I wanted an m20 thread, but could only find an m10 or m14.
I will machine a short m20 threaded bar to m10-. M20 one end, m10 the other end, This will fit my needs perfectly.
I'm surprised Thomann did not have m20 speaker stand adaptors, maybe I didn't look hard enough.
This m35 speaker stand, to m20 thread adaptor is great, I can now use thomann's m20 thread top hat (flange) on the base of my smaller speaker enclosures, with this "removable" adaptor.
