Bill the sevens

Tech support is awesome! They say 1/4-20. So online M6 is a close enough match? The Sevens are on back order until first of January. Will keep updated if I find the spike set that work.

Have scoured the Internet for days cannot find the thread diameter and pitch for buying some mounting screws for the bottom of them or possibly using spikes to prevent resonance from the cabinet they will be sitting on. Please let me know what size screws or spikes for these. The KS speaker stands come with them but the manuals do not tell you what size they are please please help
