Speaker Stand Height And Recommendations For Spendor SP100 Speakers

It has been a very long time and I do not have the Info to make a sound decision on a Set of Speaker Stands for my recently acquired SP100's.

My sitting Ear Height is 38 1/2" and Speakers will be 9 Feet away.

Tweeter in SP100 is 17 1/2" to Center from the Bottom of the Cabinet. Sound Anchors told me recently that their 4 Post Stand for the SP100 is 16" High. In addition to another puzzlement is they also told me Top Plate will be 14" Wide & 16" Depth but I am measuring the SP100 Cabinet as 14 7/16" Wide & 17" Depth.

My Footers will add 1 1/2" approximately which equals 35" for Tweeter Height from the Floor. I recall the Original Sound Anchor 3 Post Stand had two adjustable Studs at the back of the Stand.

My questions are;

1) Does someone have a pair of the Original Sound Anchor SP100 Stands and could I trouble you to give me a dimension from the Bottom of the Horizontal Base Tube to the Speaker Top Plate at the front.

2) Does the SP100 require that the Tweeter be at a Sitting Ear Height? If it does, can you shim the Front Base of the SP100 to accommodate.

3) It is likely that I will go for the Sound Anchors but does anyone have any other Speaker Stand Recommendations.

SP100's will be on a Second Level suspended Plywood Floor with Carpet. My previous Sound Anchor Stands provided good stability on this semi wonky Plywood Floor but I would like some recommendations since I have been far removed from the Market.

Thanks in advance,

David
