Speaker Spike Help


Looking for assistance with two issues related to a rear spike for my specific speaker application.

A.  Recommendations for a spike (DOES NOT have to end in a sharp point) of the following size:

--- 0.375 to 0.875 inches (~10mm to ~22mm)
--- 1 inch / ~25mm maximum diameter / width
--- flat top OR with threads


I'm currently using the Eden Sound Hemi-Spike (extra large, flat top, brass):

B. What do you recommend for securely attaching a flat top spike (the Hemi-Spike has a 1 inch / ~25 mm diameter) to the speaker cabinet bottom?

At present, I'm using a disc/ pad with double sided adhesive. 


[Note: The flat top, with adhesive, is a first step solution. I fully realize a threaded spike will offer superior coupling]

[Note: I have already considered Star Sound Audio Points]


Thank you very much!

BDR Cones are exact size you need and outstanding. They are flat on top and tapped for 1/4-20 threads commonly used on a lot of speakers. If the speaker is heavy enough then its weight alone will hold things in place and in that case you could use 3 per speaker. Although 4 threaded is better. Also they work great by themselves, but even better with BDR Round Things under them. On carpet or whatever, does not matter. 
Thank you very much, @millercarbon  I will look them up and follow up with you, should I have questions.
I should have made note of this: My speakers are bottom ported and by design, there is a gap (from the floor) front to rear AND a rising angle / tilt rear to front.

I’d like (prefer) to maintain the designer’s height and angle for the speaker. Therefore, spike height, spike diameter, and contact point are all important considerations.

Also, maximum thread size is 1/4-20. Less is better. Metric equivalents will work.
