always using Sound Anchor stands, which add significant weight and lower the center of gravity. My current speakers are 110 lbs each (not including the stands) but are moderately tall and somewhat slender. The Sound Anchor cradle bases extend the footprint and I tried using three Eden Sound Bear Paws for a three point support. That simply was not stable enough and I switched to four feet, which I find to be a much better solution for my present situation with the feet piercing carpet and supported by the underlying concrete floor. I previously used Sound Anchor stands on three feet to support Alon 5's on a suspended hardwood floor. In that scenario, the three feet worked fine. However, it is my recommendation that 4 feet is better than 3 feet to support large speakers.

Alas, for these speakers at least, the three feet option made them quite unstable.

I've now gone back to four feet - very stable

Still considering the outriggers, but with a four feet

For my KEF 104/2 speakers I use 4 Edensound Bearpaw Sr feet that have the Triceratops option on the top of the footer. This is the Edensound version of Mapleshade's triplepoint feature. Each Edensound Bearpaw Sr was then pre-drilled so that the Bearpaw senior could be attached to the KEFs. I felt this was the most secure option but man oh man did the Bearpaw Seniors as feet really add weight to the KEFs. Moving them around was a real work out. I say stick with the four feet. In my instance I've got a lot of stability and I have kids to worry about.
