How much overhang is ok between a speaker base and the stand top plate?

This thread extends another I posted about "mass loading" stands.
As I mentioned in those threads, I’m choosing speaker stands for my Salk SS 6M speakers. They measure:

20” H x 9 1/8” W x 14 5/16” D

There are many options for speakers stands, but the choice is complicated by the size of the speaker’s width and depth.

Many stands feature a top plate that is 6" x 6" or 6" x 8" or 7" x 7" etc.

On *any* of these top plates, my speaker would hang off the sides and front/back by at at least 2-3 inches.

For example, I’m considering Target stands but am not sure if it’s worth spending good $$ on a stand if there is this amount of overhang.

Seeking opinions about the "overhang" issue between speaker base and stand top plate. How important is this for the sound? How much overhang is too much?

And if it was necessary to have a top plate made locally to go along with the stand, would I just affix it myself? Have it welded on? I didn’t want this to get so complicated.

Thanks for your opinions.

Getting technical, you may want to read a female treatise on the subject as your question does involve a "Parallelogram of forces".
However, you’d have to determine the centre of gravity of your particular speakers and THAT, when standing on the supports FIRST!

Then read the answer to your question, see below:
https://historyofwomenphilosophers.org/chapter-12-of-composite-motion/

Once done add at least some 20% safety margine for your cat, or other possible interference with gravity.
And now have fun.

PS how to find the centre of gravity for your setup GOOGLE it, eh.

Personally I prefer an ample amount of overhang but there can't be too much. I believe in a good balance between overhang and firmness. Good support is crucial!

Atacama in the UK makes nice stands in an abundance of sizes. I've used them for years....

I'll look into Atacama. Need 20" or about 500 mm height...

I use Audioquest Sorbothane mats to adhere my 1 cu. ft. speakers to Target HR50 stands (with stance plates).  These seem to serve well as vibration blockers, metal ringing dampers, and hold the speakers firmly from falling if accidentally bumped.  They also don't materially change the height of the speaker, and best of all...don't cost much ($49.00 @ AA).  On the overhang question, don't be overly concerned as long as you have a rigid stand and a secure attachment to the speaker, either by adhesive or by screwing up through from the bottom.  Don't want to mar the veneer on the bottom...try the sorbothane...
